Recombinant Human Prostate stem cell antigen (PSCA)

Uniprot Id

O43653

Target Species

Human

Target Name

PSCA

Target Full Name

Prostate stem cell antigen

Target Function

May be involved in the regulation of cell proliferation. Has a cell-proliferation inhibition activity in vitro.; May act as a modulator of nicotinic acetylcholine receptors (nAChRs) activity. In vitro inhibits nicotine-induced signaling probably implicating alpha-3:beta-2- or alpha-7-containing nAChRs.

Target Subcellular Location

Cell membrane; Lipid-anchor, GPI-anchor.

Target Tissue Specificity

Highly expressed in prostate (basal, secretory and neuroendocrine epithelium cells). Also found in bladder (transitional epithelium), placenta (trophoblasts), stomach (neuroendocrine cells), colon (neuroendocrine cells) and kidney (collecting ducts). Over

Target Research Area

Target Synonyms

PSCA; UNQ206/PRO232; Prostate stem cell antigen

Target Background

This gene encodes a glycosylphosphatidylinositol-anchored cell membrane glycoprotein. In addition to being highly expressed in the prostate it is also expressed in the bladder, placenta, colon, kidney, and stomach. This gene is up-regulated in a large proportion of prostate cancers and is also detected in cancers of the bladder and pancreas. This gene includes a polymorphism that results in an upstream start codon in some individuals; this polymorphism is thought to be associated with a risk for certain gastric and bladder cancers. Alternative splicing results in multiple transcript variants.
