Protein Construction: A DNA sequence encoding the mouse CDCP1 (Q5U462) (Met1-Leu666) was expressed, fused with the Fc region of human IgG1 at the C-terminus.
Stability and Storage: Lyophilized proteins are stable for up to 12 months when stored at -20 to -80?C. Reconstituted protein solution can be stored at 4-8? for 2-7 days. Aliquots of reconstituted samples are stable at < -20? for 3 months.
FormulationLyophilized from sterile PBS, pH 7.4
Background:CDCP1 contains three extracellular CUB domains. It is a putative stem cell marker that is highly expressed in some human cancer cells and in both, typical and atypical (cancerous) colons. It interacts with CDH2/N-cadherin, CDH3/P-cadherin, SDC1/syndecan-1, SDC4/syndecan-4 and the serine protease ST14/MT-SP1. It also interacts with SRC and PRKCG/protein kinase C gamma. CDCP1 is taken as a key regulator of EGF/EGFR-induced cell migration. It has been shown that signaling via EGF/EGFR induces migration of ovarian cancer Caov3 and OVCA420 cells with concomitant up-regulation of CDCP1 mRNA and protein. Consistent with a role in cell migration CDCP1 relocates from cell-cell junctions to punctate structures on filopodia after activation of EGFR. It may be involved in cell adhesion and cell matrix association. It also may play a role in the regulation of anchorage versus migration or proliferation versus differentiation via its phosphorylation. It has been taken as a novel marker for leukemia diagnosis and for immature hematopoietic stem cell subsets.
