WB Positive detected :293T cells
Function : GTP-binding protein involved in transport from the endoplasmic reticulum to the Golgi apparatus (By similarity). Activated by the guanine nucleotide exchange factor PREB (By similarity). Involved in the selection of the protein cargo and the assembly of the COPII coat complex (By similarity). Synergizes with the cargo receptor SURF4 to mediate the export of lipoproteins from the endoplasmic reticulum, thereby regulating lipoprotein delivery and the maintenance of lipid homeostasis (PubMed:33186557)..
Tissue specificity :Expressed in many tissues including small intestine, liver, muscle and brain..
Subcellular locationi :Endoplasmic reticulum membrane,Peripheral membrane protein. Golgi apparatus, Golgi stack membrane,Peripheral membrane protein.
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 1% w/v BSA, 1X TBST at 4°C overnight.
