| Research Abstract |
In this study, we found the three functions of CDCP1 in cancer cells. First, CUB2 and CUB3 in the extracellular domain of CDCP1 and the region including Tyrosine734 in the intracellular domain of CDCP1 might contribute to regulate anchorage-independent growth in cancer cell. Second, CDCP1 regulates cancer invasion through regulation of MMP-9 secretion and membranous transportation of MT1-MMP to invadopodia. Finally, induction of CDCP1 expression by Ras along with tyrosine phosphorylation of CDCP1 by Src family kinases is required for Ras-mediated oncogenic phenotypes, such as anchorage-independent growth, invasion and metastasis.
