Predicted to enable heme binding activity and holocytochrome-c synthase activity. Predicted to be involved in cytochrome c-heme linkage. Located in mitochondrion. Is active in cytosol. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and liver and biliary system. Used to study microphthalmia. Human ortholog(s) of this gene implicated in linear skin defects with multiple congenital anomalies 1 and microphthalmia. Orthologous to human HCCS (holocytochrome c synthase).
