These proteins take vitamin A from blood to gene regulation: RBP4 carries retinol, STRA6 takes it into cells, LRAT stores it, RDH10 and the ALDH1A enzymes turn it into retinoic acid (DHRS3 reverses the first step), CRABP2 carries retinoic acid to the nucleus, the RAR and RXR receptors act on it, and CYP26A1 and CYP26B1 break it down. Isotretinoin, the drug behind post-retinoid sexual dysfunction, is a retinoid; and several retinol dehydrogenases (RDH16, HSD17B6, RDH5) also oxidize androgen metabolites such as 3α-androstanediol, a point of contact with the steroid pathways implicated in PFS.
