General annotation (Comments)

Function

Functions with VOA1 in assembly of the integral membrane sector (also called V0 sector) of the V-ATPase in the endoplasmic reticulum. Escorts the assembled V0 sector in COPII vesicles. Also required for normal packaging of the SNARE BOS1 and possibly the ER to Golgi transport receptor ERV29. Ref.1 Ref.5 Ref.7 Ref.9 Ref.10 Ref.12

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein. Endoplasmic reticulum-Golgi intermediate compartment membrane; Multi-pass membrane protein By similarity. Cytoplasmic vesicle › COPII-coated vesicle membrane; Multi-pass membrane protein Ref.1 Ref.12.

Miscellaneous

Present with 1480 molecules/cell in log phase SD medium.

Sequence similarities

Belongs to the VMA21 family.
