V-type proton ATPase subunit d 1 (ATP6V0D1)

The protein contains 351 amino acids for an estimated molecular weight of 40329 Da.

 

Subunit of the integral membrane V0 complex of the lysosomal proton-transporting V-type ATPase (v-ATPase) (PubMed:28296633, PubMed:30374053). V-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 (PubMed:30374053). May play a role in coupling of proton transport and ATP hydrolysis (By similarity). In aerobic conditions, involved in intracellular iron homeostasis, thus triggering the activity of Fe(2+) prolyl hydroxylase (PHD) enzymes, and leading to HIF1A hydroxylation and subsequent proteasomal degradation (PubMed:28296633). May play a role in cilium biogenesis through regulation of the transport and the localization of proteins to the cilium (By similarity). (updated: Oct. 7, 2020)

DESCRIPTION

The vacuolar-type H(+)-ATPase (V-ATPase) is responsible for the acidification of endosomes, lysosomes, and other intracellular organelles. It is also involved in hydrogen ion transport across the plasma membrane into the extracellular space. The V-ATPase is a multisubunit complex with cytosolic and transmembrane domains. The cytosolic catalytic domain consists of 3 A subunits and 3 B subunits, which bind and hydrolyze ATP, as well as regulatory accessory subunits including C (603097), D, and E (108746).

CLONING

Van Hille et al. (1993) cloned subunit D from an osteoclastoma tumor cDNA library with probes developed by PCR from the bovine cDNA sequence. The deduced 274-amino acid protein has a calculated molecular mass of about 32 kD and shows 99% sequence homology with bovine subunit D. Northern blot analysis revealed ubiquitous and comparable expression of a 1.8-kb transcript. While characterizing a genomic clone containing the HSD11B2 gene (614232), Agarwal and White (2000) identified the ATP6V0D1 gene. They obtained the complete ATP6V0D1 sequence from kidney cortical collecting duct cell cDNA and found that the deduced protein is identical to the mouse homolog with the exception of 2 conservative amino acid substitutions. PCR amplification revealed high expression of subunit D in kidney and placenta.

GENE STRUCTURE

Agarwal and White (2000) determined that the ATP6V0D1 gene consists of 8 exons spanning approximately 19 kb. They found that the gene is located immediately adjacent to the HSD11B2 gene and is oriented in the opposite direction, with the 3-prime ends of the 2 genes only 0.5 kb apart. Stimulation of human kidney cortical collecting duct cells or choriocarcinoma cells indicated that their expression is regulated independently.

MAPPING

The International Radiation Hybrid Mapping Consortium mapped the ATP6V0D1 gene to chromosome 16 (TMAP stSG1825). Agarwal and White (2000) identified ATP6V0D1 on a genomic clone mapped to chromosome 16q22.

GENE FUNCTION

Cruciat et al. (2010) found that the prorenin receptor (PRR; 300556) functions in a renin-independent manner as an adaptor between Wnt receptors and the V-ATPase complex. Moreover, PRR and V-ATPase were required to mediate Wnt signaling during anteroposterior patterning of Xenopus early central nervous system development. Cruciat et al. (2010) concluded that their results revealed an unsuspected role for the prorenin receptor, V-ATPase activity, and acidification during Wnt/beta-catenin (116806) signaling.

MOLECULAR GENETICS

Agarwal and White (2000) screened the ATP6V0D1 gene in 17 hypertensive subjects and found no mutations. ... More on the omim web site
