CYB5A - cytochrome b5 type A Gene

Homo sapiens

Also known as CYB5; MCB5; METAG

Gene ID: 1528 | Gene type: protein coding

About CYB5A

Cytogenetic location: 18q22.3 Genomic coordinates (GRCh38): 18:74,250,846-74,291,963 (from NCBI)

This gene has 7 transcripts (splice variants), 214 orthologues, 1 paralogue and is associated with 3 phenotypes. Broad expression in liver (RPKM 226.1), kidney (RPKM 141.0) and 16 other tissues.

Summary

The protein encoded by this gene is a membrane-bound cytochrome that reduces ferric hemoglobin (methemoglobin) to ferrous hemoglobin, which is required for stearyl-CoA-desaturase activity. Defects in this gene are a cause of type IV hereditary methemoglobinemia. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2010]
