Protein Information (annotations from UniProt)

Database IDHIV0007020
UniProt IDO94979
Primary gene name(s)SEC31A
Synonym gene name(s)KIAA0905, SEC31L1
Protein nameProtein transport protein Sec31A
Protein functionComponent of the coat protein complex II, COPII which promotes the formation of transport vesicles from the endoplasmic reticulum, ER. The coat has two main functions, the physical deformation of the endoplasmic reticulum membrane into vesicles and the selection of cargo molecules, By similarity. {ECO:0000250, ECO:0000269|PubMed:10788476}.
Subcellular locationCytoplasm {ECO:0000250}. Cytoplasmic vesicle, COPII-coated vesicle membrane;
Peripheral membrane protein;
Cytoplasmic side. Endoplasmic reticulum membrane {ECO:0000250};
Peripheral membrane protein {ECO:0000250}. Note=Associates with membranes in a GTP-dependent manner. {ECO:0000250}.
