Gene: Cyb5b (cytochrome b5 type B) Mus musculus
Symbol: Cyb5b
Name: cytochrome b5 type B
Description: Predicted to have electron transfer activity; enzyme activator activity; and heme binding activity. Predicted to be involved in oxidation-reduction process. Localizes to mitochondrial inner membrane. Is expressed in several structures, including adrenal gland; craniocervical region bone; gut; neural retina; and urinary system. Orthologous to human CYB5B (cytochrome b5 type B); INTERACTS WITH 1,2-dimethylhydrazine; 17beta-estradiol; 2,3,7,8-tetrachlorodibenzodioxine.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: 1810044O22Rik; AU015618; Cyb5m; cytochrome b5 outer mitochondrial membrane isoform
