Storage ：Antibody store in 10 mM PBS, 0.5mg/ml BSA, 50% glycerol. Shipped at 4°C. Store at-20°C or -80°C. Products are valid for one natural year of receipt.Avoid repeated freeze / thaw cycles.

WB Positive detected ：HeLa cells lyastes

Function ： Binds to OSBPL3, which mediates recruitment of VAPA to plasma membrane sites (PubMed:25447204). The ORP3-VAPA complex stimulates RRAS signaling which in turn attenuates integrin beta-1 (ITGB1) activation at the cell surface (PubMed:25447204). With OSBPL3, may regulate ER morphology (PubMed:16143324). May play a role in vesicle trafficking (PubMed:11511104, PubMed:19289470)..

Tissue specificity ：Ubiquitous.

Subcellular locationi ：Endoplasmic reticulum membrane,Single-pass type IV membrane protein. Cell membrane,Single-pass type IV membrane protein. Cell junction, tight junction. Nucleus membrane.

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