Function Probably plays a major role in determining the retinal structure as well as in the closure of the neural tube. .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). {ECO:0000250|UniProtKB:P39060, ECO:0000269|PubMed:11158588, ECO:0000269|PubMed:9008168}.

(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
