Prostate stem cell antigen is a protein that in humans is encoded by the PSCA gene.[5][6]

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 has a nonsynonymous nucleotide polymorphism at its start codon.[6]

Clinical significance[edit]

This gene is up-regulated in a large proportion of prostate cancers and is also detected in cancers of the bladder and pancreas.[6]
