NCIt definition : Prostate stem cell antigen (123 aa, 13 kDa) is encoded by the human PSCA gene. This
protein may play a role in the regulation of cell proliferation.;
NCIt note : Prostate stem cell antigen is a glycosylphosphatidylinositol (GPI)-linked cell surface
antigen whose expression in prostate cancer is directly correlated with disease severity,
and inversely correlated with prognosis. This protein has been utilized as a biomarker
for bladder, prostate, and pancreatic cancers.;
