Supplementary information

Cbr1 also known as carbonyl reductase 1 is an important enzyme in the reduction of carbonyl compounds to their alcohol forms. It weighs around 30 kDa and exhibits a wide expression across various tissues but is notably present in the liver and heart. The enzyme acts as a monomer and follows an NADPH-dependent mechanism for its action playing an important role in the detoxification of xenobiotics and the metabolism of endogenous compounds.
Biological function summary

Carbonyl reductase 1 functions in the metabolism of prostaglandins steroids and aromatic aldehydes. Cbr1 is not known to form part of a larger protein complex but acts independently to execute its enzymatic roles. It exhibits broad substrate specificity allowing it to reduce a variety of carbonyl groups which influences several physiological processes such as lipid metabolism and hormone synthesis.

Pathways

The enzyme plays an important role in the prostaglandin metabolic pathway where it reduces prostaglandin E2. Additionally Cbr1 interacts within the retinol metabolism pathway. In these pathways it functions alongside proteins such as aldo-keto reductases and aldose reductase sharing substrate specificity which impacts cellular responses and metabolic regulation.

Cbr1 influences the development of drug resistance in cancer therapy particularly in anthracycline-treated cancers due to its role in drug metabolism. It also associates with cardiovascular conditions where its metabolic activity might affect oxidative stress levels. Connections with other proteins such as superoxide dismutases link Cbr1 to oxidative stress response pathways impacting disease progression and therapy outcomes.

Target data

NADPH-dependent reductase with broad substrate specificity. Catalyzes the reduction of a wide variety of carbonyl compounds including quinones, prostaglandins, menadione, plus various xenobiotics. Catalyzes the reduction of the antitumor anthracyclines doxorubicin and daunorubicin to the cardiotoxic compounds doxorubicinol and daunorubicinol (PubMed : 15799708, PubMed : 17344335, PubMed : 17912391, PubMed : 18449627, PubMed : 18826943, PubMed : 1921984, PubMed : 7005231). Can convert prostaglandin E to prostaglandin F2-alpha (By similarity). Can bind glutathione, which explains its higher affinity for glutathione-conjugated substrates. Catalyzes the reduction of S-nitrosoglutathione (PubMed : 17344335, PubMed : 18826943). In addition, participates in the glucocorticoid metabolism by catalyzing the NADPH-dependent cortisol/corticosterone into 20beta-dihydrocortisol (20b-DHF) or 20beta-corticosterone (20b-DHB), which are weak agonists of NR3C1 and NR3C2 in adipose tissue (PubMed : 28878267).
