Prostate apoptosis response-4 (Par-4) is a pro-apoptotic tumor suppressor protein. Down-regulation of this protein has been reported in a myriad of cancers. Conversely, up-regulation of Par-4 is found to be associated with several neurodegenerative disorders. Par-4 is unique in the sense it can selectively induce apoptosis in cancer cells. For this, caspase-dependent intracellular cleavage of Par-4 is essential to produce the functionally active fragment, cl-Par-4 (caspase-cleaved Par-4). The cl-Par-4 protein inhibits the NF-κB-mediated cell survival pathway and causes selective apoptosis in various tumor cells.
Our laboratory is interested in determining the structure of cl-Par-4 and understanding it’s interaction with various …
