Background
Synonyms:SAR1, SARA, SARA1 Background:Involved in transport from the endoplasmic reticulum to the Golgi apparatus(By similarity). Required to maintain SEC16A localization at discrete locations on the ER membrane perhaps by preventing its dissociation. SAR1A-GTP-dependent assembly of SEC16A on the ER membrane forms an organized scaffold defining endoplasmic reticulum exit sites(ERES).
