in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500 - 1/3000. Predicted molecular weight: 22 kDa.
1/100 - 1/500.
Function 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).
Sequence similarities Belongs to the small GTPase superfamily. SAR1 family.
Cellular localization Endoplasmic reticulum. Golgi apparatus.
