MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] NCB5OR is a flavohemoprotein that contains functional domains found in both cytochrome b5 (CYB5A; MIM 613218) and CYB5 reductase (CYB5R3; MIM 613213) (Zhu et al., 1999 [PubMed 10611283]).[supplied by OMIM, Jan 2010]
PHENOTYPE: Homozygous null mice exhibit defects in glucose homeostasis and pancreatic abnormalities consistent with symptoms of diabetes. [provided by MGI curators]
