Cytochrome b5 reductase 4

Gene

Cyb5r4

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

NADH-cytochrome b5 reductase involved in endoplasmic reticulum stress response pathway. Plays a critical role in protecting pancreatic beta-cells against oxidant stress, possibly by protecting the cell from excess buildup of reactive oxygen species (ROS).1 Publication

Catalytic activityi

NADH + 2 ferricytochrome b5 = NAD+ + H+ + 2 ferrocytochrome b5.

Pathology & Biotechi

Disruption phenotypei

Mice display insulin-deficient diabetes. Embryos and fetus develop normally. At 4 weeks of age, mice show have normal blood glucose levels but impaired glucose tolerance. Isolated islets have markedly impaired glucose- or arginine-stimulated insulin secretion. By 7 weeks of age, they develop severe hyperglycemia with markedly decreased serum insulin levels and nearly normal insulin tolerance. As the animals age, there is a progressive loss of beta cells in pancreatic islets, but there is no loss of alpha, delta, or PP cells. 4 week-old mice have enhanced sensitivity to the diabetogenic agent streptozotocin.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
