Protein: Protein transport protein SEC23 (P15303)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Component 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. SEC23 interacts with BET3 in order to target TRAPPI complex to COPII involved in internalization of plasma membrane proteins like the maltose transporter.
Subcellular location: Cytoplasmic vesicle, COPII-coated vesicle membrane {ECO:0000269|PubMed:10720463, ECO:0000269|PubMed:11086000, ECO:0000269|PubMed:12235121, ECO:0000269|PubMed:8548805, ECO:0000269|PubMed:9568718}; Peripheral membrane protein {ECO:0000269|PubMed:11086000, ECO:0000269|PubMed:8548805}; Cytoplasmic side {ECO:0000269|PubMed:8548805}.
