HSD17B13
hydroxysteroid 17-beta dehydrogenase 13
Pathway candidate — not linked to PFS or PSSD by any record here
Gene summary
A protein-coding gene on chromosome 4 (steroid hormone synthesis). Predicted to enable oxidoreductase activity, acting on the CH-OH group of donors, NAD or NADP as acceptor and steroid dehydrogenase activity. Acts upstream of or within positive regulation of lipid biosynthetic process.

Protein reference (UniProt)
- Protein
17-beta-hydroxysteroid dehydrogenase 13
- Function
Plays a pivotal role in hepatic lipid metabolism. In vitro, it catalyzes the oxidation of a variety of lipid substrates, including 17beta-estradiol, retinol, retinal, and leukotriene B4.
- Subcellular location
Lipid droplet; Endoplasmic reticulum; Cytoplasm.
- Tissue specificity
Highly expressed in the liver. Also detected in ovary, bone marrow, kidney, brain, lung, skeletal muscle, bladder and testis.

Why its pathway is in the library
Steroid-synthesis enzymes sit directly on the pathways perturbed by 5-alpha-reductase inhibitors and SSRIs; inherited variation here is a candidate susceptibility factor for persistent post-drug phenotypes.
Written for the whole steroid synthesis family, not for HSD17B13 specifically.
Mentioned in 0 corpus records
No corpus record names HSD17B13 directly yet. It is in the library because it sits in a pathway the corpus tracks (Steroid synthesis).
