Summary
Enables proton-transporting ATPase activity, rotational mechanism. Involved in vacuolar acidification. Located in fungal-type vacuole membrane. Part of vacuolar proton-transporting V-type ATPase, V1 domain. Human ortholog(s) of this gene implicated in autosomal recessive cutis laxa type IID and developmental and epileptic encephalopathy 93. Orthologous to human ATP6V1A (ATPase H+ transporting V1 subunit A). [provided by Alliance of Genome Resources, Jul 2025]
