ID:GT2D1_HUMAN DESCRIPTION: RecName: Full=General transcription factor II-I repeat domain-containing protein 1; Short=GTF2I repeat domain-containing protein 1; AltName: Full=General transcription factor III; AltName: Full=MusTRD1/BEN; AltName: Full=Muscle TFII-I repeat domain-containing protein 1; AltName: Full=Slow-muscle-fiber enhancer-binding protein; AltName: Full=USE B1-binding protein; AltName: Full=Williams-Beuren syndrome chromosomal region 11 protein; AltName: Full=Williams-Beuren syndrome chromosomal region 12 protein; FUNCTION: May be a transcription regulator involved in cell-cycle progression and skeletal muscle differentiation. May repress GTF2I transcriptional functions, by preventing its nuclear residency, or by inhibiting its transcriptional activation. May contribute to slow-twitch fiber type specificity during myogenesis and in regenerating muscles. Binds troponin I slow-muscle fiber enhancer (USE B1). Binds specifically and with high affinity to the EFG sequences derived from the early enhancer of HOXC8 (By similarity). SUBUNIT: Interacts with the retinoblastoma protein (RB1) via its C-terminus. SUBCELLULAR LOCATION: Nucleus. TISSUE SPECIFICITY: Highly expressed in adult skeletal muscle, heart, fibroblast, bone and fetal tissues. Expressed at lower levels in all other tissues tested. DEVELOPMENTAL STAGE: Highly expressed in developing and regenerating muscles, at the time of myofiber diversification. DOMAIN: The N-terminal half may have an activating activity. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. DISEASE: Note=GTF2IRD1 is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region. Haploinsufficiency of GTF2IRD1 may be the cause of certain cardiovascular and musculo-skeletal abnormalities observed in the disease. SIMILARITY: Belongs to the TFII-I family. SIMILARITY: Contains 5 GTF2I-like repeats.
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.
