Research Backgrounds

Function:

A cytochrome P450 monooxygenase that catalyzes the conversion of C19 androgens, androst-4-ene-3,17-dione (androstenedione) and testosterone to the C18 estrogens, estrone and estradiol, respectively. Catalyzes three successive oxidations of C19 androgens: two conventional oxidations at C19 yielding 19-hydroxy and 19-oxo/19-aldehyde derivatives, followed by a third oxidative aromatization step that involves C1-beta hydrogen abstraction combined with cleavage of the C10-C19 bond to yield a phenolic A ring and formic acid. Alternatively, the third oxidative reaction yields a 19-norsteroid and formic acid. Converts dihydrotestosterone to delta1,10-dehydro 19-nordihydrotestosterone and may play a role in homeostasis of this potent androgen. Also displays 2-hydroxylase activity toward estrone. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein reductase).

PTMs:

Phosphorylated in vitro by PKA and PKG/PRKG1. These phosphorylations inhibit the catalytic activity as measured by estrone synthesis from androstenedione (36% decrease for PKA and 30% for PKG/PRKG1).

Fig. 4. ZDHHC17 plays a role in the conversion of androgen to estrogen in GCs. (A) GRM02 cells were transfected with scramble (Scr) or Zdhhc17-specific siRNAs and then treated with DHT (100 nM) for 24 h. Cell lysates were collected to determine the mRNA expression level of Cyp19a1. (B) GRM02 cells were transfected with Zdhhc17-specific siRNAs, and cell lysates were collected to determine the protein expression level of CYP19A1. (C–E) GRM02 cells were transfected with scramble (Scr) or Zdhhc17-specific siRNAs and then supplemented with testosterone (10 ng/mL) for 24 h. Cell supernatants were collected to determine the estradiol levels (C) produced per 1 × 105 cells, testosterone levels (D) produced per 1 × 105 cells and estradiol to testosterone ratios (E).
