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

ash1Histone-lysine N-methyltransferase ash1; Trithorax group (TrxG) protein that has histone methyltransferase activity. Specifically trimethylates 'Lys-4' of histone H3 (H3K4me3), a specific tag for epigenetic transcriptional activation. TrxG proteins are generally required to maintain the transcriptionally active state of homeotic genes throughout development. Does not act as a coactivator required for transcriptional activation, but specifically prevents inappropriate Polycomb Group (PcG) silencing of homeotic genes in cells in which they must stay transcriptionally active. Belongs to t [...] (2226 aa)    
Predicted Functional Partners:
MRG15
NuA4 complex subunit EAF3 homolog; Part of the Tip60 chromatin-remodeling complex which is involved in DNA repair. Upon induction of DNA double-strand breaks, this complex acetylates phosphorylated H2AV in nucleosomes and exchanges it with unmodified H2AV.

puf
Ubiquitin carboxyl-terminal hydrolase puf; Ubiquitin hydrolase that can remove conjugated ubiquitin from target proteins and polyubiquitin chains. Essential for Myc-mediated cell growth and proliferation in developing eyes and wings. In the wing and eye, the deubiquitinating activity acts as an antagonist to the SCF E3 ubiquitin-protein ligase member archipelago (ago) to regulate Myc and CycE stability and thus control cell growth and proliferation. Also appears to regulate ago by modulating its induction by Myc. May also promote cell apoptosis in the wing imaginal disk, acting in an a [...]

CG10947
FI04554p; S-adenosylmethionine-dependent methyltransferase activity; calmodulin-lysine N-methyltransferase activity. It is involved in the biological process described with: regulation of translation.
     
 0.916
Plod
Procollagen-lysine,2-oxoglutarate 5-dioxygenase; Procollagen lysyl hydroxylase (Plod) encodes a lysyl dehydrogenase with roles in Collagen IV biosynthesis. It localizes to the endoplasmic reticulum and is required for the secretion Collagen IV from haemocytes and fat body.

Set2
Probable histone-lysine N-methyltransferase CG1716; Probable histone methyltransferase. Histone methylation gives specific tags for epigenetic transcriptional activation or repression (By similarity).
   
  
0.894
trx
Histone-lysine N-methyltransferase trithorax; Histone methyltransferase that trimethylates 'Lys-9' of histone H3 (H3K9me3). H3 'Lys-9' methylation represents a specific tag for epigenetic transcriptional activation. Functions in segment determination through interaction with genes of bithorax (BX-C) and antennapedia (ANT-C) complexes. Acts as an activator of BX-C. Involved in the very early regulation of homeotic genes expressed only in the posterior region of the embryo.
   
 
0.868
Br140
Bromodomain-containing protein, 140kD (Br140) encodes a histone acetyltransferase that is a component of the Enok complex, which interacts with the product of elg1 via Br140 to promote the G1/S transition via proliferating cell nuclear antigen (PCNA) unloading.
   
 
 0.846
His3:CG31613
Histone H3; Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.
   
 
 0.807
E(bx)
Nucleosome-remodeling factor subunit NURF301; Histone-binding component of NURF (nucleosome remodeling factor), a complex which catalyzes ATP-dependent nucleosome sliding and facilitates transcription of chromatin. Specifically recognizes H3 tails trimethylated on 'Lys-4' (H3K4me3), which mark transcription start sites of virtually all active genes. Required for homeotic gene expression, proper larval blood cell development, normal male X chromosome morphology, ecdysteroid signaling and metamorphosis. Belongs to the BPTF family.
   
 
 0.793
msl-3
Protein male-specific lethal-3; Male-specific lethal 3 (msl-3) encodes a chromodomain protein, reported to interact with H3K36me3, H4K20me1 and DNA. It is a member of the Male-Specific-Lethal dosage compensation complex, which increases male X chromosome transcription approximately two-fold. Homozygous mutant males die as larvae, while females are viable.
