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]. * **UniProt Summary**: Cytochrome b5 is a membrane bound hemoprotein which function as an electron carrier for several membrane bound oxygenases. |Cyt-b5| |L-ascorbic acid metabolic process| |cytochrome-c oxidase activity| |response to cadmium ion| |water-soluble vitamin metabolic process| |vitamin metabolic process| |heme binding| |proton transmembrane transport| |mitochondrial outer membrane| |electron transport chain| |monosaccharide metabolic process| |coenzyme metabolic process| |enzyme binding| |response to metal ion| |monovalent inorganic cation transport| |generation of precursor metabolites and energy| |cofactor metabolic process| |carbohydrate metabolic process| |response to inorganic substance| |inorganic cation transmembrane transport| |cation transmembrane transport| |inorganic ion transmembrane transport| |intracellular membrane-bounded organelle| |cation transport| |carboxylic acid metabolic process| |endoplasmic reticulum membrane| |ion transmembrane transport| |oxidation-reduction process| |oxoacid metabolic process| |organic acid metabolic process| |transmembrane transport| |ion transport| |small molecule metabolic process| |membrane| \\ === CRISPR Data === No hits were found.
