Predicted to enable heme binding activity and holocytochrome-c synthase activity. Predicted to be involved in cytochrome c-heme linkage. Predicted to be located in membrane. Predicted to be active in cytosol and mitochondrion. 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). [provided by Alliance of Genome Resources, Apr 2022]
