CUB domain-containing protein 1 (CDCP1) is a protein that in humans is encoded by the CDCP1 gene.[5][6] CDCP1 has also been designated as CD318 (cluster of differentiation 318) and Trask (Transmembrane and associated with src kinases). Alternatively spliced transcript variants encoding distinct isoforms have been reported.[6]

Function

edit

CDCP1 is a 140 kD transmembrane glycoprotein with a large extracellular domain (ECD) containing two CUB domains, and a smaller intracellular domain (ICD). CDCP1 is cleaved by serine proteases at the extracellular domain next to Arg368 to generate a truncated molecule of 80 kDa size.[7] Different cell lines express different amounts of p140 and p80, depending on the activity of endogenous serine proteases.

The intracellular domain of CDCP1 contains five tyrosine residues - Y707, Y734, Y743, Y762 and Y806. The tyrosine phosphorylation of CDCP1 in cultured cells occurs when cells are induced to detach by trypsin or EDTA, or seen spontaneously during mitotic detachment.

Clinical significance

edit

The phosphorylation of CDCP1 is seen in many cancers, including some pre-invasive cancers as well as in invasive tumors and in tumor metastases.[8]
