Summary: This gene encodes a subunit of a large protein complex known as a vacuolar H+-ATPase (V-ATPase). The protein complex acts as a pump to move protons across the membrane. This movement of protons helps regulate the pH of cells and their surrounding environment. V-ATPase dependent organelle acidification is necessary for such intracellular processes as protein sorting, zymogen activation, and receptor-mediated endocytosis. V-ATPase is comprised of a cytosolic V1 domain and a transmembrane V0 domain. Alternative splicing results in multiple transcript variants. Mutations in this gene are associated with infantile malignant osteopetrosis. [provided by RefSeq, May 2017]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: REVIEWED

Description

Transcript Variant: This variant (1) encodes isoform a, also known as the OC116 protein because it is one of three V-ATPase 116 kD subunits. It is also referred to as the a3 isoform and is induced on osteoclast differentiation. This variant contains a unique 5' end and lacks an internal segment compared to variant 2, which results in an isoform (a) with a different N-terminus than that of isoform b.

Description

Transcript Variant: This variant (2) encodes isoform b, also known as the TCIR7 protein. This protein is expressed in T lymphocytes and is essential for normal T cell activation. This variant uses a transcription start site that is within exon 5 of variant 1, and it also includes the following intron as part of its 5' UTR. The encoded isoform (b) is shorter than isoform a.
