Subcellular location [CC][Isoform 1]: Cytoplasm {ECO:0000250}. Cytoplasm, cytoskeleton {ECO:0000250}. Membrane {ECO:0000250}.;
[Isoform 2]: Cytoplasm {ECO:0000250}. Mitochondrion {ECO:0000250}. Mitochondrion outer membrane {ECO:0000250}. Note=Under basal conditions, localizes to both cytosolic and mitochondrial compartments. Relocalizes from the cytosolic to the mitochondrial compartment during apoptosis. Its targeting to the outer mitochondrial membrane (OMM) involves an association with import receptors of the TOM complex and is required to promote proapoptotic activity (By similarity). {ECO:0000250}.
