Protein Structures

check button PDB and CIF files of the predicted protein structures
* Here we show the 3D structure of the proteins using Mol*. AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Model confidence is shown from the pLDDT values per residue. pLDDT corresponds to the model’s prediction of its score on the local Distance Difference Test. It is a measure of local accuracy (from AlphfaFold website). To color code individual residues, we transformed individual PDB files into CIF format.

PPARG12588773A functional polymorphism in a STAT5B site of the human PPAR gamma 3 gene promoter affects height and lipid metabolism in a French population.The peroxisome proliferator-activated receptor-gamma (PPARgamma) plays a role in adipocyte differentiation and insulin sensitization. It has been shown that genetic variation in the PPARgamma gene alters body weight control, lipid and insulin homeostasis, and the susceptibility to type 2 diabetes. Four PPARgamma isoforms are generated by alternative splicing and promoter usage. PPARgamma3 is only expressed in adipose tissue, colon, and macrophages and therefore seems to be a good candidate gene for metabolic and cardiovascular-associated diseases. In the present study, we looked for genetic variation in the PPARgamma3 promoter.D008052Lipid Metabolism, Inborn Errors
PPARG16180511The difference of mutation in the peroxisome proliferator activated receptor gamma2 gene among people at high altitudes and low altitudes in Bolivia.Peroxisome proliferator activated receptor (PPAR) gamma is present in two isoforms generated by alternative splicing, PPAR gamma 1 and PPAR gamma 2. A Pro12Ala polymorphism in human PPAR gamma 2 moderately reduces its transcriptional activity, and thus PPAR gamma 2 is thought to be a promising candidate gene for several human disorders, including obesity and type 2 diabetes mellitus. In this report, we examined the polymorphism of the PPAR gamma 2 gene in people at high and low altitudes in Bolivia, and found a significant difference in the frequency of Ala carriers (Pro/Ala and Ala/Ala) between 153 native high-altitude Bolivian subjects (64.1%) and 288 low-altitude Bolivian subjects (37.9%). The frequency of this Ala allele in Bolivian subjects was fairly higher than that in other ethnic groups. As body mass index, however, was not associated with Pro12Ala polymorphism of the PPAR gamma 2 gene among either the high altitude Bolivians or low altitude Bolivians, Pro12Ala polymorphism of the gene has little relationship to obesity in Bolivians.D009765Obesity
PPARG16513680Peroxisome proliferator-activated receptor (PPAR) gamma gene polymorphisms and colorectal cancer risk among Chinese in Singapore.Peroxisome proliferator-activated receptor (PPAR) gamma is a ligand-activated nuclear receptor that plays a key role in adipogenesis and adipocyte gene expression, and has recently been linked with possible antineoplastic effects in colonic carcinogenesis. PPARgamma2 and gamma3 are two transcripts arising from the PPARgamma gene through differential promoter usage and alternative splicing. We investigated the associations between PPARgamma2 Pro12Ala and PPARgamma3 C-681G gene polymorphisms and colorectal cancer (CRC) risk in a case-control study nested within the Singapore Chinese Health Study. Genotypes for the PPARgamma2 and PPARgamma3 polymorphisms were determined on 362 incident CRC cases and 1164 cohort controls by direct sequencing and by fluorogenic 5'-nuclease assay. Unconditional logistic regression models were used for statistical analyses. With adjustment for CRC risk factors, subjects with one or two copies of the G allele of the PPARgamma2 Pro12Ala polymorphism showed a statistically significant reduction in risk compared to those with the CC genotype [odds ratio (OR)=0.53, 95% confidence interval (CI)=0.30-0.92]. For the PPARgamma3 C-681G polymorphism, subjects with one or two copies of the C allele showed a reduction in risk compared to those with the GG genotype (OR=0.72, 95% CI=0.51-1.04). When PPARgamma2 and PPARgamma3 genotypes were considered simultaneously, the number of putative low-risk genotypes was significantly associated with reduced risk of CRC in a gene-dose-dependent manner; the OR (95% CI) was 0.72 (0.49-1.07) among subjects possessing one low-risk genotype (either PPARgamma2 or PPARgamma3), and the comparable figure among subjects possessing both low-risk genotypes was 0.19 (0.07-0.51).D015179Colorectal Neoplasms

PPARG20403997Genetic variation in 3-hydroxy-3-methylglutaryl CoA reductase modifies the chemopreventive activity of statins for colorectal cancer.Genetic variation in 3-hydroxy-3-methylglutaryl CoA reductase (HMGCR), the rate-limiting enzyme in cholesterol synthesis, modifies the effect of statins on serum cholesterol levels. Long-term use of statins is associated with a reduced risk of colorectal cancer (CRC) in some, but not all, studies. We genotyped variants in 40 candidate genes important for cholesterol synthesis and metabolism in a population-based case-control study of CRC involving 2,138 incident cases and 2,049 population-based controls. We identified a single-nucleotide polymorphism in the HMGCR gene that significantly modified the protective association between statins and CRC risk. Compared with nonusers, the unadjusted odds ratio of CRC among statin users with the A/A genotype of rs12654264 in HMGCR was 0.3 (95% confidence interval, 0.18-0.51) and among statin users with the T/T genotype was 0.66 (95% confidence interval, 0.41-1.06; P-interaction = 0.0012). This genetic variant (A/A genotype of rs12654264) also was associated with lower serum levels of low-density lipoprotein among all cases and controls. In colon cancer cell lines, the reduction in cholesterol levels after statin treatment was substantially stronger in cells carrying the A/A genotype, and this difference was related to alternative splicing involving the HMGCR statin-binding domain. We anticipate that these data may advance the development of personalized statin use for reducing the risk of cancer as well as cardiovascular disease among the approximately 25 million people currently using statins worldwide.D015179Colorectal Neoplasms
