General annotation (Comments)
| Function | Required for assembly and activity of the vacuolar ATPase. Potential role in differential targeting and regulation of the enzyme for a specific organelle 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 | Cytoplasmic vesicle membrane; Multi-pass membrane protein. Melanosome. Note: Coated vesicle. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Ref.7 Ref.8 |
| Sequence similarities | Belongs to the V-ATPase 116 kDa subunit family. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q93050-2) Also known as: I; This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q93050-1) Also known as: II; The sequence of this isoform differs from the canonical sequence as follows: 705-710: Missing. | ||||||
| Isoform 3 (identifier: Q93050-3) The sequence of this isoform differs from the canonical sequence as follows: 141-141: E → EAELHHQQ 705-710: Missing. | ||||||
| Note: No experimental confirmation available. |
