Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P34707: 1
Transcription factor required to specify the fate of ventral blastomeres in the early embryo, and postembryonically for the development of the intestine. Directly regulates expression of zygotically expressed med-1 and med-2 to direct mesendoderm development (PubMed:1547503, PubMed:11463373). Required for stl-1 mRNA up-regulation in response to oxidative stress and anoxia. Required for the up-regulation of gcs-1 and several glutathione-S-transferase mRNAs in response to oxidative stress generated during pathogenic bacterial infection (PubMed:22216003). In neurons, involved in mitochondrial fusion and behavioral recovery during reoxygenation (PubMed:24385935). Required for riok-1 mRNA expression in the intestine (PubMed:25688864). Downstream of the let-60/Ras, mek-2 and pmk-1 pathway, positively regulates lifespan probably by preventing transcription of insulin-like peptides such as ins-39 (PubMed:20624915). Prevents degeneration of dopaminergic CEP neurons in response to high Al(3+) or Mn(2+) levels, probably by promoting the expression of glutathione-S-transferase gst-1 (PubMed:23106139, PubMed:23721876).

Subunit Structure
Monomer. UniProt
Alternative DNA-binding strategy due to lack of a leucine zipper dimerization segment: DNA binding domain binds to its cognate half-site, an N-terminal arm recognizes adjacent 5' AT-rich sequences in the minor groove and the intervening residues stabilize interactions of these two subdomains with DNA.

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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
