STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

PPP4R1Serine/threonine-protein phosphatase 4 regulatory subunit 1 isoform X1. (939 aa)    
Predicted Functional Partners:
PPP4C
Serine/threonine-protein phosphatase.
   
 0.936
PPP2R5D
Serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit; The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment.
   
 0.838
PPP2R2B
Serine/threonine-protein phosphatase 2A 55 kDa regulatory subunit B; Belongs to the phosphatase 2A regulatory subunit B family.
   
 0.811
PPP4R3B
Serine/threonine-protein phosphatase 4 regulatory subunit 3B.
   
 
 0.807
PPP2CA
Serine/threonine-protein phosphatase.
   
 0.803
PPP2R2A
Serine/threonine-protein phosphatase 2A 55 kDa regulatory subunit B; Belongs to the phosphatase 2A regulatory subunit B family.
   
 0.789
PPP4R3A
LOW QUALITY PROTEIN: serine/threonine-protein phosphatase 4 regulatory subunit 3A.
   
  
 0.746
PTPA
Serine/threonine-protein phosphatase 2A activator; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.
   
 0.725
PPP2R5C
Serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit; The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment.
   
 0.724
PPP2R5E
Serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit; The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment.
