This gene encodes a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins. This member catalyzes the reduction of a number of aldehydes, including the aldehyde form of glucose, and is thereby implicated in the development of diabetic complications by catalyzing the reduction of glucose to sorbitol. Multiple pseudogenes have been identified for this gene. The nomenclature system used by the HUGO Gene Nomenclature Committee to define human aldo-keto reductase family members is known to differ from that used by the Mouse Genome Informatics database.

GeneCards Summary for AKR1B1 Gene
AKR1B1 (Aldo-Keto Reductase Family 1 Member B) is a Protein Coding gene. Diseases associated with AKR1B1 include Diabetic Cataract and Diabetic Autonomic Neuropathy. Among its related pathways are acetone degradation I (to methylglyoxal) and Glycerolipid metabolism. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity and aldo-keto reductase (NADP) activity. An important paralog of this gene is AKR1B10.
UniProtKB/Swiss-Prot Summary for AKR1B1 Gene
Catalyzes the NADPH-dependent reduction of a wide variety of carbonyl-containing compounds to their corresponding alcohols. Displays enzymatic activity towards endogenous metabolites such as aromatic and aliphatic aldehydes, ketones, monosacharides, bile acids and xenobiotics substrates. Key enzyme in the polyol pathway, catalyzes reduction of glucose to sorbitol during hyperglycemia (PubMed:1936586). Reduces steroids and their derivatives and prostaglandins. Displays low enzymatic activity toward all-trans-retinal, 9-cis-retinal, and 13-cis-retinal (PubMed:12732097, PubMed:19010934, PubMed:8343525). Catalyzes the reduction of diverse phospholipid aldehydes such as 1-palmitoyl-2-(5-oxovaleroyl)-sn -glycero-3-phosphoethanolamin (POVPC) and related phospholipid aldehydes that are generated from the oxydation of phosphotidylcholine and phosphatdyleethanolamides (PubMed:17381426). Plays a role in detoxifying dietary and lipid-derived unsaturated carbonyls, such as crotonaldehyde, 4-hydroxynonenal, trans-2-hexenal, trans-2,4-hexadienal and their glutathione-conjugates carbonyls (GS-carbonyls) (PubMed:21329684).
Aldose reductase (also known as aldehyde reductase) catalyzes the reduction of a wide variety of hydrophobic and hydrophilic carbonyl-containing compounds to their corresponding alcohols. This enzyme is cytosolic, exists as a monomer and requires NADPH as a co-factor.
