Lack of cytosolic and transmembrane domains of type XIII collagen results in progressive myopathy. (1/11)
Type XIII collagen is a type II transmembrane protein found at many sites of cell adhesion in tissues. Homologous recombination was used to generate a transgenic mouse line (Col13a1(N/N)) that expresses N-terminally altered type XIII collagen molecules lacking the short cytosolic and transmembrane domains but retaining the large collagenous ectodomain. The mutant molecules were correctly transported to focal adhesions in cultured fibroblasts derived from the Col13a1(N/N) mice, but the cells showed decreased adhesion when plated on type IV collagen. These mice were viable and fertile, and in immunofluorescence stainings the mutant protein was located in adhesive tissue structures in the same manner as normal alpha1(XIII) chains. In immunoelectron microscopy of wild-type mice type XIII collagen was detected at the plasma membrane of skeletal muscle cells whereas in the mutant mice the protein was located in the adjacent extracellular matrix. Affected skeletal muscles showed abnormal myofibers with a fuzzy plasma membrane-basement membrane interphase along the muscle fiber and at the myotendinous junctions, disorganized myofilaments, and streaming of z-disks. The findings were progressive and the phenotype was aggravated by exercise. Thus type XIII collagen seems to participate in the linkage between muscle fiber and basement membrane, a function impaired by lack of the cytosolic and transmembrane domains.

Type XIII collagen consists of a short N-terminal intracellular domain, a transmembrane domain, and a collagenous ectodomain, and it is found at many sites of cell adhesion. We report on the characterization of recombinant type XIII collagen. The shed ectodomain was purified from insect cell culture medium and shown to form 240-kDa trimers with a T(m) of 42 degrees C. Correct chain association into a triple-helical conformation was confirmed by limited pepsin digestion and CD spectroscopy. Rotary shadowing electron microscopy of the ectodomain revealed it to be a 150-nm rod with two flexible hinges separating 31-, 52-, and 68-nm portions. The rods represent the collagenous domains 1-3, and the hinges coincide with the non-collagenous domains 2 and 3. By using surface plasmon resonance analysis, the ectodomain showed interaction with immobilized fibronectin, nidogen-2, and perlecan with K(D) values in the nanomolar range. The binding sites of type XIII collagen for fibronectin were localized to the collagenous domains, whereas the binding activities for nidogen-2 and perlecan resided in the pepsin-sensitive portions of the ectodomain. Furthermore, the ectodomain bound significantly to heparin, which also inhibited shedding of the ectodomain in insect cell cultures. The results reveal that type XIII collagen is notably distinct in its structure compared with other cell-surface proteins, and the in vitro binding with fibronectin, heparin, and two basement membrane components is indicative of multiple cell-matrix interactions in which this ubiquitously expressed protein participates. (+info)Type XIII collagen and some other transmembrane collagens contain two separate coiled-coil motifs, which may function as independent oligomerization domains. (3/11)
Type XIII collagen is a homotrimeric transmembrane collagen composed of a short intracellular domain, a single membrane-spanning region, and an extracellular ectodomain with three collagenous domains (COL1-3) separated by short non-collagenous domains (NC1-4). Several collagenous transmembrane proteins have been found to harbor a conserved sequence next to their membrane-spanning regions, and in the case of type XIII collagen this sequence has been demonstrated to be important for chain association. We show here that this 21-residue sequence is necessary but not sufficient for NC1 association. Furthermore, the NC1 association region was predicted to form an alpha-helical coiled-coil structure, which may already begin at the membrane-spanning region, as is also predicted for the related collagen types XXIII and XXV. Interestingly, a second coiled-coil structure is predicted to be located in the NC3 domain of type XIII collagen and in the corresponding domains of types XXIII and XXV. It is found experimentally that the absence of the NC1 coiled-coil domain leads to a lack of disulfide-bonded trimers and misfolding of the membrane-proximal collagenous domain COL1, whereas the COL2 and COL3 domains are correctly folded. We suggest that the NC1 coiled-coil domain is important for association of the N-terminal part of the type XIII collagen alpha chains, whereas the NC3 coiled-coil domain is implicated in the association of the C-terminal part of the molecule. All in all, we propose that two widely separated coiled-coil domains of type XIII and related collagens function as independent oligomerization domains participating in the folding of distinct areas of the molecule. (+info)The shed ectodomain of type XIII collagen affects cell behaviour in a matrix-dependent manner. (4/11)
Transmembrane type XIII collagen resides in adhesive structures of cells and tissues, and has therefore been implicated in cell adhesion and in adhesion-dependent cell functions. This collagen also exists as a soluble protein in the pericellular matrix, as the ectodomain is released from the plasma membrane by proteolytic cleavage. Analysis with various protease inhibitors led to confirmation of the furin family of proprotein convertases as the protease group responsible for the shedding of the ectodomain, cleaving at a site conforming to the consensus sequence for the proprotein convertases at the stem of the ectodomain. Both the trans -Golgi network and the plasma membrane were used as cleavage locations. Mammalian cells employed various intracellular mechanisms to modulate shedding of the ectodomain, all resulting in a similar cleavage event. Cell detachment from the underlying substratum was also found to augment the excision. The released ectodomain rendered the pericellular surroundings less supportive of cell adhesion, migration and proliferation, as seen specifically on a vitronectin substratum. Type XIII collagen ectodomain shedding thus resulted in the formation of a soluble, biologically active molecule, which eventually modulated cell behaviour in a reciprocal and substratum-specific manner. The dual existence of membrane-bound and soluble variants widens our biological understanding of type XIII collagen. (+info)The shed ectodomain of type XIII collagen associates with the fibrillar fibronectin matrix and may interfere with its assembly in vitro. (5/11)
Type XIII collagen is a transmembrane collagen, which is known to exist also as a soluble variant due to ectodomain shedding. Earlier studies with the recombinant ectodomain have shown it to interact in vitro with a number of extracellular matrix proteins, e.g. Fn (fibronectin). In view of its strong binding to Fn, we examined in the present study whether the released soluble ectodomain can bind to the fibrillar Fn matrix under cell-culture conditions and, if so, influence its assembly. In this study, we demonstrate that the type XIII collagen ectodomain of mammalian cells can associate with Fn fibres and may eventually hamper incorporation of the fibrillar Fn meshwork. The association between type XIII collagen and Fn was implicated to be mediated by the C-terminal end of type XIII collagen and the N-terminal end of Fn. The results presented here imply that the shedding of the type XIII collagen ectodomain results in a biologically active molecule capable of remodelling the structure of the pericellular matrix. (+info)Modulation of the cellular cholesterol level affects shedding of the type XIII collagen ectodomain. (6/11)
Type XIII collagen is a transmembrane protein that also exists as a soluble extracellular variant because of ectodomain shedding by proprotein convertases. Because ectodomain shedding in a growing number of transmembrane proteins has recently been shown to be dependent on their localization in cholesterol-enriched detergent-resistant membrane microdomains, this work aimed at analyzing this aspect of type XIII collagen ectodomain processing. In HT-1080 cells type XIII collagen and its cleaving proprotein convertase furin localized partially in detergent-resistant cholesterol-containing membrane microdomains. Disruption of these domains by lowering either the level or availability of the cellular cholesterol reduced ectodomain shedding, implying that, in such membrane domains correct cholesterol level is important for the regulation of type XIII collagen ectodomain processing. In addition, we show here that ectodomain of type XIII collagen is also shed intracellularly. HT-1080 cells released vesicles from the Golgi apparatus, which contained only the cleaved variant. Intracellular processing and the subsequent entry of the cleaved ectodomain into the vesicles was totally blocked by inhibition of the proprotein convertase function by cell-permeable chloromethylketone, but not with cell-impermeable alpha1-antitrypsin Portland. This supports the hypothesis of type XIII collagen ectodomain also being cleaved intracellularly in the Golgi and suggests that the intracellular cleavage may act as a gating event in the vesicle-mediated ectodomain secretion. (+info)Cleavage and oligomerization of gliomedin, a transmembrane collagen required for node of ranvier formation. (7/11)
Gliomedin, which has been implicated as a major player in genesis of the nodes of Ranvier, contains two collagenous domains and an olfactomedin-like domain and belongs to the group of type II transmembrane collagens that includes collagens XIII and XVII and ectodysplasin A. One characteristic of this protein family is that constituent proteins can exist in both transmembrane and soluble forms. Recently, gliomedin expressed at the tips of Schwann cell microvilli was found to bind axonal adhesion molecules neurofascin and NrCAM in interactions essential for Na(+)-channel clustering at the nodes of Ranvier in myelinating peripheral nerves. Interestingly, exogenously added olfactomedin domain was found to have the same effect as intact gliomedin. Here we analyze the tissue form of gliomedin and demonstrate that the molecule not only exists as full-length gliomedin but also as a soluble form shed from the cell surface in a furin-dependent manner. In addition, gliomedin can be further proteolytically processed by bone morphogenetic protein 1/Tolloid-like enzymes, resulting in release of the olfactomedin domain from the collagen domains. Interestingly, the later cleavage induces formation of higher order, insoluble molecular aggregates that may play important roles in Na(+)-channel clustering. (+info)The role of disulfide bonds and alpha-helical coiled-coils in the biosynthesis of type XIII collagen and other collagenous transmembrane proteins. (8/11)
Type XIII collagen is a type II transmembrane protein with three collagenous (COL1-3) and four noncollagenous domains (NC1-4). The human alpha1(XIII) chain contains altogether eight cysteine residues. We introduced point mutations to six of the most N-terminal cysteine residues, and we show here that the two cysteines 117 and 119 at the end of the N-terminal noncollagenous domain (NC1) are responsible for linking the three alpha1(XIII) chains together by means of interchain disulfide bonds. In addition, the intracellular and transmembrane domains have an impact on trimer formation, whereas the cysteines in the transmembrane domain and the COL1, the NC2, and the C-terminal NC4 domains do not affect trimer formation. We also suggest that the first three noncollagenous domains (NC1-3) harbor repeating heptad sequences typical of alpha-helical coiled-coils, whereas the conserved NC4 lacks a coiled-coil probability. Prevention of the coiled-coil conformation in the NC3 domain is shown here to result in labile type XIII collagen molecules. Furthermore, a new subgroup of collagenous transmembrane proteins, the Rattus norvegicus, Drosophila melanogaster, and Caenorhabditis elegans colmedins, is enlarged to contain also Homo sapiens collomin, and Pan troglodytes, Mus musculus, Tetraodon nigroviridis, and Dano rerio proteins. We suggest that there is a structurally varied group of collagenous transmembrane proteins whose biosynthesis is characterized by a coiled-coil motif following the transmembrane domain, and that these trimerization domains appear to be associated with each of the collagenous domains. In the case of type XIII collagen, the trimeric molecule has disulfide bonds at the junction of the NC1 and COL1 domains, and the type XIII collagen-like molecules (collagen types XXIII and XXV) and the colmedins are similar in that they all have a pair of cysteines in the same location. Moreover, furin cleavage at the NC1 domain can be expected in most of the proteins. (+info)Collagen Type XIII is a type of protein that is found in the extracellular matrix of connective tissues in the human body. It is a heterotrimeric protein composed of three subunits: α1(XIII), α2(XIII), and β1(XIII). Collagen Type XIII plays a crucial role in the stability and integrity of the extracellular matrix, particularly in areas of high mechanical stress such as tendons, ligaments, and skin. It is also involved in the regulation of cell adhesion and migration, and has been implicated in the development and progression of various diseases, including fibrosis, osteoarthritis, and skin disorders. In the medical field, Collagen Type XIII is being studied as a potential target for the development of new treatments for these conditions. Additionally, it is being used as a biomarker to diagnose and monitor the progression of certain diseases.
Factor XIII, also known as fibrin-stabilizing factor or tenase factor, is a blood clotting protein that plays a crucial role in the formation and stability of blood clots. It is a heterotetramer composed of two A subunits and two B subunits, and it is synthesized in the liver and circulates in the bloodstream. Factor XIII is activated by thrombin, a protease enzyme that is generated during the clotting cascade. Once activated, Factor XIII catalyzes the formation of a covalent bond between two adjacent fibrin molecules, which helps to stabilize the fibrin meshwork and prevent it from being broken down by proteases. This is an important step in the final stages of blood clotting, as it ensures that the clot remains intact and prevents excessive bleeding. Factor XIII deficiency, also known as hemophilia C, is a rare genetic disorder characterized by a deficiency or dysfunction of Factor XIII. This can lead to an increased risk of bleeding and bruising, as well as prolonged bleeding after injury or surgery. Treatment for Factor XIII deficiency typically involves replacement therapy with Factor XIII concentrate.
Collagen is a protein that is found in the extracellular matrix of connective tissues throughout the body. It is the most abundant protein in the human body and is responsible for providing strength and support to tissues such as skin, bones, tendons, ligaments, and cartilage. In the medical field, collagen is often used in various medical treatments and therapies. For example, it is used in dermal fillers to plump up wrinkles and improve skin texture, and it is also used in wound healing to promote tissue regeneration and reduce scarring. Collagen-based products are also used in orthopedic and dental applications, such as in the production of artificial joints and dental implants. In addition, collagen is an important biomarker for various medical conditions, including osteoporosis, rheumatoid arthritis, and liver disease. It is also used in research to study the mechanisms of tissue repair and regeneration, as well as to develop new treatments for various diseases and conditions.
Collagen Type I is a protein that is found in the extracellular matrix of connective tissues throughout the body. It is the most abundant type of collagen, making up about 80-90% of the total collagen in the body. Collagen Type I is a strong, flexible protein that provides support and structure to tissues such as skin, bones, tendons, ligaments, and cartilage. It is also involved in wound healing and tissue repair. In the medical field, Collagen Type I is often used in various medical applications such as tissue engineering, regenerative medicine, and cosmetic surgery. It is also used in some dietary supplements and skincare products.
Factor XIII deficiency is a rare bleeding disorder that affects the blood's ability to clot properly. It is caused by a deficiency or absence of Factor XIII, a protein that plays a crucial role in the blood clotting process. Factor XIII deficiency can be inherited in an autosomal recessive pattern, meaning that an individual must inherit two copies of the defective gene (one from each parent) to develop the condition. Alternatively, it can be acquired as a result of certain medical conditions or treatments, such as liver disease, cancer, or chemotherapy. Symptoms of Factor XIII deficiency may include easy bruising, prolonged bleeding after injury or surgery, and heavy menstrual bleeding in women. In severe cases, it can lead to life-threatening bleeding episodes, such as internal bleeding in the brain or abdomen. Treatment for Factor XIII deficiency typically involves replacement therapy with Factor XIII concentrate, which can help to restore normal clotting function. In some cases, surgery or other interventions may be necessary to manage bleeding episodes.
Furin is a protease enzyme that is found in many different types of cells throughout the body. It is a member of the subtilisin family of proteases and is known to play a role in the activation of certain proteins, including the spike protein of the SARS-CoV-2 virus, which causes COVID-19. In the context of COVID-19, furin has been shown to play a role in the ability of the virus to enter and infect cells. The spike protein of the virus contains a cleavage site that is recognized by furin, allowing the protein to be cleaved and activated. This activation is necessary for the virus to enter cells and replicate. Furin inhibitors are being investigated as potential treatments for COVID-19, as they may be able to block the activation of the spike protein and prevent the virus from infecting cells. However, more research is needed to fully understand the role of furin in the pathogenesis of COVID-19 and to determine the safety and efficacy of furin inhibitors as treatments.
Collagen Type III is a protein that is a major component of the extracellular matrix in connective tissues throughout the body. It is the most abundant type of collagen in the skin, and it plays a critical role in maintaining the skin's elasticity and strength. Collagen Type III is also found in other tissues, including blood vessels, tendons, ligaments, and bones. In the medical field, Collagen Type III is often studied in relation to various diseases and conditions, including skin disorders, cardiovascular disease, and osteoporosis. It is also used in various medical treatments, such as wound healing and tissue engineering.
Collagen Type IV is a type of protein that is found in the basement membrane of many tissues in the human body. It is a major component of the extracellular matrix, which is the network of proteins and other molecules that provide structural support to cells and tissues. Collagen Type IV is particularly important in the formation and maintenance of blood vessels, the lungs, and the kidneys. It is also involved in the development of many different types of cancer, and changes in the expression of this protein have been linked to a number of different diseases and conditions.
Collagen Type II is a protein that is primarily found in the cartilage of joints, such as the knee and hip. It is the most abundant protein in the human body and is responsible for providing strength and flexibility to the cartilage. Collagen Type II is also found in the vitreous humor of the eye and in the skin. In the medical field, Collagen Type II is often used in the treatment of osteoarthritis, a degenerative joint disease that affects the cartilage in the joints. It is also used in cosmetic procedures to improve skin elasticity and reduce the appearance of wrinkles.
Pepsin A is a digestive enzyme that is produced in the lining of the stomach. It is responsible for breaking down proteins into smaller peptides and amino acids, which can then be absorbed by the body. Pepsin A is activated by hydrochloric acid, which is also produced in the stomach, and is typically secreted in an inactive form called pepsinogen. Once it is activated, pepsin A has a pH optimum of around 2, which is the acidic environment of the stomach. It is an important part of the digestive process and is involved in the breakdown of many different types of proteins, including those found in meat, dairy products, and eggs.
Collagen Type V is a protein that is found in the extracellular matrix of connective tissues in the human body. It is a component of the fibrillar collagen network, which provides strength and support to tissues such as skin, tendons, ligaments, and bone. Collagen Type V is a heterotrimeric protein, meaning that it is composed of three different chains of collagen, called alpha chains. The three alpha chains of collagen Type V are called alpha 1(V), alpha 2(V), and alpha 3(V). Collagen Type V is known for its unique triple helical structure, which is formed by the winding of the three alpha chains around each other. This structure gives collagen its strength and flexibility. In addition to its structural role in connective tissues, collagen Type V has also been implicated in a number of biological processes, including cell signaling, tissue development, and wound healing. It is also involved in the regulation of blood vessel formation and the development of blood clots. Research has suggested that collagen Type V may play a role in the development of certain diseases, including osteoporosis, atherosclerosis, and certain types of cancer. As a result, there is ongoing interest in understanding the function of collagen Type V and developing therapies that target this protein.
Fibrillar collagens are a type of collagen protein that are found in the extracellular matrix of connective tissues throughout the body. They are the most abundant protein in the human body and play a crucial role in maintaining the structural integrity of tissues such as skin, tendons, ligaments, and bones. Fibrillar collagens are characterized by their long, fibrous structure and are composed of three protein subunits, called alpha chains, that are coiled together to form a triple helix. There are several different types of fibrillar collagens, including types I, II, III, IV, V, and VI, each of which has a unique structure and function. Type I fibrillar collagen is the most common type and is found in the skin, bones, tendons, and ligaments. It provides strength and flexibility to these tissues and is essential for maintaining their structural integrity. Type II fibrillar collagen is found in the cartilage of joints and is responsible for its elasticity and ability to withstand compression. Type III fibrillar collagen is found in the skin, blood vessels, and other connective tissues and plays a role in wound healing and tissue repair.
Collagen Type VI is a protein that is found in the extracellular matrix of connective tissues in the body. It is a major component of the basement membrane, which is a thin layer of connective tissue that separates epithelial cells from underlying connective tissue. Collagen Type VI is also found in other tissues, such as blood vessels, tendons, and ligaments. In the medical field, Collagen Type VI is of interest because it is involved in a number of diseases and conditions. For example, mutations in the COL6A1 gene, which encodes the alpha 1 chain of Collagen Type VI, can cause a group of inherited disorders known as Ullrich congenital muscular dystrophy (UCMD) and Bethlem myopathy. These disorders are characterized by muscle weakness and wasting, as well as abnormalities in the skin and other connective tissues. Collagen Type VI is also being studied in the context of other diseases, such as cancer and fibrosis. In cancer, Collagen Type VI has been shown to play a role in tumor growth and invasion, and it may be a potential target for cancer therapy. In fibrosis, Collagen Type VI is thought to contribute to the formation of scar tissue, which can cause organ dysfunction and other complications.
