  • The integrin tails have no intrinsic kinase activity but rather serve as a site for the docking of various kinases and related adaptor proteins that comprise focal adhesions. (thno.org)
  • Agrin-like glycoproteins and proteins with sugar-binding domains are also predominant. (biomedcentral.com)
  • The predominant form of the protein is comprised of two alpha1(IV) subunits and one alpha2(IV) subunit, however, at least six different alpha subunits can be incorporated into the heterotrimer. (lookformedical.com)
  • Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors. (novusbio.com)
  • We identified a total of 102 OM proteins, 52 are found in the two red coral biominerals with scleritin being the most abundant protein in each fraction. (biomedcentral.com)
  • A fibrillar collagen consisting of three identical alpha1(III) chains that is widely distributed in many tissues containing COLLAGEN TYPE I. It is particularly abundant in BLOOD VESSELS and may play a role in tissues with elastic characteristics. (lookformedical.com)
  • Comparison of the mechanisms that govern the production of calcium carbonate (CaCO 3 ) biominerals in hexacorallians (scleractinians) and octocorallians is thus expected to shed light on the conservation of the protein toolkit used by these organisms for making their biocalcification.

  • Collagen receptors are cell surface receptors that modulate signal transduction between cells and the EXTRACELLULAR MATRIX. (lookformedical.com)
  • Cytokines bind to their receptors, activating signal transduction pathways such as adenylate cyclase/cAMP, phospholipase C/inositol trisphosphate, and Ca 2+ and tyrosine kinases. (biomedcentral.com)
  • The oocyte is loaded with maternal mRNAs and proteins that control the cell maintenance and fate and the formation of the body plan prior to the onset of zygotic genome expression [ 3 , 4 ]. (biomedcentral.com)
  • They are found in many cell types and are involved in the maintenance and regulation of cell shape and behavior, including PLATELET ACTIVATION and aggregation, through many different signaling pathways and differences in their affinities for collagen isoforms. (lookformedical.com)
  • Other profibrotic, collagen synthesis stimulating cytokines include endothelin, interleukin (IL)-1 and mast cell tryptase. (biomedcentral.com)
  • A hallmark of events observed during segmentation was the induction of multiple transcription factors, including a large group of homeobox proteins in pace with decay of a large fraction of maternal transcripts. (biomedcentral.com)
  • Collagen type IV molecules assemble to form a sheet-like network which is involved in maintaining the structural integrity of basement membranes. (lookformedical.com)
  • The alpha subunits of collagen type VI assemble into antiparallel, overlapping dimers which then align to form tetramers. (lookformedical.com)
  • Several forms of collagen type V exist depending upon the composition of the subunits that form the trimer. (lookformedical.com)
  • The C-terminal end of the alpha1 chain of collagen type XVIII contains the ENDOSTATIN peptide, which can be released by proteolytic cleavage. (lookformedical.com)
  • Collagen type XI is heterotrimer containing alpha1(XI), alpha2(XI) and alpha3(XI) subunits. (lookformedical.com)
  • The neurotrophin family is comprised of at least four proteins including NGF, BDNF, NT-3, and NT-4/5. (novusbio.com)
  • Contrary to reef building corals, the red coral organic matrix possesses a large number of collagen-like proteins. (biomedcentral.com)
  • The inferred regulatory function of these OM proteins suggests that the difference between the two biominerals is due to the modeling of the matrix network, rather than the presence of specific structural components. (biomedcentral.com)
  • A non-fibrillar collagen that forms a network of MICROFIBRILS within the EXTRACELLULAR MATRIX of CONNECTIVE TISSUE. (lookformedical.com)
  • 13-14 kDa, under reducing conditions. (novusbio.com)
  • This classification was based on the notion that "collagen" was equivalent to "connective tissue", but with the present recognition of the different types of collagen and the aggregates derived from them as distinct entities, the term "collagen diseases" now pertains exclusively to those inherited conditions in which the primary defect is at the gene level and affects collagen biosynthesis, post-translational modification, or extracellular processing directly.
