ID:TCF21_HUMAN DESCRIPTION: RecName: Full=Transcription factor 21; Short=TCF-21; AltName: Full=Capsulin; AltName: Full=Class A basic helix-loop-helix protein 23; Short=bHLHa23; AltName: Full=Epicardin; AltName: Full=Podocyte-expressed 1; Short=Pod-1; FUNCTION: Involved in epithelial-mesenchymal interactions in kidney and lung morphogenesis that include epithelial differentiation and branching morphogenesis. May play a role in the specification or differentiation of one or more subsets of epicardial cell types. SUBUNIT: Efficient DNA binding requires dimerization with another bHLH protein. Forms a heterodimer with TCF3 and binds the E box (5'-CANNTG-3'). SUBCELLULAR LOCATION: Nucleus. SIMILARITY: Contains 1 bHLH (basic helix-loop-helix) domain.
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.
