Official Full Name
cytochrome b5 reductase 3
Background
This gene encodes cytochrome b5 reductase, which includes a membrane-bound form in somatic cells (anchored in the;endoplasmic reticulum, mitochondrial and other membranes) and a soluble form in erythrocytes. The membrane-bound form;exists mainly on the cytoplasmic side of the endoplasmic reticulum and functions in desaturation and elongation of;fatty acids, in cholesterol biosynthesis, and in drug metabolism. The erythrocyte form is located in a soluble;fraction of circulating erythrocytes and is involved in methemoglobin reduction. The membrane-bound form has both;membrane-binding and catalytic domains, while the soluble form has only the catalytic domain. Alternate splicing;results in multiple transcript variants. Mutations in this gene cause methemoglobinemias.
