Summary
Predicted to enable enzyme binding activity and heme binding activity. Predicted to act upstream of or within fatty acid metabolic process. Located in endoplasmic reticulum. Is expressed in early conceptus. Human ortholog(s) of this gene implicated in methemoglobinemia and methemoglobinemia and ambiguous genitalia. Orthologous to human CYB5A (cytochrome b5 type A).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
