Rabbit anti-Human ATP6AP1 Polyclonal Antibody

Uniprot Id

Q15904

Target Species

Human

Target Name

ATP6AP1

Target Full Name

V-type proton ATPase subunit S1

Target Function

Accessory subunit of the proton-transporting vacuolar (V)-ATPase protein pump, which is required for luminal acidification of secretory vesicles. Guides the V-type ATPase into specialized subcellular compartments, such as neuroendocrine regulated secretory vesicles or the ruffled border of the osteoclast, thereby regulating its activity. Involved in membrane trafficking and Ca(2+)-dependent membrane fusion. May play a role in the assembly of the V-type ATPase complex. 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.

Target Involvement

Immunodeficiency 47 (IMD47)

Target Subcellular Location

Endoplasmic reticulum membrane; Single-pass membrane protein. Endoplasmic reticulum-Golgi intermediate compartment membrane.

Target Protein Families

Vacuolar ATPase subunit S1 family

Target Tissue Specificity

widely expressed, with highest levels in brain and lowest in liver and duodenum.

Target Synonyms

ATP6AP1; ATP6IP1; ATP6S1; VATPS1; XAP3; V-type proton ATPase subunit S1; V-ATPase subunit S1; Protein XAP-3; V-ATPase Ac45 subunit; V-ATPase S1 accessory protein; Vacuolar proton pump subunit S1

Target Background

This gene encodes a component of a multisubunit enzyme that mediates acidification of eukaryotic intracellular organelles. Vacuolar ATPase (V-ATPase) is comprised of a cytosolic V1 (site of the ATP catalytic site) and a transmembrane V0 domain. V-ATPase dependent organelle acidification is necessary for such intracellular processes as protein sorting, zymogen activation, and receptor-mediated endocytosis. The encoded protein of this gene may assist in the V-ATPase-mediated acidification of neuroendocrine secretory granules. This protein may also play a role in early development.
