Akr1b1 Gene Summary [Rat]
Enables aldose reductase (NADPH) activity and cis-1,2-dihydro-1,2-dihydroxynaphthalene dehydrogenase activity. Involved in several processes, including cellular response to peptide; inner medullary collecting duct development; and sorbitol biosynthetic process. Located in several cellular components, including Schmidt-Lanterman incisure; Schwann cell microvillus; and mast cell granule. Used to study allergic disease; cataract; diabetic neuropathy; and diabetic retinopathy. Biomarker of diabetic retinopathy; galactosemia; hepatocellular carcinoma; hyperglycemia; and hypokalemia. Human ortholog(s) of this gene implicated in arteriosclerosis; cataract; diabetic neuropathy; diabetic retinopathy; and type 2 diabetes mellitus. Orthologous to human AKR1B1 (aldo-keto reductase family 1 member B). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Akr1b1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
