Probably plays a major role in determining the retinal structure as well as in the closure of the neural tube.

{ECO:0000250|UniProtKB:P39060}.; [Non-collagenous domain 1]: May regulate extracellular matrix-dependent motility and morphogenesis of endothelial and non-endothelial cells; the function requires homotrimerization and implicates MAPK signaling.

{ECO:0000250|UniProtKB:P39060}.; [Endostatin]: Potently inhibits endothelial cell proliferation and angiogenesis.

May inhibit angiogenesis by binding to the heparan sulfate proteoglycans involved in growth factor signaling (PubMed:9008168).

Inhibits VEGFA isoform VEGF165-induced endothelial cell proliferation and migration.

Seems to inhibit VEGFA-mediated signaling by blocking the interaction of VEGFA to its receptor KDR/VEGFR2 (PubMed:12029087).

Modulates endothelial cell migration in an integrin-dependent manner implicating integrin ITGA5:ITGB1 and to a lesser extent ITGAV:ITGB3 and ITGAV:ITGB5 (PubMed:11158588).

May negatively regulate the activity of homotrimeric non-collagenous domain 1 (By similarity).
