Enables CD27 receptor binding activity; tumor necrosis factor receptor binding activity; and virus receptor activity. Predicted to be involved in several processes, including activation-induced cell death of T cells; negative regulation of NF-kappaB transcription factor activity; and positive regulation of mitochondrial outer membrane permeabilization involved in apoptotic signaling pathway. Predicted to act upstream of or within apoptotic process. Predicted to be located in mitochondrion and nucleoplasm. Is expressed in cerebral cortex ventricular layer. Orthologous to human SIVA1 (SIVA1 apoptosis inducing factor). [provided by Alliance of Genome Resources, Apr 2022]
