ID:FOXA2_HUMAN DESCRIPTION: RecName: Full=Hepatocyte nuclear factor 3-beta; Short=HNF-3-beta; Short=HNF-3B; AltName: Full=Forkhead box protein A2; AltName: Full=Transcription factor 3B; Short=TCF-3B; FUNCTION: Transcription factor that is involved in embryonic development, establishment of tissue-specific gene expression and regulation of gene expression in differentiated tissues. Is thought to act as a 'pioneer' factor opening the compacted chromatin for other proteins through interactions with nucleosomal core histones and thereby replacing linker histones at target enhancer and/or promoter sites. Binds DNA with the consensus sequence 5'-[AC]A[AT]T[AG]TT[GT][AG][CT]T[CT]-3' (By similarity). In embryonic development is required for notochord formation. Involved in the development of multiple endoderm-derived organ systems such as the liver, pancreas and lungs; FOXA1 and FOXA2 seem to have at least in part redundant roles. Originally described as a transcription activator for a number of liver genes such as AFP, albumin, tyrosine aminotransferase, PEPCK, etc. Interacts with the cis-acting regulatory regions of these genes. Involved in glucose homeostasis; regulates the expression of genes important for glucose sensing in pancreatic beta-cells and glucose homeostasis. Involved in regulation of fat metabolism. Binds to fibrinogen beta promoter and is involved in IL6-induced fibrinogen beta transcriptional activation. SUBUNIT: Binds DNA as a monomer. Binds TLE1 (By similarity). Interacts with FOXA1 and FOXA3. Interacts with PRKDC. SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Shuttles between the nucleus and cytoplasm in a CRM1-dependent manner; in response to insulin signaling via AKT1 is exported from the nucleus. PTM: Phosphorylation on Thr-156 abolishes binding to target promoters and subsequent transcription activation upon insulin stimulation (By similarity). SIMILARITY: Contains 1 fork-head DNA-binding domain. SEQUENCE CAUTION: Sequence=AAH11780.1; Type=Erroneous initiation; Note=Translation N-terminally extended; WEB RESOURCE: Name=Wikipedia; Note=Hepatocyte nuclear factors entry; URL="http://en.wikipedia.org/wiki/Hepatocyte_nuclear_factors";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
