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

pho2aSerine/threonine-protein phosphatase 2A catalytic subunit A; Plays a role in activating the myosin contractile function. Dephosphorylates threonine at 'Thr-1823', 'Thr-1833' and 'Thr-2029' in the C-terminal tail region of myosin II heavy chain (mhcA). Drives the assembly of dephosphorylated myosin II filaments to allow myosin recruitment into the cytoskeleton. (306 aa)    
Predicted Functional Partners:
psrA
Serine/threonine-protein phosphatase 2A regulatory subunit psrA; Involved in developmental cell fate decision. Belongs to the phosphatase 2A regulatory subunit B56 family.

DDB0205957
Uncharacterized protein.

DDB0219848
Uncharacterized protein.
   
 0.991
phr2aB
Serine/threonine-protein phosphatase 2A regulatory subunit phr2AB; 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.
   
 0.991
DDB0206306
EF-hand domain-containing protein.
    
 0.989
ppp2r4A
Probable serine/threonine-protein phosphatase 2A activator 1; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Acts as a regulatory subunit for PP2A-like phosphatases modulating their activity or substrate specificity, probably by inducing a conformational change in the catalytic subunit, a direct target of the PPIase (By similarity).
    
 0.989
pppA
Protein phosphatase 2A scaffold subunit; Scaffolding molecule which may coordinate the assembly of the catalytic subunit and a variable regulatory B subunit. Component of the Sca1 complex, a regulator of cell motility, chemotaxis and signal relay. The Sca1 complex is recruited to the plasma membrane in a chemoattractant- and F-actin-dependent manner and is enriched at the leading edge of chemotaxing cells where it regulates F-actin dynamics and signal relay by controlling the activation of rasC and the downstream target of rapamycin complex 2 (TORC2)-Akt/protein kinase B (PKB) pathway.
   
 0.986
ppme1
Probable protein phosphatase methylesterase 1; Demethylates proteins that have been reversibly carboxymethylated; Belongs to the AB hydrolase superfamily.

DDB0205063
Uncharacterized protein.

ppp2r4B
Probable serine/threonine-protein phosphatase 2A activator 2; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Acts as a regulatory subunit for PP2A-like phosphatases modulating their activity or substrate specificity, probably by inducing a conformational change in the catalytic subunit, a direct target of the PPIase (By similarity).
