Summaries for ATP6V0A2 Gene

Entrez Gene Summary for ATP6V0A2 Gene

  • The protein encoded by this gene is a subunit of the vacuolar ATPase (v-ATPase), an heteromultimeric enzyme that is present in intracellular vesicles and in the plasma membrane of specialized cells, and which is essential for the acidification of diverse cellular components. V-ATPase is comprised of a membrane peripheral V(1) domain for ATP hydrolysis, and an integral membrane V(0) domain for proton translocation. The subunit encoded by this gene is a component of the V(0) domain. Mutations in this gene are a cause of both cutis laxa type II and wrinkly skin syndrome. [provided by RefSeq, Jul 2009]

GeneCards Summary for ATP6V0A2 Gene

ATP6V0A2 (ATPase, H+ Transporting, Lysosomal V0 Subunit A2) is a Protein Coding gene. Diseases associated with ATP6V0A2 include cutis laxa, autosomal recessive, type iia and wrinkly skin syndrome. 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. An important paralog of this gene is ATP6V0A1.

UniProtKB/Swiss-Prot for ATP6V0A2 Gene

  • Part of the proton channel of V-ATPases. Essential component of the endosomal pH-sensing machinery. May play a role in maintaining the Golgi functions, such as glycosylation maturation, by controlling the Golgi pH.

Tocris Summary for ATP6V0A2 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.

    • The V-ATPase is a heteromultimeric enzyme composed of at least thirteen different subunits. It has a membrane peripheral V1 sector for ATP hydrolysis and an integral V0 for proton translocation. The V1 sector comprises subunits A-H, whereas V0 includes subunits a, d, c, c, and c. Directly interacts with PSCD2 through its N-terminal cytosolic tail in an intra-endosomal acidification-dependent manner. Disruption of this interaction results in the inhibition of endocytosis.

  • Cutis laxa, autosomal recessive, 2A (ARCL2A) [MIM:219200]: A disorder characterized by an excessive congenital skin wrinkling, a large fontanelle with delayed closure, a typical facial appearance with downslanting palpebral fissures, a general connective tissue weakness, and varying degrees of growth and developmental delay and neurological abnormalities. Some affected individuals develop seizures and mental deterioration later in life, whereas the skin phenotype tends to become milder with age. At the molecular level, an abnormal glycosylation of serum proteins is observed in many cases. {ECO:0000269 PubMed:18157129}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Wrinkly skin syndrome (WSS) [MIM:278250]: A rare autosomal recessive disorder characterized by wrinkling of the skin of the dorsum of the hands and feet, an increased number of palmar and plantar creases, wrinkled abdominal skin, multiple musculoskeletal abnormalities, microcephaly, growth failure and developmental delay. {ECO:0000269 PubMed:18157129}.
