VHAA2_ARATH - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: VHAA2_ARATH
• UniProt AC: Q9SJT7
• Protein Name: V-type proton ATPase subunit a2
• Gene Name: VHA-a2
• Organism: Arabidopsis thaliana (Mouse-ear cress).
• Sequence Length: 821
• Subcellular Localization: Vacuole membrane ; Multi-pass membrane protein .
• Protein Description: 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)..
