Anti-CBR1 Picoband® Antibody Fluoro488 Conjugated

Carbonyl reductase 1, also known as CBR1, is an enzyme which in humans is encoded by the CBR1 gene. It is mapped to 21q22.12. The protein encoded by this gene belongs to the short-chain dehydrogenases/reductases (SDR) family, which function as NADPH-dependent oxidoreductases having wide specificity for carbonyl compounds, such as quinones, prostaglandins, and various xenobiotics. Alternatively spliced transcript variants have been found for this gene.

Carbonyl reductase [NADPH] 1; 15-hydroxyprostaglandin dehydrogenase [NADP (+) ]; NADPH-dependent carbonyl reductase 1; Prostaglandin 9-ketoreductase; Prostaglandin-E (2) 9-reductase; Short chain dehydrogenase/reductase family 21C member 1; CBR1; CBR; CRN; SDR21C1

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. Can convert prostaglandin E2 to prostaglandin F2-alpha. Can bind glutathione, which explains its higher affinity for glutathione-conjugated substrates. Catalyzes the reduction of S-nitrosoglutathione.
