TNS4, as the others tensins, contains a phosphotyrosine-binding domain (PTB), which plays the role of interacting with the cytoplasmic tail of the β-integrin. Also TNS4 is found to play a central role in HGF-induced tubulogenesis. The role of TNS4 on cell proliferation is found to be minimal and not up to the level of the effect of migration. By enhancing the motility and having the effect on the tubulogenesis, TNS4 is believed to have a role in cancer cell metastasis. The role of cten in cancer is not well defined. In prostate cancer it is down-regulated, where in normal cells it is localized to focal adhesions recruiting the tumour suppressor, deleted in liver cancer (DLC-1), thus suppressing tumorigenesis. Cten in prostate epithelial cells has also been found to regulate staurosporine-induced apoptosis where cten is cleaved by caspase 3 and results in reduction in cell growth rate. Therefore, loss of cten expression may lead to uncontrolled cell growth and result in cell transformation. Accordingly, in prostate cancer, cten may function as a tumour suppressor protein.
