SEC16A Proteins and Enzymes

SEC16A is required for secretory cargo traffic from the endoplasmic reticulum to the Golgi apparatus. It defines endoplasmic reticulum exit sites (ERES). SAR1A-GTP-dependent assembly of SEC16A on the ER membrane forms an organized scaffold defining an ERES. It is required for normal transitional endoplasmic reticulum (tER) organization.
