WB Positive detected ：HepG2 cells 

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.., [Endostatin]: Potently inhibits endothelial cell proliferation and angiogenesis (PubMed:9459295). May inhibit angiogenesis by binding to the heparan sulfate proteoglycans involved in growth factor signaling (By similarity). Inhibits VEGFA-induced endothelial cell proliferation and migration. Seems to inhibit VEGFA-mediated signaling by blocking the interaction of VEGFA to its receptor KDR/VEGFR2. Modulates endothelial cell migration in an integrin-dependent manner implicating integrin ITGA5:ITGB1 and to a lesser extent ITGAV:ITGB3 and ITGAV:ITGB5 (By similarity). May negatively regulate the activity of homotrimeric non-collagenous domain 1 (PubMed:11257123)..

Tissue specificity ：Present in multiple organs with highest levels in liver, lung and kidney.

Subcellular locationi ：Secreted, extracellular space, extracellular matrix. Secreted, extracellular space, extracellular matrix, basement membrane.,[Non-collagenous domain 1]: Secreted, extracellular space, extracellular matrix, basement membrane. Secreted.,[Endostatin]: Secreted. Secreted, extracellular space, extracellular matrix, basement membrane.

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 1% w/v BSA, 1X TBST at 4°C overnight.
