"PPP1R9A" - Neurabin-1 in Homo sapiens
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

PPP1R9ANeurabin-1; Binds to actin filaments (F-actin) and shows cross- linking activity. Binds along the sides of the F-actin. May be involved in neurite formation. Inhibits protein phosphatase 1- alpha activity (By similarity); PDZ domain containing (1374 aa)    
Predicted Functional Partners:
PPP1CA
Serine/threonine-protein phosphatase PP1-alpha catalytic subunit; Protein phosphatase that associates with over 200 regulatory proteins to form highly specific holoenzymes which dephosphorylate hundreds of biological targets. Protein phosphatase 1 (PP1) is essential for cell division, and participates in the regulation of glycogen metabolism, muscle contractility and protein synthesis. Involved in regulation of ionic conductances and long-term synaptic plasticity. May play an important role in dephosphorylating substrates such as the postsynaptic density-associated Ca(2+)/calmodulin de [...] (341 aa)
     
 
  0.883
SGCE
Epsilon-sarcoglycan; Component of the sarcoglycan complex, a subcomplex of the dystrophin-glycoprotein complex which forms a link between the F-actin cytoskeleton and the extracellular matrix (462 aa)
     
   
  0.828
NRG4
Pro-neuregulin-4, membrane-bound isoform; Low affinity ligand for the ERBB4 tyrosine kinase receptor. Concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. Does not bind to the ERBB1, ERBB2 and ERBB3 receptors (By similarity) (115 aa)
           
  0.711
MARCH7
E3 ubiquitin-protein ligase MARCH7; E3 ubiquitin-protein ligase which may specifically enhance the E2 activity of HIP2. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfer the ubiquitin to targeted substrates; Membrane associated ring-CH-type fingers (704 aa)
           
  0.711
NAP1L5
Nucleosome assembly protein 1 like 5 (182 aa)
     
   
  0.706
RPL23
Ribosomal protein L23 (140 aa)
     
        0.668
NRG3
Pro-neuregulin-3, membrane-bound isoform; Direct ligand for the ERBB4 tyrosine kinase receptor. Binding results in ligand-stimulated tyrosine phosphorylation and activation of the receptor. Does not bind to the EGF receptor, ERBB2 or ERBB3 receptors. May be a survival factor for oligodendrocytes; Belongs to the neuregulin family (696 aa)
     
   
  0.666
ASB4
Ankyrin repeat and SOCS box protein 4; Probable substrate-recognition component of a SCF-like ECS (Elongin-Cullin-SOCS-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Promotes differentiation and maturation of the vascular lineage by an oxygen-dependent mechanism (By similarity); Belongs to the ankyrin SOCS box (ASB) family (426 aa)
       
 
  0.659
PVALB
Parvalbumin alpha; In muscle, parvalbumin is thought to be involved in relaxation after contraction. It binds two calcium ions; EF-hand domain containing (110 aa)
     
   
  0.648
NRG2
Pro-neuregulin-2, membrane-bound isoform; Direct ligand for ERBB3 and ERBB4 tyrosine kinase receptors. Concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. May also promote the heterodimerization with the EGF receptor; Belongs to the neuregulin family (850 aa)
