Novel Death Defying Domain in met entraps the active site of caspase‐3 and blocks apoptosis in hepatocytes
Jihong Ma, Chunbin Zou, Lida Guo, Danushka S. Seneviratne, Xinping Tan, Yong‐Kook Kwon, Jiyan An, Robert Bowser, Marie C. DeFrances, Reza Zarnegar – 3 October 2013 – Met, the transmembrane tyrosine kinase receptor for hepatocyte growth factor (HGF), is known to function as a potent antiapoptotic mediator in normal and neoplastic cells. Herein we report that the intracellular cytoplasmic tail of Met has evolved to harbor a tandem pair of caspase‐3 cleavage sites, which bait, trap, and disable the active site of caspase‐3, thereby blocking the execution of apoptosis.
