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

POSHPlenty of SH3s (POSH) encodes a scaffold protein that regulates TNF-JNK signaling pathway. (838 aa)    
Predicted Functional Partners:
RpS27A
Ubiquitin-40S ribosomal protein S27a; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is involve [...]

Tak1
Mitogen-activated protein kinase kinase kinase 7; Component of a protein kinase signal transduction cascade. Mediator of TGF-beta signal transduction. Responsible for activation of the JNK MAPK pathway (basket, bsk and hemipterous, hep) in response to LPS. Component of the NF-kappa-B pathway; relish-mediated JNK inhibition involves proteasomal degradation of Tak1; certain targets of Relish that are induced during immune responses may facilitate destruction of Tak1 and switch off the JNK cascade. Participates in diverse roles such as control of cell shape and regulation of apoptosis.

Uxs
UDP-xylose synthase; NAD+ binding; UDP-glucuronate decarboxylase activity.
   
  
 0.704
slmb
Supernumerary limbs (slmb) encodes an essential, conserved F-box protein and a component of the SCF (Skp/Cullin/F-box) E3 ubiquitin-ligase, providing substrate specificity to the SCF. It negatively regulates multiple signaling pathways and cellular processes by promoting the proteasome-mediated degradation or cleavage of its targets, including the products of arm and ci (Wg and Hh signaling), SAK, per and Cap-H2.
    
 
 0.675
Spt-I
Pyridoxal phosphate binding; serine C-palmitoyltransferase activity. It is involved in the biological process described with: positive regulation of sphingolipid biosynthetic process; ceramide biosynthetic process; sphingosine biosynthetic process.
    
 
 0.664
Tab2
TAK1-associated binding protein 2 (Tab2) encodes a protein with an ubiquitin binding domain. It interacts with the product of Tak1, a MAP kinase kinase kinase involved the activation of the immune deficiency, JNK and Grindelwald-Eiger pathways.
   
 
 0.647
CdGAPr
Cd GTPase activating protein-related (CdGAPr) encodes a protein that acts in concert with the product of Fak in the formation of the optic stalk, a tubular structure composed of glial cells.
      
 0.630
scny
Ubiquitin carboxyl-terminal hydrolase 36; Hydrolase that deubiquitinates polyubiquitinated target proteins including imd. Required for preventing the constitutive activation of the imd/NF-kappa-B (Imd) signaling cascade under unchalleneged conditions. Deubiquitinates imd linked 'Lys-63' chains which leads its proteasomal degradation and consequently down-regulation of the Imd signaling cascade. Removal of the activating 'Lys-63'-linked chains is likely to enable their replacement with 'Lys- 48'-linked chains which act as 'tags' the for proteosomal degradation of imd. Required for maint [...]

Xe7
Xe7, isoform A; Xe7 (Xe7) encodes a protein that contributes to axon guidance and lateral inhibition.
      
 0.627
Ubi-p63E
Polyubiquitin; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is involved in protein degradatio [...]
