Predicted to enable tumor necrosis factor receptor superfamily binding activity; virus receptor activity; and zinc ion binding activity. Predicted to be involved in several processes, including activation-induced cell death of T cells; apoptotic signaling pathway; and positive regulation of mitochondrial outer membrane permeabilization involved in apoptotic signaling pathway. Predicted to be located in mitochondrion and nucleoplasm. Orthologous to human SIVA1 (SIVA1 apoptosis inducing factor). [provided by Alliance of Genome Resources, Apr 2022]
