Predicted to enable death domain binding activity; protease binding activity; and protein-macromolecule adaptor activity. Acts upstream of or within activation of cysteine-type endopeptidase activity involved in apoptotic process and positive regulation of apoptotic signaling pathway. Located in cytoplasm and nucleus. Is expressed in several structures, including branchial arch; central nervous system; genitourinary system; heart; and sensory organ. Human ortholog(s) of this gene implicated in autosomal recessive non-syndromic intellectual disability. Orthologous to human CRADD (CASP2 and RIPK1 domain containing adaptor with death domain).
