ATP-dependent RNA helicase DHH1 - P39517 (DHH1_YEAST)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P39517: 3
ATP-dependent RNA helicase involved in mRNA turnover, and more specifically in mRNA decapping by activating the decapping enzyme DCP1 (PubMed:11780629, PubMed:12032091, PubMed:11696541, PubMed:12730603, PubMed:15703442. PubMed:15706350). Is involved in G1/S DNA-damage checkpoint recovery, probably through the regulation of the translational status of a subset of mRNAs (PubMed:15166134). May also have a role in translation and mRNA nuclear export (PubMed:12930949). Required for sporulation (PubMed:12930949). Blocks autophagy in nutrient-rich conditions by, at least partly, binding and repressing the expression of a set of ATG genes, including ATG3, ATG7, ATG8, ATG19, ATG20, ATG22 and SNX4/ATG24 (PubMed:26098573).

Subunit Structure
Associated with the CCR4-NOT complex and possibly other big complexes (PubMed:9504907, PubMed:12930949). Interacts with CDC39/NOT1 (PubMed:11696541). Interacts with DCP1, LSM1, and POP2 (PubMed:9504907, PubMed:11780629). Interacts with IGO1 (PubMed:20471941). Interacts with PAT1 and with KEM1, the major 5'-3' exonuclease (PubMed:11780629, PubMed:12032091). UniProt
The Q motif is unique to and characteristic of the DEAD box family of RNA helicases and controls ATP binding and hydrolysis. UniProt

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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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