Protein

GTP-binding protein SAR1a

Gene
SAR1A, SAR1, SARA, SARA1
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

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).1 Publication
