    Summary
    Enables electron transfer activity. Involved in sterol biosynthetic process. Located in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in methemoglobinemia and methemoglobinemia and ambiguous genitalia. Orthologous to human CYB5A (cytochrome b5 type A) and CYB5B (cytochrome b5 type B).
