タンパク質の説明:
This gene encodes a type IV collagen alpha protein. Type IV collagen proteins are integral components of basement membranes. This gene shares a bidirectional promoter with a paralogous gene on the opposite strand. The protein consists of an amino-terminal 7S domain,a triple-helix forming collagenous domain,and a carboxy-terminal non-collagenous domain. It functions as part of a heterotrimer and interacts with other extracellular matrix components such as perlecans,proteoglycans,and laminins. In addition,proteolytic cleavage of the non-collagenous carboxy-terminal domain results in a biologically active fragment known as arresten,which has anti-angiogenic and tumor suppressor properties. Mutations in this gene cause porencephaly,cerebrovascular disease,and renal and muscular defects. Alternative splicing results in multiple transcript variants.

研究背景

機能:

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. Inhibits expression of hypoxia-inducible factor 1alpha and ERK1/2 and p38 MAPK activation. Ligand for alpha1/beta1 integrin.

PTMs:

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 (By similarity).

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 (By similarity).

Proteolytic processing produces the C-terminal NC1 peptide, arresten.

組織特異性:

タンパク質ファミリー:

Alpha chains of type IV collagen have a non-collagenous domain (NC1) at their C-terminus, frequent interruptions of the G-X-Y repeats in the long central triple-helical domain (which may cause flexibility in the triple helix), and a short N-terminal triple-helical 7S domain.

Belongs to the type IV collagen family.
