Summary: Predicted to enable identical protein binding activity; transmembrane ascorbate ferrireductase activity; and transmembrane monodehydroascorbate reductase activity. Predicted to be involved in ascorbate homeostasis; intracellular iron ion homeostasis; and multicellular organismal-level iron ion homeostasis. Predicted to act upstream of or within response to iron ion. Predicted to be located in apical plasma membrane and brush border membrane. Predicted to be active in lysosomal membrane. Orthologous to human CYBRD1 (cytochrome b reductase 1). [provided by Alliance of Genome Resources, Dec 2024]

Data suggest that expression of Cybrd1 in intestinal mucosa can be regulated by dietary factors; here, expression of Cybrd1 in mucosa of duodenum is up-regulated by prebiotic supplement, inulin, in iron-deficiency anemia.
Title: Effects of prebiotic supplementation on the expression of proteins regulating iron absorption in anaemic growing rats.
There is an increase in hippocampal expression of duodenal Cybrd1 following kainic acid-induced excitotoxicity.
Title: Expression and localization of duodenal cytochrome b in the rat hippocampus after kainate-induced excitotoxicity.
Whole-genome profiling reveals that increasing dietary protein from 5 to 40% increases duodenal transcript expression of divalent metal transporter 1 (DMT1) 3.2-fold, duodenal cytochrome b (Dcytb) 1.8-fold, and transferrin receptor (TfR) 1.8-fold.
Title: Increasing dietary protein acutely augments intestinal iron transporter expression and significantly increases iron absorption in rats.
Results suggest that the presence of duodenal cytochrome b (Dcytb) in airway epithelial cells and its regulation by iron may contribute to pulmonary cytoprotection [Dcytb].

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
