An androgen is any natural or synthetic steroid hormone that regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors. The major androgen in males is testosterone. It is the primary sex hormone and anabolic steroid in males. It is a steroid from the androstane class. It exerts its action through binding to and activation of the androgen receptor.

Androgen receptor. Ligand binding domain (LBD) containing an active site which binds intramolecularly the N-terminal FXXFL motif or coactivators with the same motif.^[1] Water molecules are shown as red spheres. Human androgen receptor bound to testosterone (2ylo).
Heat shock factor (HSF) are transcriptional activators of heat shock genes. HSF bind to heat shock sequence elements throughout the genome with a consensus array of three oppositely oriented sequence AGGAN and activate transcription. Each HSF monomer contains one C-terminal and 3 N-terminal leucine zippers. Two sequences flanking the N-terminal leucine zippers contain the consensus nuclear localization signal (NLS). The DNA-binding domain (DBD residues 193-281) of HSF lies in the N-terminal of the first NLS region^[2]. Depletion of HSF-1 is associated with accumulation of pathogenic androgen receptor in neurodegenerative diseases^[3].
Cellular retinoic acid-binding protein (CRABP); Epididymal RABP (ERABP) is an androgen-dependent RABP present in the lumen of the epididymis believed to be involved in sperm maturation. ERABP binds specifically all-trans- and 9-cis-RA.
Aromatase. The primary function of aromatase is to produce estrogens by aromatizing androgens. Aromatase is the only known enzyme in vertebrates capable of catalyzing the aromatization of a six-membered ring^[4].
Student Project 1 for UMass Chemistry 423 Spring 2015. Protein kinase C related kinase 1 (PRK1) is a component of Rho-GTPase, histone demethylase, androgen receptor, and histone demethylase signaling pathways and is involved in ovary and prostate cancer. A lot of PRK1 is expressed in cases of ovarian serous carcinoma.
Finasteride
Zolinza (Vorinostat)
Hydroxysteroid dehydrogenase, 17-β HSD is involved in the conversion of androstenedione to testosterone.
Aromatase converts androstenedione to estrogen and testosterone to estradiol.
Lipids: structure and classification
Cytochrome P450 3A4 (CYP3A4)
