Post Translational Modifications
Lysines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated. The modified lysines can be O-glycosylated. Contains 4-hydroxyproline (Probable). Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains. Contains 3-hydroxyproline. This modification occurs on the first proline residue in the sequence motif Gly-Pro-Hyp, where Hyp is 4-hydroxyproline. Type IV collagens contain numerous cysteine residues which are involved in inter- and intramolecular disulfide bonding. 12 of these, located in the NC1 domain, are conserved in all known type IV collagens. The trimeric structure of the NC1 domains is stabilized by covalent bonds (sulfilimine cross-links) between Lys and Met residues. These cross-links are important for the mechanical stability of the basement membrane. Sulfilimine cross-link is catalyzed by PXDN. Proteolytic processing produces the C-terminal NC1 peptide, arresten.
Function
Type IV collagen is the major structural component of glomerular basement membranes (GBM), forming a 'chicken-wire' meshwork together with laminins, proteoglycans and entactin/nidogen. Arresten, comprising the C-terminal NC1 domain, inhibits angiogenesis and tumor formation. The C-terminal half is found to possess the anti-angiogenic activity. Specifically inhibits endothelial cell proliferation, migration and tube formation.
