CYB5RL (Cytochrome B5 Reductase Like) is a Protein Coding gene. Among its related pathways are Metabolism and Amino sugar and nucleotide sugar metabolism. GO annotations related to CYB5RL include oxidoreductase activity and cytochrome-b5 reductase activity, acting on NAD(P)H. An important paralog of CYB5RL is ENSG00000256407. NADH-cytochrome b5 reductases are involved in desaturation and elongation of fatty acids, cholesterol biosynthesis, drug metabolism, and, in erythrocyte, methemoglobin reduction.
