NB5R4 Polyclonal Antibody

catalytic activity:NADH + 2 ferricytochrome b5 = NAD(+) + H(+) + 2 ferrocytochrome b5.,cofactor:FAD.,function:NADH-cytochrome b5 reductase involved in endolasmic 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). Reduces a variety of substrates in vitro, such as cytochrome c, feericyanide and methemoglobin.,polymorphism:Variants Arg-187 and Arg-223 do not influence the pathogenesis of non-autoimmune diabetes.,similarity:Belongs to the flavoprotein pyridine nucleotide cytochrome reductase family.,similarity:Contains 1 CS domain.,similarity:Contains 1 cytochrome b5 heme-binding domain.,similarity:Contains 1 FAD-binding FR-type domain.,subcellular location:Soluble protein.,tissue specificity:Widely expressed.,
