Protein Gawky - Q8SY33 (GAWKY_DROME)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q8SY33: 1
Required for gene silencing mediated by micro-RNAs (miRNAs). Silences both polyadenylated and deadenylated mRNAs. Required for miRNA-mediated translational repression and mRNA decay. Not required for miRNA target recognition. Necessary to initiate but not to maintain silencing. Promotes mRNA deadenylation through the recruitment of the CCR4-NOT and PAN complexes and promotes decapping by the DCP1-DCP2 complex. Dissociates from silenced mRNAs after deadenylation. Required for completion of nuclear divisions during early embryonic development. UniProt

Subunit Structure
Interacts (via N-terminal region) with AGO1 (via Piwi domain); the interaction is essential for localization of AGO1 in P-bodies and for miRNA-mediated silencing. Interacts with pAbp/PABPC1; this interaction interferes with the binding of pAbp to eIF4G and is required for miRNA-mediated silencing. Interacts with CCR4-NOT complex members Not1, Rga/NOT2, twin/CCR4, Pop2 and NOT3/5 and with PAN complex members CG8232/PAN2 and CG11486/PAN3. UniProt
The RRM domain lacks RNA-binding properties and does not bind RNA in vitro. It is not required for P-body localization or for interaction with AGO1 or miRNAs but is required for silencing. May play a role in protein-protein interactions. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
