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.

Upf2RE04053p; Upf2 (Upf2) encodes a protein required for nonsense-mediated mRNA decay (NMD). It interacts directly with the product of Upf1 to identify and degrade NMD-substrate mRNAs, including mRNAs containing premature termination codons and a number of normal endogenous mRNAs. (1241 aa)    
Predicted Functional Partners:
Upf3
Upf3, isoform B; Upf3 (Upf3) encodes a protein that regulates targets of the nonsense-mediated mRNA decay pathway. This pathway participates in homeostatic gene expression regulation and plays a quality control role in the elimination of mRNAs with premature termination codons. The product of Upf3 is involved in cell cycle progression and general developmental rate.

Upf1
Regulator of nonsense transcripts 1 homolog; RNA-dependent helicase and ATPase required for nonsense- mediated decay (NMD) of mRNAs containing premature stop codons. Is recruited to mRNAs upon translation termination and undergoes a cycle of phosphorylation and dephosphorylation; its phosphorylation appears to be a key step in NMD. The formation of an Upf1-Upf2-Upf3 surveillance complex is believed to activate NMD (By similarity).

nonC
Serine/threonine-protein kinase Smg1; Serine/threonine protein kinase involved in mRNA surveillance. Recognizes the substrate consensus sequence [ST]-Q. Involved in nonsense-mediated decay (NMD) of mRNAs containing premature stop codons, probably by phosphorylating Upf1.

RnpS1
RNA-binding protein S1 (RnpS1) encodes a protein involved in RNA splicing and regulation of DNA transposition.
    
 0.998
tsu
RNA-binding protein 8A; Core component of the splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junctions on mRNAs. Involved in exon definition of genes containing long introns, including the rolled/MAPK gene. The mago-tsu heterodimer interacts with the EJC key regulator Pym leading to EJC disassembly in the cytoplasm. Has a role in oskar mRNA localization to the posterior pole of the developing oocyte. Belongs to the RBM8A family.

Srrm1
FI04407p; SRm160 (SRm160) encodes a conserved RNA-binding protein that participates in the exon junction complex and is involved in pre-mRNA splicing and 3' end formation. It participates in somatic sex determination, cell death, retinal development and the control of circadian rhythm. Direct targets include rl.
   
 0.997
btz
Barentsz, isoform D; Barentsz (btz) encodes a component of the exon junction complex that is recruited to spliced mRNAs to mark where introns have been removed. It is required for the posterior localization of osk mRNA.
    
 0.996
mago
Protein mago nashi; Core component of the splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junctions on mRNAs. Involved in exon definition of genes containing long introns, including the rolled/MAPK gene. The mago-tsu heterodimer interacts with the EJC key regulator Pym leading to EJC disassembly in the cytoplasm. Has a role in oskar mRNA localization to the posterior pole of the developing oocyte, and may also be involved in polarization of the oocyte microtubule cytoskeleton.

CG7483
Eukaryotic initiation factor 4A-III; ATP-dependent RNA helicase. Core component of the splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junctions on mRNAs. Involved in exon definition of genes containing long introns, including the rolled/MAPK gene. Has a role in oskar mRNA localization at the posterior pole of the developing oocyte.

Smg6
GH14566p; Smg6 (Smg6) encodes an RNA endonuclease that is required for nonsense mediated mRNA decay (NMD). Upon recognition of an NMD-targeted transcript, it cleaves the mRNA in the vicinity of the termination codon, exposing free 5' and 3' ends leading to the complete exonucleolytic degradation of the target.
