Summaries for ATP6V1B2 Gene

Entrez Gene Summary for ATP6V1B2 Gene

  • 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.

GeneCards Summary for ATP6V1B2 Gene

ATP6V1B2 (ATPase, H+ Transporting, Lysosomal 56/58kDa, V1 Subunit B2) is a Protein Coding gene. Diseases associated with ATP6V1B2 include autosomal dominant deafness-onychodystrophy syndrome and pigmented villonodular synovitis. Among its related pathways are Signaling by GPCR and Insulin receptor signalling cascade. GO annotations related to this gene include hydrogen ion transmembrane transporter activity and proton-transporting ATPase activity, rotational mechanism. An important paralog of this gene is ATP6V1B1.

  • Non-catalytic subunit of the peripheral V1 complex of vacuolar ATPase. V-ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells

Tocris Summary for ATP6V1B2 Gene

  • H+-ATPase (also known as vacuolar ATPase, V-ATPase) is a enzyme transporter that functions to acidify intracellular compartments in eukaryotic cells. It is ubiquitously expressed and is present in endomembrane organelles such as vacuoles, lysosomes, endosomes, the Golgi apparatus, chromaffin granules and coated vesicles, as well as in the plasma membrane. H+-ATPase is a multisubunit complex composed of two domains. The V1 domain is responsible for ATP hydrolysis and the V0 domain is responsible for protein translocation. There are two main mechanisms of regulating H+-ATPase activity; recycling of H+-ATPase-containing vesicles to and from the plasma membrane and glucose-sensitive assembly/disassembly of the holoenzyme complex. These transporters play an important role in processes such as receptor-mediated endocytosis, protein degradation and coupled transport. They have a function in bone reabsorption and mutations in the A3 gene cause recessive osteopetrosis. Furthermore, H+-ATPases have been implicated in tumor metastasis and regulation of sperm motility and maturation.
