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 act upstream of or within apoptotic process. Located in mitochondrion. Orthologous to human DELE1 (DAP3 binding cell death enhancer 1).
