Protein attributes

Sequence length	840 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Part of the proton channel of the V-ATPase that is involved in normal vectorial acid transport into the urine by the kidney By similarity.
Subunit structure	The V-ATPase is a heteromultimeric enzyme composed of at least thirteen different subunits. It has a membrane peripheral V1 sector for ATP hydrolysis and an integral V0 for proton translocation. The V1 sector comprises subunits A-H, whereas V0 includes subunits a, d, c, c', and c''.
Subcellular location	Apical cell membrane; Multi-pass membrane protein. Note: Present at high density almost exclusively on the apical surface of alpha-intercalated cells in the cortical collecting ducts of the distal nephron.
Tissue specificity	Expressed in adult and fetal kidney. Found in the inner ear. Ref.7
Involvement in disease	Renal tubular acidosis, distal, autosomal recessive (RTADR) [MIM:602722]: An autosomal recessive disease characterized by reduced ability to acidify urine, variable hyperchloremic hypokalemic metabolic acidosis, nephrocalcinosis, and nephrolithiasis. It is due to functional failure of alpha-intercalated cells of the cortical collecting duct of the distal nephron, where vectorial proton transport is required for urinary acidification. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.1 Ref.7
Sequence similarities	Belongs to the V-ATPase 116 kDa subunit family.
