Peptide Antagonists Of Cell Proliferation Protein Kinase

Protein kinase R is a critical enzyme in the interferon signalling pathway which has been implicated in cross-talk between this pathway and the tumor necrosis factor-a apoptosis signalling pathway. Thus, peptide antagonists of this kinase may inhibit apoptosis or stimulate cell proliferation under conditions of cell cycle arrest.
