Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Converts testosterone (T) into 5-alpha-dihydrotestosterone (DHT) and progesterone or corticosterone into their corresponding 5-alpha-3-oxosteroids. It plays a central role in sexual differentiation and androgen physiology.CATALYTIC ACTIVITY a 3-oxo-5alpha-steroid + NADP(+) = a 3-oxo-Delta(4)-steroid + NADPH + H(+)CATALYTIC ACTIVITY 17beta-hydroxy-5alpha-androstan-3-one + NADP(+) = testosterone + NADPH + H(+)CATALYTIC ACTIVITY 5alpha-pregnane-3,20-dione + NADP(+) = progesterone + NADPH + H(+)BIOPHYSICOCHEMICAL PROPERTIES Optimally active at acidic pHs.INTERACTION Expressed in high levels in the prostate and many other androgen-sensitive tissues.POLYMORPHISM Individuals with Thr-49 have an increased risk of prostate cancer (PubMed:10501358). The enzyme with Thr-49 has a higher in vitro V(max) than the Ala-49 enzyme (PubMed:10501358).DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the steroid 5-alpha reductase family.ONLINE INFORMATION 5-alpha reductase entry
