Tyrosine-protein phosphatase non-receptor type 13 - Q12923 (PTN13_HUMAN)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Tyrosine phosphatase which regulates negatively FAS-induced apoptosis and NGFR-mediated pro-apoptotic signaling (PubMed:15611135). May regulate phosphoinositide 3-kinase (PI3K) signaling through dephosphorylation of PIK3R2 (PubMed:23604317). UniProt

Subunit Structure
Interacts (via the first PDZ domain) with PLEKHA1 and PLEKHA2 (PubMed:14516276). Interacts (via the second PDZ domain) with TNFRSF6 (Fas receptor) (via C-terminus) (PubMed:10704206). Interacts (via the second PDZ domain) with TRIP6 (via the third LIM domain and C-terminus) (PubMed:10826496, PubMed:10400701). Interacts (via the third PDZ domain) with NGFR (via C-terminal SVP motif) and PKN2 (via C-terminus) (PubMed:10544233, PubMed:11356191). Interacts (via the second or fourth PDZ domains) with PDLIM4 (via C-terminus only or via combined C-terminus and LIM domain, but not LIM domain only). Found in a complex with PDLIM4 and TRIP6 (By similarity). Interacts with PDLIM4; this interaction results in dephosphorylation of SRC 'Tyr-419' by this protein leading to its inactivation (PubMed:19307596). Interacts with BRD7 (By similarity). Interacts with RAPGEF6 (PubMed:12095257). Interacts with ARHGAP29 (PubMed:9305890). Interacts with PIK3R2; dephosphorylates PIK3R2 (PubMed:23604317). Interacts with FBXL2 (PubMed:23604317). Interacts (via the FERM domain) with ENTR1 (PubMed:23108400). Found in a complex with ENTR1, PTPN13 and GIT1 (PubMed:23108400). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
