HNF4A | Hepatocyte nuclear factor 4-alpha; Transcriptional regulator which controls the expression of hepatic genes during the transition of endodermal cells to hepatic progenitor cells, facilitating the recruitment of RNA pol II to the promoters of target genes. Activates the transcription of CYP2C38 (By similarity). Represses the CLOCK- ARNTL/BMAL1 transcriptional activity and is essential for circadian rhythm maintenance and period regulation in the liver and colon cells. (474 aa) | ||||
CYP2W1 | Cytochrome P450 2W1; Seems to have broad catalytic activity towards several chemicals, including polycyclic aromatic hydrocarbon dihydrodiols and aromatic amines. Active also in the metabolism of indoline substrates and is able to activate aflatoxin B1 into cytotoxic products. Furthermore, it seems to be involved in the oxydation of lysophospholipids and fatty acids. Belongs to the cytochrome P450 family. (490 aa) |
