Protein transport protein Sec31A is a protein that in humans is encoded by the SEC31A gene.The protein encoded by this gene is similar to yeast Sec31 protein. Yeast Sec31 protein is known to be a component of the COPII protein complex which is responsible for vesicle budding from endoplasmic reticulum (ER). This protein was found to colocalize with SEC13 one of the other components of COPII in the subcellular structures corresponding to the vesicle transport function.
