This entry represents the transmembrane domain from ER/Golgi membrane proteins including V0 complex accessory subunit Ac45 (ATP6AP1, also known as V-type proton ATPase subunit S1) from animals and the yeast homologue V0 assembly protein 1 (VOA1) which are essential for V0 ATPase assembly, stability and function [1,2]. In humans, mutations of ATP6AP1 cause immunodeficiency with hypogammaglobulinemia, hepatopathy and neurocognitive abnormalities [3]. This entry also includes ER membrane BIG1 proteins from yeast, involved in cell wall biogenesis.
