Recombinant Human V-type proton ATPase subunit D (ATP6V1D)

Uniprot Id

Q9Y5K8

Target Species

Human

Target Name

ATP6V1D

Target Full Name

V-type proton ATPase subunit D

Target Function

Subunit of the peripheral V1 complex of vacuolar ATPase. Vacuolar ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells, thus providing most of the energy required for transport processes in the vacuolar system. May play a role in cilium biogenesis through regulation of the transport and the localization of proteins to the cilium.

Target Subcellular Location

Membrane; Peripheral membrane protein; Cytoplasmic side. Note=Localizes to centrosome and the base of the cilium.

Target Protein Families

V-ATPase D subunit family

Target Synonyms

ATP6V1D; ATP6M; VATD; V-type proton ATPase subunit D; V-ATPase subunit D; V-ATPase 28 kDa accessory protein; Vacuolar proton pump subunit D

Target Background

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 and three B subunits, two G subunits plus the C, D, E, F, and H subunits. The V1 domain contains the ATP catalytic site. The V0 domain consists of five different subunits: a, c, c', c", and d. Additional isoforms of many of the V1 and V0 subunit proteins are encoded by multiple genes or alternatively spliced transcript variants. This gene encodes the V1 domain D subunit protein.
