CDCP1 in Human Colon Cancer Tissue. CDCP1 was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using Goat Anti-Human CDCP1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2666) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the apices of colonic villi. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

CDCP1, also known as SIMA135, is a novel 140 kDa type I transmembrane glycoprotein with three CUB protein-protein interaction domains in its 635 aa extracellular region. The 148 aa cytoplasmic region contains canonical phosphorylation sites for Sre kinase family members and binding sites for SH3 domains. By alternative splicing, a secreted 310 aa residue form of CDCP1 also exists. The amino-terminal region of approximately 265 aa of the type I membrane CDCP1 can also be proteolytically cleaved. CDCP1 is found on the surface of epithelial and bone marrow-derived stem cells. The extracellular region of human CDCP1 shares 84% aa identity with that of the mouse protein.
