Predicted to enable protein kinase binding activity and protein serine/threonine kinase activator activity. Predicted to be involved in HRI-mediated signaling; extrinsic apoptotic signaling pathway via death domain receptors; and regulation of cysteine-type endopeptidase activity involved in apoptotic process. Predicted to be located in cytosol and mitochondrial inner membrane. Predicted to be active in mitochondrion. Orthologous to human DELE1 (DAP3 binding cell death enhancer 1).
