VHAA2_ARATH | function | Essential component of the vacuolar proton pump (V-ATPase), a multimeric enzyme that catalyzes the translocation of protons across the membranes. Required for assembly and activity of the V-ATPase. Involved in vacuolar nutrient storage (e.g. accumulation and storage of nitrate) and in tolerance to some toxic ions (e.g. zinc ions sequestration in vacuoles). |
VHAA2_ARATH | similarity | Belongs to the V-ATPase 116 kDa subunit family. |
VHAA2_ARATH | tissue specificity | Expressed in etiolated seedlings hypocotyls. |
