Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q9LQT8: 2
Transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. Transcription coactivator of the zinc finger transcription factors GAF1/IDD2 and ENY/IDD1 in regulation of gibberellin homeostasis and signaling (PubMed:25035403). No effect of the BOI proteins on its stability. Probably acts by participating in large multiprotein complexes that repress transcription of GA-inducible genes. Positively regulates XERICO expression. In contrast to RGA, it is less sensitive to GA. Its activity is probably regulated by other phytohormones such as auxin and ethylene. UniProt

Subunit Structure
Interacts directly with the GID2/SLY1 component of the SCF(GID2) complex. Interacts (via N-terminus) with GID1A, GID1B and GID1B (via N-terminus). Interacts with the BOI proteins BOI, BRG1, BRG2, BRG3 and NUP58 (PubMed:15155881, PubMed:15161962, PubMed:15173565, PubMed:16709201, PubMed:19037309, PubMed:23482857, PubMed:23840761). Interacts with TOPP4 (PubMed:25010794, PubMed:15155881, PubMed:15161962, PubMed:15173565, PubMed:16709201, PubMed:19037309, PubMed:23482857, PubMed:23840761). Interacts with TCP14 and TCP15 (PubMed:25655823). Interacts with FLZ5 (Ref.25). Binds to and coactivates GAF1/IDD2 and ENY/IDD1 at the promoter of GA20OX2 gene (PubMed:25035403). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
