Abstract
Inhibition of synoviolin function was found to activate the cancer-suppressing protein p53. Substances inhibiting the function of synoviolin are useful as cancer therapeutic agents. The inhibition of synoviolin function was also found to lead to the inhibition of p53 ubiquitination, increased activity of p53 phosphorylation proteins, and the like. Based on these findings, the present invention provides methods capable of efficiently screening for cancer therapeutic agents. Further, it was also found that regulation of the autoubiquitination of synoviolin protein suppresses the proliferation of rheumatoid arthritis synovial cells. Substances regulating the autoubiquitination of synoviolin protein are useful as anti-rheumatic agents. Moreover, the present invention provides methods of efficiently screening for anti-rheumatic agents.
