Serine/threonine-protein phosphatase 4 regulatory subunit 3 - Q9VFS5 (PP4R3_DROME)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q9VFS5: 1
Regulatory subunit of serine/threonine-protein phosphatase 4. The probable PP4 complex Pp4-19C-PPP4R2r-flfl (PPP4C-PPP4R2-PPP4R3) is required to prevent caspase induced cell death (in vitro). May be involved in DNA damage repair. Key mediator specific for the localization of mira and associated cell fate determinants during both interphase and mitosis. Nuclear Flfl is required to exclude mira/pros from the nucleus when inefficiently bound to the cytoskeleton/cortex, whereas cytosolic or membrane-associated flfl is required for the cortical association and asymmetric localization of mira/pros/brat/stau at metaphase and anaphase.

Subunit Structure
Serine/threonine-protein phosphatase 4 (PP4) occurs in different assemblies of the catalytic and one or more regulatory subunits. Probably part of a PP4 PPP4C-PPP4R2-PPP4R3 complex containing Pp4-19C, PPP4R2r and flfl. Interacts with mira. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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

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.
