Name :
Human PSCA Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, Recombinant
Description :
PSCA (prostate stem cell antigen) is a glycosylphosphatidylinositol (GPI)-anchored cell membrane glycoprotein of the UPAR/Ly6 family. A variety of GPI-linked surface glycoproteins are composed of one or more copies of a conserved domain of ~100 amino-acid residues termed UPAR/Ly6 motif that was originally found in UPAR (Urokinase plasminogen activator surface receptor) and Ly6/CD59. PSCA contains one UPAR/Ly6 domain in the extracellular domain (ECD). Mature human PSCA (amino acids 21-95) shares ~65% amino acid sequence identity with rodent PSCA. PSCA may be involved in the regulation of cell proliferation with a cell-proliferation inhibition activity in vitro. PSCA may be up- or down-regulated in cancer and may promote or suppress the tumor, depending on location. In addition to being highly expressed in the prostate, PSCA is also expressed in the bladder, placenta, colon, kidney, and stomach. PSCA is up-regulated in a large proportion of prostate cancers and is also detected in cancers of the bladder and pancreas. The PSCA 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.

Construct Details :
The recombinant human PSCA-Fc is expressed as a 312-amino acid protein consisting of Leu21 – Ser95 region of PSCA (UniProt accession #O43653) and a C-terminal Fc from human IgG1, which exists as a dimer under non-reducing conditions.
