Ankyrin repeat domain-containing protein A238L - O36972 (VF238_ASFM2)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for O36972: 1
IkB-like protein that inhibits the binding of NF-kappa-B to DNA, thereby downregulating proinflammatory cytokine production (PubMed:8970976). Forms a heterodimer with the NF-kappa-B subunit RELA/p65 and prevents the activation of the NF-kappa-B transcription factor (By similarity). Inhibits calcineurin function, which is required for the induction of nuclear factor of activated T cells (NFAT)-dependent immune response genes (PubMed:23468591, PubMed:9677199). Prevents the binding of substrates to calcineurin without affecting the phosphatase activity (PubMed:23468591). Does not contain the serine residues that are phosphorylated by host IkB kinase and thus is not degraded following stimulation of the NFkB pathway. UniProt

Subunit Structure
Interacts with host PPIA (PubMed:9677199). Interacts with host PPP3CA/Calcineurin (PubMed:9677199, PubMed:11000210, PubMed:23468591). Interacts with host RELA/p65; interaction of the 32 kDa form with host RELA results in the formation of a stable complex with NF-kappa-B (By similarity). Interacts with host PPP3R1 (PubMed:23468591). Interacts with host EP300; this interaction inhibits the association of host EP300 with host RELA, JUN and NFATC2. UniProt
The C-terminal region contains the docking motifs PxIxITxC and FLCV, which are required and sufficient for binding to host calcineurin. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
