- Role of JSAP in cell division control and cancer, The 75th Annual Meeting of the Japanese Cancer Association, 2016/10/06, Without Invitation, Japanese, Proper cell cycle regulation is essential for normal cell function, and its dysregulation is often associated with cellular transformation and tumorigenesis. We previously showed that the JSAP group of proteins, JSAP1 and JSAP2, plays a role in cytokinesis, the final stage of cell division. In addition, recent studies have reported that overexpression of JSAP2 is correlated with poor prognosis in hepatocellular carcinoma and non-small cell lung cancer. To date, however, functional role of JSAP in cell division control and cancer remains largely unknown. In this study, we investigated the effect of high expression of JSAP on cultured cells. Overexpression of wild-type JSAP1 or JSAP2 (JSAP1_WT or JSAP2_WT), but not mutant JSAP1 or JSAP2 lacking kinesin-1 heavy chain-binding domain (KBD) (JSAP1_ΔKBD or JSAP2_ΔKBD), caused nuclear morphological abnormalities. Furthermore, prolonged M phase and cell death were observed in HeLa cells overexpressing JSAP_WT, but not JSAP_ΔKBD. Together, these findings may suggest that JSAP plays a critical role in the regulation of mitosis, particularly chromosome segregation through interaction with kinesin-1.
