Previous GeneCards Identifiers for CYB5R2 Gene
The protein encoded by this gene belongs to the flavoprotein pyridine nucleotide cytochrome reductase family of proteins. Cytochrome b-type NAD(P)H oxidoreductases are implicated in many processes including cholesterol biosynthesis, fatty acid desaturation and elongation, and respiratory burst in neutrophils and macrophages. Cytochrome b5 reductases have soluble and membrane-bound forms that are the product of alternative splicing. In animal cells, the membrane-bound form binds to the endoplasmic reticulum, where it is a member of a fatty acid desaturation complex. Alternative splicing results in multiple transcript variants.

GeneCards Summary for CYB5R2 Gene
CYB5R2 (Cytochrome B5 Reductase 2) is a Protein Coding gene. Diseases associated with CYB5R2 include Methemoglobinemia. Among its related pathways are Cytochrome P450 - arranged by substrate type and O2/CO2 exchange in erythrocytes. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity and cytochrome-b5 reductase activity, acting on NAD(P)H. An important paralog of this gene is CYB5R3.
UniProtKB/Swiss-Prot Summary for CYB5R2 Gene
NADH-cytochrome b5 reductases are involved in desaturation and elongation of fatty acids, cholesterol biosynthesis, drug metabolism, and, in erythrocyte, methemoglobin reduction (By similarity). Responsible for NADH-dependent lucigenin chemiluminescence in spermatozoa by reducing both lucigenin and 2-[4-iodophenyl]-3-[4-nitrophenyl]-5-[2,4-disulfophenyl]-2H tetrazolium monosodium salt (WST-1).
