The structure and function of the beta 2-adaptin appendage domain. (1/20)

The heterotetrameric AP2 adaptor (alpha, beta 2, mu 2 and sigma 2 subunits) plays a central role in clathrin-mediated endocytosis. We present the protein recruitment function and 1.7 A resolution structure of its beta 2-appendage domain to complement those previously determined for the mu 2 subunit and alpha appendage. Using structure-directed mutagenesis, we demonstrate the ability of the beta 2 appendage alone to bind directly to clathrin and the accessory proteins AP180, epsin and eps15 at the same site. Clathrin polymerization is promoted by binding of clathrin simultaneously to the beta 2-appendage site and to a second site on the adjacent beta 2 hinge. This results in the displacement of the other ligands from the beta 2 appendage. Thus clathrin binding to an AP2-accessory protein complex would cause the controlled release of accessory proteins at sites of vesicle formation.  (+info)

The highly conserved C-terminal dileucine motif in the cytosolic domain of the human immunodeficiency virus type 1 envelope glycoprotein is critical for its association with the AP-1 clathrin adaptor [correction of adapter]. (2/20)

Short amino acid sequences in the cytosolic domains of transmembrane proteins are recognized by specialized adaptor [corrected] proteins which are part of coated vesicles utilized to transport membrane proteins between the trans-Golgi network (TGN) and the plasma membrane (forward and backward). Previously, we and others reported that the membrane-proximal tyrosine residues Y712 (human immunodeficiency virus [HIV]) and Y721 (simian immunodeficiency virus [SIV]) in the envelope glycoprotein (Env) of the primate lentiviruses are crucial for the association of Env with clathrin-associated adaptor [corrected] complex AP-2. The same tyrosine-based endocytosis motifs in the cytosolic domains (EnvCD) of transmembrane gp41 of HIV type 1 (HIV-1) and SIV, respectively, were also shown to modulate the interaction with TGN- and endosome-based clathrin-associated complex AP-1. Our findings suggested that EnvCD binding to AP-1, unlike the association of EnvCD with AP-2, is dependent largely on residues other than Y712 and Y721. Here, we tested if motifs downstream of Y712 affect HIV-1 EnvCD-AP-1 binding and Env trafficking. Mutational analysis revealed that the C-terminal leucine-based motif in Env was crucial for the recruitment of AP-1 in vitro and in Env-expressing cells. In addition to affecting Env-AP-1 association, mutations at the C terminus of Env also altered the subcellular localization of Env, suggesting that proper post-Golgi routing of Env depends on its recruitment of AP-1. Finally, the C-terminal dileucine was shown to assist the membrane-proximal Y712 motif in restricting the cell surface expression of Env.  (+info)

PACS-1 binding to adaptors is required for acidic cluster motif-mediated protein traffic. (3/20)

PACS-1 is a cytosolic protein involved in controlling the correct subcellular localization of integral membrane proteins that contain acidic cluster sorting motifs, such as furin and human immunodeficiency virus type 1 (HIV-1) NEF: We have now investigated the interaction of PACS-1 with heterotetrameric adaptor complexes. PACS-1 associates with both AP-1 and AP-3, but not AP-2, and forms a ternary complex between furin and AP-1. A short sequence within PACS-1 that is essential for binding to AP-1 has been identified. Mutation of this motif yielded a dominant-negative PACS-1 molecule that can still bind to acidic cluster motifs on cargo proteins but not to adaptor complexes. Expression of dominant-negative PACS-1 causes a mislocalization of both furin and mannose 6-phosphate receptor from the trans-Golgi network, but has no effect on the localization of proteins that do not contain acidic cluster sorting motifs. Furthermore, expression of dominant-negative PACS-1 inhibits the ability of HIV-1 Nef to downregulate MHC-I. These studies demonstrate the requirement for PACS-1 interactions with adaptor proteins in multiple processes, including secretory granule biogenesis and HIV-1 pathogenesis.  (+info)

The beta-appendages of the four adaptor-protein (AP) complexes: structure and binding properties, and identification of sorting nexin 9 as an accessory protein to AP-2. (4/20)

Adaptor protein (AP) complexes are essential components for the formation of coated vesicles and the recognition of cargo proteins for intracellular transport. Each AP complex exposes two appendage domains with that function to bind regulatory accessory proteins in the cytosol. Secondary structure predictions, sequence alignments and CD spectroscopy were used to relate the beta-appendages of all human AP complexes to the previously published crystal structure of AP-2. The results suggested that the beta-appendages of AP-1, AP-2 and AP-3 have similar structures, consisting of two subdomains, whereas that of AP-4 lacks the inner subdomain. Pull-down and overlay assays showed partial overlap in the binding specificities of the beta-appendages of AP-1 and AP-2, whereas the corresponding domain of AP-3 displayed a unique binding pattern. That AP-4 may have a truncated, non-functional domain was indicated by its apparent inability to bind any proteins from cytosol. Of several novel beta-appendage-binding proteins detected, one that had affinity exclusively for AP-2 was identified as sorting nexin 9 (SNX9). SNX9, which contains a phox and an Src homology 3 domain, was found in large complexes and was at least partially associated with AP-2 in the cytosol. SNX9 may function to assist AP-2 in its role at the plasma membrane.  (+info)

The delta subunit of AP-3 is required for efficient transport of VSV-G from the trans-Golgi network to the cell surface. (5/20)

Vesicular stomatitis virus glycoprotein (VSV-G) is a transmembrane protein that functions as the surface coat of enveloped viral particles. We report the surprising result that VSV-G uses the tyrosine-based di-acidic motif (-YTDIE-) found in its cytoplasmic tail to recruit adaptor protein complex 3 for export from the trans-Golgi network. The same sorting code is used to recruit coat complex II to direct efficient transport from the endoplasmic reticulum to the Golgi apparatus. These results demonstrate that a single sorting sequence can interact with sequential coat machineries to direct transport through the secretory pathway. We propose that use of this compact sorting domain reflects a need for both efficient endoplasmic reticulum export and concentration of VSV-G into specialized post-trans-Golgi network secretory-lysosome type transport containers to facilitate formation of viral coats at the cell surface.  (+info)

Subunit H of the V-ATPase binds to the medium chain of adaptor protein complex 2 and connects Nef to the endocytic machinery. (6/20)

Nef is an accessory protein of human and simian immunodeficiency viruses (HIV and SIV) that is required for efficient viral infectivity and pathogenicity. It decreases the expression of CD4 on the surface of infected cells. V1H is the regulatory subunit H of the vacuolar membrane ATPase (V-ATPase). Previously, the interaction between Nef and V1H has been found to facilitate the internalization of CD4, suggesting that V1H could connect Nef to the endocytic machinery. In this study, we demonstrate that V1H binds to the C-terminal flexible loop in Nef from HIV-1 and to the medium chain (mu2) of the adaptor protein complex 2 (AP-2) in vitro and in vivo. The interaction sites of V1H and mu2 were mapped to a central region in V1H from positions 133 to 363, which contains 4 armadillo repeats, and to the N-terminal adaptin-binding domain in mu2 from positions 1 to 145. Fusing Nef to V1H reproduced the appropriate trafficking of Nef. This chimera internalized CD4 even in the absence of the C-terminal flexible loop in Nef. Finally, blocking the expression of V1H decreased the enhancement of virion infectivity by Nef. Thus, V1H can function as an adaptor for interactions between Nef and AP-2.  (+info)

Phosphoinositide 3-kinase regulates beta2-adrenergic receptor endocytosis by AP-2 recruitment to the receptor/beta-arrestin complex. (7/20)

Internalization of beta-adrenergic receptors (betaARs) occurs by the sequential binding of beta-arrestin, the clathrin adaptor AP-2, and clathrin. D-3 phosphoinositides, generated by the action of phosphoinositide 3-kinase (PI3K) may regulate the endocytic process; however, the precise molecular mechanism is unknown. Here we demonstrate that betaARKinase1 directly interacts with the PIK domain of PI3K to form a cytosolic complex. Overexpression of the PIK domain displaces endogenous PI3K from betaARK1 and prevents betaARK1-mediated translocation of PI3K to activated beta2ARs. Furthermore, disruption of the betaARK1/PI3K interaction inhibits agonist-stimulated AP-2 adaptor protein recruitment to the beta2AR and receptor endocytosis without affecting the internalization of other clathrin dependent processes such as internalization of the transferrin receptor. In contrast, AP-2 recruitment is enhanced in the presence of D-3 phospholipids, and receptor internalization is blocked in presence of the specific phosphatidylinositol-3,4,5-trisphosphate lipid phosphatase PTEN. These findings provide a molecular mechanism for the agonist-dependent recruitment of PI3K to betaARs, and support a role for the localized generation of D-3 phosphoinositides in regulating the recruitment of the receptor/cargo to clathrin-coated pits.  (+info)

AP-3 directs the intracellular trafficking of HIV-1 Gag and plays a key role in particle assembly. (8/20)

Gag proteins direct the process of retroviral particle assembly and form the major protein constituents of the viral core. The matrix region of the HIV-1 Gag polyprotein plays a critical role in the transport of Gag to the plasma membrane assembly site. Recent evidence indicates that Gag trafficking to late endosomal compartments, including multivesicular bodies, occurs prior to viral particle budding from the plasma membrane. Here we demonstrate that the matrix region of HIV-1 Gag interacts directly with the delta subunit of the AP-3 complex, and that this interaction plays an important functional role in particle assembly. Disruption of this interaction eliminated Gag trafficking to multivesicular bodies and diminished HIV particle formation. These studies illuminate an early step in retroviral particle assembly and provide evidence that the trafficking of Gag to late endosomes is part of a productive particle assembly pathway.  (+info)

Adaptor Protein Complex delta Subunits, also known as AP-4 complex, is a type of protein complex that plays a role in intracellular trafficking, specifically in the sorting and transport of proteins between the Golgi apparatus and endosomes. The AP-4 complex is composed of four subunits: beta-1, beta-2, gamma, and delta, with the delta subunit being one of its essential components.

The delta subunit of the AP-4 complex is encoded by the gene AP4D1 and is involved in the recognition and binding of specific sorting signals on protein cargo. Mutations in the AP4D1 gene have been associated with certain neurological disorders, such as hereditary spastic paraplegia and intellectual disability, highlighting the importance of this protein complex in proper brain function.

Adaptor Protein Complex 3 (APC3), also known as AP-3, is a type of adaptor protein complex that plays a crucial role in the sorting and trafficking of proteins within cells. It is composed of four subunits: delta, beta3A, mu3, and sigma3A. APC3 is primarily involved in the transport of proteins from the early endosomes to the lysosomes or to the plasma membrane. It also plays a role in the biogenesis of lysosome-related organelles such as melanosomes and platelet-dense granules. Mutations in the genes encoding for APC3 subunits have been associated with several genetic disorders, including Hermansky-Pudlak syndrome and Chediak-Higashi syndrome.

Adaptor Protein Complex 1 (AP-1) is a group of proteins that function as a complex to play a crucial role in the intracellular transport of various molecules, particularly in the formation of vesicles that transport cargo from one compartment of the cell to another. The AP-1 complex is composed of four subunits: γ, β1, μ1, and σ1. It is primarily associated with the trans-Golgi network and early endosomes, where it facilitates the sorting and packaging of cargo into vesicles for transport to various destinations within the cell. The AP-1 complex recognizes specific sorting signals on the membrane proteins and adaptor proteins, thereby ensuring the accurate delivery of cargo to the correct location. Defects in the AP-1 complex have been implicated in several human diseases, including neurological disorders and cancer.

Adaptor Protein Complex 2 (AP-2) is a protein complex that plays a crucial role in the formation of clathrin-coated vesicles, which are involved in intracellular trafficking and transport of membrane proteins and lipids. The AP-2 complex is composed of four subunits: alpha, beta, mu, and sigma, which form a heterotetrameric structure. It functions as a bridge between the clathrin lattice and the cytoplasmic domains of membrane proteins, such as transmembrane receptors, that are destined for endocytosis. The AP-2 complex recognizes specific sorting signals within the cytoplasmic tails of these membrane proteins, leading to their recruitment into forming clathrin-coated pits and subsequent internalization via clathrin-coated vesicles. This process is essential for various cellular functions, including receptor-mediated endocytosis, synaptic vesicle recycling, and membrane protein trafficking.

Adaptor Protein Complex 4 (AP-4) is a group of proteins that form a complex and play a crucial role in the intracellular trafficking of membrane proteins within eukaryotic cells. The AP-4 complex is composed of four subunits, namely, α-Adaptin, β2-Adaptin, Mu-Adaptin, and Sigmal-Adaptin4 (σ4A or σ4B).

The primary function of the AP-4 complex is to facilitate the sorting of proteins in the trans-Golgi network (TGN) and endosomes. It recognizes specific sorting signals present on the cytoplasmic tails of membrane proteins, recruits accessory proteins, and mediates the formation of transport vesicles that carry these proteins to their target destinations.

Mutations in genes encoding AP-4 complex subunits have been associated with several neurological disorders, including hereditary spastic paraplegia (HSP), mental retardation, and cerebral palsy. These genetic defects disrupt the normal functioning of the AP-4 complex, leading to aberrant protein trafficking and impaired neuronal development and function.

Adaptor protein complex subunits are proteins that combine to form adaptor protein complexes, which are essential components of intracellular transport vesicles. These complexes play a crucial role in recognizing and binding to specific cargo molecules, as well as interacting with coat proteins and membrane phospholipids to facilitate the formation and budding of transport vesicles from donor membranes.

There are five types of adaptor protein complexes, each consisting of several subunits: AP-1, AP-2, AP-3, AP-4, and AP-5. These subunits are named according to their molecular weights and the type of complex they form. For example, AP-1 consists of four subunits, including two large subunits (γ and β1 or β2), one medium subunit (μ1), and one small subunit (σ1).

The specific combination of subunits in each complex determines its function and localization within the cell. For instance, AP-1 is primarily involved in transport between the trans-Golgi network and endosomes, while AP-2 is responsible for clathrin-mediated endocytosis at the plasma membrane. Mutations in adaptor protein complex subunits have been linked to various human diseases, including neurological disorders and cancer.

The adaptor protein complex mu (AP-μ or AP-2) is a heterotetrameric complex that plays a crucial role in clathrin-mediated endocytosis, a process by which cells internalize various molecules from their external environment. The subunits of the AP-μ complex are:

1. AP2M1 (Adaptin-μ1): This is the μ subunit, which binds to the clathrin heavy chain and helps recruit it to the membrane during vesicle formation. It also plays a role in cargo recognition by interacting with sorting signals on transmembrane proteins.
2. AP2B1 (Adaptin-β1): This is the β subunit, which interacts with the μ and σ subunits to form the core of the complex. It also binds to accessory proteins that regulate endocytosis.
3. AP2S1 (Adaptin-σ1): This is the σ subunit, which helps stabilize the interaction between the μ and β subunits and contributes to cargo recognition by binding to specific sorting signals on transmembrane proteins.
4. AP2L1 (Adaptin-λ1): This is the λ subunit, which interacts with the α subunit of adaptor protein complex 1 (AP-1) and helps coordinate the trafficking of proteins between different endocytic compartments.

Together, these subunits form a complex that plays a central role in clathrin-mediated endocytosis by regulating the recruitment of clathrin and other accessory proteins to the membrane, as well as the recognition and sorting of cargo molecules for internalization.

Adaptor proteins play a crucial role in vesicular transport, which is the process by which materials are transported within cells in membrane-bound sacs called vesicles. These adaptor proteins serve as a bridge between vesicle membranes and cytoskeletal elements or other cellular structures, facilitating the movement of vesicles throughout the cell.

There are several different types of adaptor proteins involved in vesicular transport, each with specific functions and localizations within the cell. Some examples include:

1. Clathrin Adaptor Protein Complex (AP-1, AP-2, AP-3, AP-4): These complexes are responsible for recruiting clathrin to membranes during vesicle formation, which helps to shape and stabilize the vesicle. They also play a role in sorting cargo into specific vesicles.

2. Coat Protein Complex I (COPI): This complex is involved in the transport of proteins between the endoplasmic reticulum (ER) and the Golgi apparatus, as well as within the Golgi itself. COPI-coated vesicles are formed by the assembly of coatomer proteins around the membrane, which helps to deform the membrane into a vesicle shape.

3. Coat Protein Complex II (COPII): This complex is involved in the transport of proteins from the ER to the Golgi apparatus. COPII-coated vesicles are formed by the assembly of Sar1, Sec23/24, and Sec13/31 proteins around the membrane, which helps to select cargo and form a vesicle.

4. BAR (Bin/Amphiphysin/Rvs) Domain Proteins: These proteins are involved in shaping and stabilizing membranes during vesicle formation. They can sense and curve membranes, recruiting other proteins to help form the vesicle.

5. SNARE Proteins: While not strictly adaptor proteins, SNAREs play a critical role in vesicle fusion by forming complexes that bring the vesicle and target membrane together. These complexes provide the energy required for membrane fusion, allowing for the release of cargo into the target compartment.

Overall, adaptor proteins are essential components of the cellular machinery that regulates intracellular trafficking. They help to select cargo, deform membranes, and facilitate vesicle formation, ensuring that proteins and lipids reach their correct destinations within the cell.

Adaptor Protein Complex (AP) gamma subunits are a part of the AP complexes, which are large protein assemblies involved in intracellular trafficking of proteins and vesicles. The AP complexes are responsible for recognizing specific sorting signals on membrane proteins and facilitating the formation of transport vesicles.

There are four different types of AP complexes (AP-1, AP-2, AP-3, and AP-4) that contain distinct subunit compositions. The gamma subunits are common to two of these complexes: AP-1 and AP-3.

AP-1 is primarily associated with transport between the Golgi apparatus and endosomes, while AP-3 is involved in trafficking from early endosomes to lysosomes or related organelles. The gamma subunit of AP-1 is called γ-adaptin, and the gamma subunit of AP-3 is called μ3A or μ3B, depending on the specific isoform.

Mutations in these gamma subunits can lead to various human genetic disorders, such as Hermansky-Pudlak syndrome (HPS) and X-linked mental retardation (XLMR).

Adaptor Protein Complex (AP) beta subunits are structural proteins that play a crucial role in intracellular vesicle trafficking. They are part of the heterotetrameric AP complex, which is responsible for recognizing and binding to specific sorting signals on membrane cargo proteins, allowing for their packaging into transport vesicles.

There are four different types of AP complexes (AP-1, AP-2, AP-3, and AP-4), each with a unique set of subunits that confer specific functions. The beta subunit is a common component of all four complexes and is essential for their stability and function.

The beta subunit interacts with other subunits within the AP complex as well as with accessory proteins, such as clathrin, to form a coat around the transport vesicle. This coat helps to shape the vesicle and facilitate its movement between different cellular compartments.

Mutations in genes encoding AP beta subunits have been linked to various human diseases, including forms of hemolytic anemia, neurological disorders, and immunodeficiency.

Adaptor Protein Complex (AP) alpha subunits are a group of proteins that play a crucial role in intracellular trafficking, specifically in the formation and transport of vesicles within cells. There are four different AP complexes (AP-1, AP-2, AP-3, and AP-4), each with its own unique set of subunits, including an alpha subunit.

The AP-1 complex, for example, is involved in the transport of proteins between the Golgi apparatus and endosomes. Its alpha subunit, AP1A1 or AP1A2, helps to recognize specific sorting signals on protein cargo and facilitates the assembly of clathrin coats around vesicles.

Similarly, the AP-2 complex is involved in clathrin-mediated endocytosis at the plasma membrane, and its alpha subunit, AP2A1 or AP2A2, helps to recruit clathrin and other accessory proteins to form coated pits.

Mutations in genes encoding for AP complex subunits have been linked to various human diseases, including neurological disorders and cancer.

Leukocyte Adhesion Deficiency Syndrome (LAD) is a group of rare inherited disorders that affect the ability of white blood cells, specifically neutrophils, to adhere to and migrate into tissues, particularly those involved in immune responses. This results in recurrent bacterial and fungal infections starting in infancy.

There are three types of LAD, each caused by different genetic mutations:

1. LAD I: This is the most common and severe form, caused by a deficiency in the CD18 protein which is crucial for neutrophil adhesion. Symptoms include delayed separation of the umbilical cord, severe periodontal disease, and recurrent skin, lung and gastrointestinal infections.

2. LAD II: Also known as congenital disorder of glycosylation, type Ib, it is caused by a deficiency in the enzyme glucosyltransferase, leading to abnormal sugar chains on cell surfaces. Symptoms are similar to LAD I but less severe, and also include mental retardation and impaired growth.

3. LAD III: This is the least common form, caused by a defect in the integrin-linked kinase (ILK) gene. It results in a more complex phenotype with muscular and cardiac abnormalities, in addition to immune dysfunction.

Treatment typically involves prophylactic antibiotics, granulocyte-colony stimulating factor (G-CSF) to increase neutrophil counts, and sometimes bone marrow transplantation.

Complement activation is the process by which the complement system, a part of the immune system, is activated to help eliminate pathogens and damaged cells from the body. The complement system consists of a group of proteins that work together to recognize and destroy foreign substances.

Activation of the complement system can occur through three different pathways: the classical pathway, the lectin pathway, and the alternative pathway. Each pathway involves a series of proteolytic reactions that ultimately result in the formation of the membrane attack complex (MAC), which creates a pore in the membrane of the target cell, leading to its lysis and removal.

The classical pathway is typically activated by the binding of antibodies to antigens on the surface of a pathogen or damaged cell. The lectin pathway is activated by the recognition of specific carbohydrate structures on the surface of microorganisms. The alternative pathway can be spontaneously activated and serves as an amplification loop for both the classical and lectin pathways.

Complement activation plays a crucial role in the immune response, but uncontrolled or excessive activation can also lead to tissue damage and inflammation. Dysregulation of complement activation has been implicated in various diseases, including autoimmune disorders, inflammatory conditions, and neurodegenerative diseases.

Complement receptors are proteins found on the surface of various cells in the human body, including immune cells and some non-immune cells. They play a crucial role in the complement system, which is a part of the innate immune response that helps to eliminate pathogens and damaged cells from the body. Complement receptors bind to complement proteins or fragments that are generated during the activation of the complement system. This binding triggers various intracellular signaling events that can lead to diverse cellular responses, such as phagocytosis, inflammation, and immune regulation.

There are several types of complement receptors, including:

1. CR1 (CD35): A receptor found on erythrocytes, B cells, neutrophils, monocytes, macrophages, and glomerular podocytes. It functions in the clearance of immune complexes and regulates complement activation.
2. CR2 (CD21): Expressed mainly on B cells and follicular dendritic cells. It facilitates antigen presentation, B-cell activation, and immune regulation.
3. CR3 (CD11b/CD18, Mac-1): Present on neutrophils, monocytes, macrophages, and some T cells. It mediates cell adhesion, phagocytosis, and intracellular signaling.
4. CR4 (CD11c/CD18, p150,95): Expressed on neutrophils, monocytes, macrophages, and dendritic cells. It is involved in cell adhesion, phagocytosis, and intracellular signaling.
5. C5aR (CD88): Found on various immune cells, including neutrophils, monocytes, macrophages, mast cells, eosinophils, and dendritic cells. It binds to the complement protein C5a and mediates chemotaxis, degranulation, and inflammation.
6. C5L2 (GPR77): Present on various cell types, including immune cells. Its function is not well understood but may involve regulating C5a-mediated responses or acting as a receptor for other ligands.

These receptors play crucial roles in the immune response and inflammation by mediating various functions such as chemotaxis, phagocytosis, cell adhesion, and intracellular signaling. Dysregulation of these receptors has been implicated in several diseases, including autoimmune disorders, infections, and cancer.

The complement system is a group of proteins found in the blood and on the surface of cells that when activated, work together to help eliminate pathogens such as bacteria, viruses, and fungi from the body. The proteins are normally inactive in the bloodstream. When they encounter an invading microorganism or foreign substance, a series of reactions take place leading to the activation of the complement system. Activation results in the production of effector molecules that can punch holes in the cell membranes of pathogens, recruit and activate immune cells, and help remove debris and dead cells from the body.

There are three main pathways that can lead to complement activation: the classical pathway, the lectin pathway, and the alternative pathway. Each pathway involves a series of proteins that work together in a cascade-like manner to amplify the response and generate effector molecules. The three main effector molecules produced by the complement system are C3b, C4b, and C5b. These molecules can bind to the surface of pathogens, marking them for destruction by other immune cells.

Complement proteins also play a role in the regulation of the immune response. They help to prevent excessive activation of the complement system, which could damage host tissues. Dysregulation of the complement system has been implicated in a number of diseases, including autoimmune disorders and inflammatory conditions.

In summary, Complement System Proteins are a group of proteins that play a crucial role in the immune response by helping to eliminate pathogens and regulate the immune response. They can be activated through three different pathways, leading to the production of effector molecules that mark pathogens for destruction. Dysregulation of the complement system has been linked to various diseases.

Complement C3 is a protein that plays a central role in the complement system, which is a part of the immune system that helps to clear pathogens and damaged cells from the body. Complement C3 can be activated through three different pathways: the classical pathway, the lectin pathway, and the alternative pathway. Once activated, it breaks down into two fragments, C3a and C3b.

C3a is an anaphylatoxin that helps to recruit immune cells to the site of infection or injury, while C3b plays a role in opsonization, which is the process of coating pathogens or damaged cells with proteins to make them more recognizable to the immune system. Additionally, C3b can also activate the membrane attack complex (MAC), which forms a pore in the membrane of target cells leading to their lysis or destruction.

In summary, Complement C3 is an important protein in the complement system that helps to identify and eliminate pathogens and damaged cells from the body through various mechanisms.

Complement receptor 3b (CR3b or CD11b/CD18) is not a medical definition itself, but I can provide you with the relevant information regarding this term.

Complement receptor 3 (CR3) is a heterodimeric receptor consisting of two subunits, CD11b (also known as Mac-1 or CR3 alpha) and CD18 (also known as beta2 integrin). There are two forms of the CD11b/CD18 heterodimer: CR3a (CD11b/CD18) and CR3b (CD11b/CD18'). The difference between these two forms lies in the conformation of the CD11b subunit.

Complement receptor 3b (CR3b or CD11b/CD18') is a less common form of the CR3 receptor, which is primarily expressed on myeloid cells such as monocytes, macrophages, and neutrophils. CR3b has a higher affinity for complement component C3b and its fragments iC3b and C3dg compared to CR3a.

CR3b plays a role in various immune functions, including:

1. Phagocytosis: Binding of C3b or its fragments to CR3b facilitates the recognition and uptake of opsonized pathogens by phagocytes.
2. Adhesion: The integrin component of CR3b mediates cell-cell and cell-matrix interactions, contributing to leukocyte migration and recruitment to sites of inflammation or infection.
3. Intracellular signaling: Activation of CR3b can lead to intracellular signaling events that modulate immune responses, such as the release of pro-inflammatory cytokines and reactive oxygen species.

In summary, Complement receptor 3b (CR3b or CD11b/CD18') is a less common form of CR3 primarily expressed on myeloid cells that binds complement component C3b and its fragments with high affinity, mediating phagocytosis, adhesion, and intracellular signaling.

CD18 is a type of protein called an integrin that is found on the surface of many different types of cells in the human body, including white blood cells (leukocytes). It plays a crucial role in the immune system by helping these cells to migrate through blood vessel walls and into tissues where they can carry out their various functions, such as fighting infection and inflammation.

CD18 forms a complex with another protein called CD11b, and together they are known as Mac-1 or CR3 (complement receptor 3). This complex is involved in the recognition and binding of various molecules, including bacterial proteins and fragments of complement proteins, which help to trigger an immune response.

CD18 has been implicated in a number of diseases, including certain types of cancer, inflammatory bowel disease, and rheumatoid arthritis. Mutations in the gene that encodes CD18 can lead to a rare disorder called leukocyte adhesion deficiency (LAD) type 1, which is characterized by recurrent bacterial infections and impaired wound healing.
