Human Gene TFAP2B (ENST00000393655.4) from GENCODE V41
Description: Homo sapiens transcription factor AP-2 beta (TFAP2B), mRNA. (from RefSeq NM_003221) RefSeq Summary (NM_003221): This gene encodes a member of the AP-2 family of transcription factors. AP-2 proteins form homo- or hetero-dimers with other AP-2 family members and bind specific DNA sequences. They are thought to stimulate cell proliferation and suppress terminal differentiation of specific cell types during embryonic development. Specific AP-2 family members differ in their expression patterns and binding affinity for different promoters. This protein functions as both a transcriptional activator and repressor. Mutations in this gene result in autosomal dominant Char syndrome, suggesting that this gene functions in the differentiation of neural crest cell derivatives. [provided by RefSeq, Jul 2008].

ID:AP2B_HUMAN DESCRIPTION: RecName: Full=Transcription factor AP-2-beta; Short=AP2-beta; AltName: Full=Activating enhancer-binding protein 2-beta; FUNCTION: Sequence-specific DNA-binding protein that interacts with inducible viral and cellular enhancer elements to regulate transcription of selected genes. AP-2 factors bind to the consensus sequence 5'-GCCNNNGGC-3' and activate genes involved in a large spectrum of important biological functions including proper eye, face, body wall, limb and neural tube development. They also suppress a number of genes including MCAM/MUC18, C/EBP alpha and MYC. AP-2-beta appears to be required for normal face and limb development and for proper terminal differentiation and function of renal tubular epithelia. SUBUNIT: Binds DNA as a dimer. Can form homodimers or heterodimers with other AP-2 family members. Interacts with CITED4. Interacts with UBE2I. Interacts with KCTD1; this interaction represses transcription activation. Interacts with CITED2 (via C-terminus); the interaction stimulates TFAP2B-transcriptional activity. SUBCELLULAR LOCATION: Nucleus (Probable). PTM: Sumoylated on Lys-21; which inhibits transcriptional activity (Probable). DISEASE: Defects in TFAP2B are the cause of Char syndrome (CHAR) [MIM:169100]. CHAR is an autosomal dominant disorder characterized by patent ductus arteriosus (PDA), facial dysmorphism and hand anomalies. SIMILARITY: Belongs to the AP-2 family.

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.
ModBase Predicted Comparative 3D Structure on Q92481
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.
