a protein kinase of the STE20 family. Activated by apoptotic signals as well as other stress conditions. Full activation requires both phosphorylation and caspase-mediated cleavage. Following cleavage by caspase-3, undergoes irreversible autophosphorylation. Full-length is mainly unphosphorylated in the rat thymus and cultured cells, whereas caspase-3-cleaved MST2 in apoptotic cells is highly phosphorylated.
