About This Section

Entrez Gene summary for COL18A1:

This gene encodes the alpha chain of type XVIII collagen. This collagen is one of the multiplexins, extracellular

matrix proteins that contain multiple triple-helix domains (collagenous domains) interrupted by non-collagenous

domains. The proteolytically produced C-terminal fragment of type XVIII collagen is endostatin, a potent

antiangiogenic protein. Mutations in this gene are associated with Knobloch syndrome. The main features of this

syndrome involve retinal abnormalities, so type XVIII collagen may play an important role in retinal structure and in

neural tube closure. Alternatively spliced transcript variants encoding different isoforms have been found for this

gene. (provided by RefSeq, Sep 2008)

UniProtKB/Swiss-Prot: COIA1_HUMAN, P39060

Function: COLA18A probably plays a major role in determining the retinal structure as well as in the closure of the

neural tube

Function: Endostatin potently inhibits endothelial cell proliferation and angiogenesis. May inhibit angiogenesis by

binding to the heparan sulfate proteoglycans involved in growth factor signaling
