SYSTEMATIC NAME
IUBMB Comments
sterol,NADPH:oxygen oxidoreductase (14-methyl cleaving)
This heme-thiolate (P-450) enzyme acts on a range of steroids with a 14alpha-methyl group, such as obtusifoliol and lanosterol. The enzyme catalyses two successive hydroxylations of the 14alpha-methyl group, followed by elimination as formate, leaving a 14(15) double bond.

siRNA
-
administrated single dose of 10 microg CYP51-siRNAs for 48 h results in significantly depletion of CYP51 mRNA in liver of mice fed on normal diet (from 40 to 60%). Exerts inhibition in a dose dependent manner (from 26% in 5 microg to 40% in 20 microg). Most inhibitive effect from day 3 to day 6 (over 50%) after treatment. Six days after administration of 30 microg CYP51-siRNAs (20 microg on day 0 and 10 microg on day 3), CYP51 mRNA and protein levels are significantly knocked down in mice liver. Low-density lipoprotein receptor expression is significantly elevated compared with controls in hepatic cells after CYP51-siRNAs. As a consequence, about 50% of sera low-density lipoprotein cholesterol are significantly reduced. Effect on low-density lipoprotein receptor increase and low-density lipoprotein cholesterol reduction lasts 8 days after a single 20 microg CYP51-siRNAs injection. CYP51-siRNAs can not cause any fatty liver compared with buffer-group and do not interfere with mice ovulation

Aspergillus fumigatus CYP51A and CYP51B both complement Saccharomyces cerevisiae sterol 14alpha-demethylase function with comparable efficiency. In the presence of doxycycline, recombinant YUG37-pcyp51A and YUG37-pcyp51B yeasts are able to synthesize ergosterol and grow, a control strain harboring reverse-oriented cyp51A cannot. YUG37-pcyp51A and YUG37-pcyp51B constructs show identical sensitivity to itraconazole, posaconazole, clotrimazole, voriconazole, and fluconazole

the genes are located on chromosomes 3, 7, and 13, the gene on chromosome 7 is the functional one while those on chromosomes 3 and 13 are processed pseudogenes which arise from reverse transcription of mRNA in germ cells and illegitimate recombination into the genome, CYP51 responds to cholesterol feedback regulation, being upregulated in sterol limiting conditions and downregulated in cholesterol rich conditions, regulation involves the sterol regulatory elements SRE in the promoter of the gene which bind sterol regulatory element binding protein, SREBP, the CYP51 promoter also contains a cAMP regulatory element, CRE, binding cAMP regulatory proteins CREB/CREM

LITERATURE
expressed in baculovirus and in Escherichia coli
expression of both isoform CYP51A and CYP51B is significantly induced by exposure to sterol demethylation inhibitor fungicides tebuconazole, propiconazole, and prochloraz
LDM expression is induced in the uterine stroma under artificial decidualisation. Oestrogen, but not progesterone, treatment induces a high level of LDM expression in the uterus of ovariectomised mice
-
transcription of AcCYP51 increases in various culture conditions including adding squalene, lanosterol, itroconazole, and oleic acid as inducers. Itroconazol, a fungicide that targets CYP51 and as an inhibitor causes the accumulation of lanosterol and reduced ergosterol biosynthesis in fungi, also induces AcCYP51 expression after 24 h of treatment
