Characterized by the fine fibrils in the epithelial cells.Cell adhesionAdherens junctionDown syndrome cell adhesion molecule like 1: Down syndrome cell adhesion molecule like 1 is a protein in humans that is encoded by the DSCAML1 gene.Extremophile: An extremophile (from Latin meaning "extreme" and Greek () meaning "love") is an organism that thrives in physically or geochemically extreme conditions that are detrimental to most life on Earth. In contrast, organisms that live in more moderate environments may be termed mesophiles or neutrophiles.ARMCX5: ARMCX5 is an armadillo repeat–containing protein that is encoded by the X-linked ARMCX5 gene. It is conserved only in Eutheria, a specific group of placental mammals, but no further back in evolutionary time.Skin fragility syndrome: Skin fragility syndrome (also known as "Plakophilin 1 deficiency") is a cutaneous condition characterized by trauma-induced blisters and erosions.FERM domain: In molecular biology, the FERM domain (F for 4.1 protein, E for ezrin, R for radixin and M for moesin) is a widespread protein module involved in localising proteins to the plasma membrane.Coles PhillipsProximity ligation assay: Proximity ligation assay (in situ PLA) is a technology that extends the capabilities of traditional immunoassays to include direct detection of proteins, protein interactions and modifications with high specificity and sensitivity. Protein targets can be readily detected and localized with single molecule resolution and objectively quantified in unmodified cells and tissues.Protein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.PemphigusReceptor tyrosine phosphatase: Receptor tyrosine phosphatase is a type of Enzyme-linked receptor.CytoskeletonVinculin: In mammalian cells, vinculin is a membrane-cytoskeletal protein in focal adhesion plaques that is involved in linkage of integrin adhesion molecules to the actin cytoskeleton. Vinculin is a cytoskeletal protein associated with cell-cell and cell-matrix junctions, where it is thought to function as one of several interacting proteins involved in anchoring F-actin to the membrane.Radiobinding assay: A radiobinding assay is a method of detecting and quantifying antibodies targeted towards a specific antigen. As such, it can be seen as the inverse of radioimmunoassay, which quantifies an antigen by use of corresponding antibodies.Actin remodeling of neurons: Actin remodeling is a biochemical process in cells. In the actin remodeling of neurons, the protein actin is part of the process to change the shape and structure of dendritic spines.Cell polarity: Polarity}}Squamous epithelial cell: In anatomy, squamous epithelium (squama- + -ous) is that whose outermost (apical) layer consists of thin, flat cells called squamous epithelial cells. The epithelium may be composed of one layer of these cells, in which case it is referred to as simple squamous epithelium, or it may possess multiple layers, referred to then as stratified squamous epithelium.Phosphoprotein: A phosphoprotein is a protein that is posttranslationally modified by the attachment of either a single phosphate group, or a complex molecule such as 5'-phospho-DNA, through a phosphate group. The target amino acid is usually serine, threonine, or tyrosine residues (mostly in eukaryotes), or aspartic acid or histidine residues (mostly in prokaryotes).RNA transfection: RNA transfection is the process of deliberately introducing RNA into a living cell. RNA can be purified from cells after lysis or synthesized from free nucleotides either chemically, or enzymatically using an RNA polymerase to transcribe a DNA template.Haptotaxis: Haptotaxis (from Greek ἅπτω (hapto, "touch, fasten") and τάξις (taxis, "arrangement, order")) is the directional motility or outgrowth of cells, e.g.Vibronectin: Vibronectin is an extracellular matrix protein. It is an adhesion molecule in the integrin family.Symmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.Keratinocyte: A keratinocyte is the predominant cell type in the epidermis, the outermost layer of the skin, constituting 90% of the cells found there.Relapsing linear acantholytic dermatosis: Relapsing linear acantholytic dermatosis is a cutaneous condition characterized by relapsing linear erosions and crusting, histologically identical to Hailey–Hailey disease. It is not to be confused with transient acantholytic dermatosis.Protoplasm: Protoplasm is the living content of a cell that is surrounded by a plasma membrane. It is a general term for the cytoplasm.BRCT domainImmunostaining: Immunostaining is a general term in biochemistry that applies to any use of an antibody-based method to detect a specific protein in a sample. The term immunostaining was originally used to refer to the immunohistochemical staining of tissue sections, as first described by Albert Coons in 1941.Cell membraneMechanobiology: Mechanobiology is an emerging field of science at the interface of biology and engineering. It focuses on the way that physical forces and changes in cell or tissue mechanics contribute to development, physiology, and disease.Synaptophysin: Synaptophysin, also known as the major synaptic vesicle protein p38, is a protein that in humans is encoded by the SYP gene.Matrix model: == Mathematics and physics ==Chemically induced dimerization: Chemically Induced Dimerization (CID) is a biological mechanism in which two proteins bind only in the presence of a certain small molecule, enzyme or other dimerizing agent. Genetically engineered CID systems are used in biological research to control protein localization, to manipulate signalling pathways and to induce protein activation.Rho family of GTPases: The Rho family of GTPases is a family of small (~21 kDa) signaling G proteins, and is a subfamily of the Ras superfamily. The members of the Rho GTPase family have been shown to regulate many aspects of intracellular actin dynamics, and are found in all eukaryotic kingdoms, including yeasts and some plants.Calcium signaling: Calcium ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.Membrane protein: Membrane proteins are proteins that interact with biological membranes. They are one of the common types of protein along with soluble globular proteins, fibrous proteins, and disordered proteins.DNA binding site: DNA binding sites are a type of binding site found in DNA where other molecules may bind. DNA binding sites are distinct from other binding sites in that (1) they are part of a DNA sequence (e.Silent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.CS-BLASTIntermediate filament: Intermediate filaments (IFs) are cytoskeletal components found in the cells of many animal species.Karabinos, Anton, Dieter Riemer, Andreas Erber, and Klaus Weber.
