Function

A cytochrome P450 monooxygenase involved in corticoid and androgen biosynthesis (PubMed:9452426, PubMed:27339894, PubMed:22266943, PubMed:25301938). Catalyzes 17-alpha hydroxylation of C21 steroids, which is common for both pathways. A second oxidative step, required only for androgen synthesis, involves an acyl-carbon cleavage. The 17-alpha hydroxy intermediates, as part of adrenal glucocorticoids biosynthesis pathway, are precursors of cortisol (PubMed:9452426, PubMed:25301938) (Probable). Hydroxylates steroid hormones, pregnenolone and progesterone to form 17-alpha hydroxy metabolites, followed by the cleavage of the C17-C20 bond to form C19 steroids, dehydroepiandrosterone (DHEA) and androstenedione (PubMed:9452426, PubMed:27339894, PubMed:22266943, PubMed:25301938). Has 16-alpha hydroxylase activity. Catalyzes 16-alpha hydroxylation of 17-alpha hydroxy pregnenolone, followed by the cleavage of the C17-C20 bond to form 16-alpha-hydroxy DHEA. Also 16-alpha hydroxylates androgens, relevant for estriol synthesis (PubMed:27339894, PubMed:25301938). 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) (PubMed:9452426, PubMed:27339894, PubMed:22266943, PubMed:25301938).

Activity summary

Cytochrome P450 17A1 also known as CYP17A1 is an essential enzyme in the steroidogenic pathway. Its molecular mass is approximately 57 kDa. It is part of the cytochrome P450 family and shows expression primarily in the adrenal glands and gonads. This enzyme catalyzes two key reactions: the 17α-hydroxylation of pregnenolone and progesterone and the subsequent 1720-lyase reaction. These reactions are critical for the production of steroid hormones such as glucocorticoids and sex steroids.

Biological function summary

CYP17A1 plays a central role in hormone biosynthesis. The enzyme exists as a single protein and does not form part of a larger complex. By facilitating the conversion of progestogens into androgens it directly impacts the balance and levels of steroid hormones in the body. This function supports vital processes like the development of secondary sexual characteristics and the regulation of metabolism therefore affecting multiple physiological functions.

Pathways

CYP17A1 integrates into both the steroidogenesis and biosynthesis pathways of adrenal and sex hormones. It links directly with proteins such as steroidogenic acute regulatory protein (StAR) and cytochrome P450 oxidoreductase (POR) which assist in enabling its enzymatic function. These pathways regulate the levels of hormones influencing biological processes including stress responses and reproductive functions.

Associated diseases and disorders

CYP17A1 is associated with conditions like congenital adrenal hyperplasia and prostate cancer. In congenital adrenal hyperplasia CYP17A1 mutations disrupt the steroidogenesis pathway leading to cortisol production deficiency. In prostate cancer CYP17A1 is often upregulated contributing to increased androgen levels that fuel cancer progression. Proteins such as 3β-hydroxysteroid dehydrogenase (3β-HSD) and androgen receptor (AR) interact with CYP17A1 in these disorders demonstrating its importance in disease mechanisms.

    Overlay histogram showing HeLa cells stained with ab203743 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab203743, 1/50 dilution) for 30 min at 22°C. Isotype control antibody (black line) was rabbit monoclonal IgG [EPR25A] Alexa Fluor® 647 (Alexa Fluor® 647 Rabbit IgG, monoclonal [EPR25A] - Isotype Control ab199093) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a solid-state 25mW red diode laser (635 nm) and 675/30 bandpass filter. This antibody gave a positive signal in HeLa cells fixed with 4% formaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
