  • Number of PDB entries for P42128: 2
 
Function
Transcriptional regulator that binds to the upstream enhancer region (CCAC box) of myoglobin gene. Important regulatory factor of the myogenic progenitor cell population. Involved in the cell cycle process, promotes proliferation by repressing Foxo4 transcriptional activity and the cyclin-dependent kinase inhibitor, p21CIP, in the myogenic progenitor cells. Represses myogenic differentiation by inhibiting MEFC activity. Has a role in remodeling processes of adult muscles that occur in response to physiological stimuli. Required to correct temporal orchestration of molecular and cellular events necessary for muscle repair (PubMed:10792059). Positively regulates Wnt/beta-catenin signaling by translocating DVL into the nucleus. UniProt

Subunit Structure
Interacts with SIN3A and SIN3B (via PAH2) to form a complex which represses transcription (PubMed:10620510). Interacts with FOXO4 and MEF2C; both interactions inhibit FOXO4 and MEF2C transactivation activity (PubMed:22956541). Interacts with DVL2 and DVL3; the interaction induces DVL2 nuclear translocation.

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
