About ATP6V1B2

Cytogenetic location: 8p21.3 Genomic coordinates (GRCh38): 8:20,197,381-20,221,696 (from NCBI)

This gene has 6 transcripts (splice variants), 280 orthologues, 4 paralogues and is associated with 6 phenotypes. Ubiquitous expression in brain (RPKM 48.6), kidney (RPKM 28.3) and 24 other tissues.

Summary

This gene encodes a component of vacuolar ATPase (V-ATPase), a multisubunit Enzyme that mediates acidification of eukaryotic intracellular organelles. V-ATPase dependent organelle acidification is necessary for such intracellular processes as protein sorting, zymogen activation, receptor-mediated endocytosis, and synaptic vesicle proton gradient generation. V-ATPase is composed of a cytosolic V1 domain and a transmembrane V0 domain. The V1 domain consists of three A, three B, and two G subunits, as well as a C, D, E, F, and H subunit. The V1 domain contains the ATP catalytic site. The protein encoded by this gene is one of two V1 domain B subunit isoforms and is the only B isoform highly expressed in osteoclasts.
