Intrinsically disordered proteins (IDPs) play important roles in regulation of cell signaling pathways as well as cellular processes. Dysregulation of these proteins is associated with several human diseases. Prostate apoptosis response-4 (Par-4), a proapoptotic tumor suppressor protein, is categorized as an intrinsically disordered protein and downregulation of this protein has been reported in myriad of cancers including glioma, breast cancers, and prostate cancers. The caspase-cleaved fragment of Par-4 (cl-Par-4) plays an active role in tumor suppression by inhibiting several cell survival pathways.

Here, we employed site-directed mutagenesis to introduce a point mutation in the cl-Par-4 wildtype (WT) to generate the …
