Recently, it was reported that the synthetic　substrate of CDCP1 is cleaved by Membrane-type serine protease 1(MT-SP1), however it is not clear that　this cleavage is involved in anchorage-independence. In this study, we investigated the effect of CDCP1　cleavage by MT-SP1 on anchorage-independence in cancer cells by soft agar assay using MT-SP1 siRNA　and uncleaved CDCP1 mutant (2RKAAres-F). As a result, cleavage of CDCP1 was inhibited in both　experiments, and then the anchorage independence was suppressed. Therefore, it is suggested that the　cleavage of CDCP1 by MT-SP1 is involved in the regulation of anchorage independence in cancer cells.
