Tax1-binding protein 3 - O14907 (TX1B3_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for O14907: 9
May regulate a number of protein-protein interactions by competing for PDZ domain binding sites. Binds CTNNB1 and may thereby act as an inhibitor of the Wnt signaling pathway. Competes with LIN7A for KCNJ4 binding, and thereby promotes KCNJ4 internalization. May play a role in the Rho signaling pathway. May play a role in activation of CDC42 by the viral protein HPV16 E6. (data source: UniProt  )
Subunit structure
Interacts (via its PDZ domain) with GLS2. Interacts (via its PDZ domain) with RTKN (via the C-terminal region); this interaction facilitates Rho-mediated activation of the FOS serum response element (SRE). Interacts (via its PDZ domain) with CTNNB1; this interaction inhibits the transcriptional activity of CTNNB1. Interacts with HTLV-1 TAX protein. Interacts (via PDZ domain) with ARHGEF16. Interacts (via PDZ domain) with KCNJ4 (via C-terminus). Competes with LIN7A for KCNJ4 binding. Interacts with ADGRB2 (PubMed:21787750). (data source: UniProt  )

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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 terminus of a PDB sequence. To get more information about the meaning and exact position of a sequence modification, move your mouse over the icon.
