SRD5A3 - steroid 5 alpha-reductase 3 Gene
Also Known as S5AR; CDG1P; CDG1Q; KRIZI; S5AR 3; SRD5A2L; SRD5A2L1
Species: Homo sapiens
About SRD5A3
This gene has 8 transcripts (splice variants), 201 orthologues and is associated with 4 phenotypes. Ubiquitous expression in gall bladder (RPKM 7.7), endometrium (RPKM 4.5) and 25 other tissues.
Summary
The protein encoded by this gene belongs to the steroid 5-alpha reductase family, and polyprenol reductase subfamily. It is involved in the production of androgen 5-alpha-dihydrotestosterone (DHT) from testosterone, and maintenance of the androgen-androgen receptor activation pathway. This protein is also necessary for the conversion of polyprenol into dolichol, which is required for the synthesis of dolichol-linked Monosaccharides and the oligosaccharide precursor used for N-linked glycosylation of proteins. Mutations in this gene are associated with congenital disorder of glycosylation type Iq. [provided by RefSeq, Mar 2011]
