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

trxHistone-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. (3726 aa)    
Predicted Functional Partners:
ash2
Set1/Ash2 histone methyltransferase complex subunit ASH2; Transcriptional regulator. Regulates a number of genes involved in wing development including activation of net and bs and repression of rho and kni and controls vein-intervein patterning during wing development. Required for correct expression of a number of homeotic genes including Scr in the first leg imaginal disk and Ubx in the third leg imaginal disk and haltere disks. Required for stabilization of the histone-lysine N-methyltransferase trr and for trimethylation of 'Lys-4' of histone H3. Plays a role in maintenance of tra [...]

Rbbp5
Retinoblastoma-binding protein 5 homolog; Component of the SET1 complex that specifically di- and trimethylates 'Lys-4' of histone H3 and of the MLL3/4 complex which also methylates histone H3 'Lys-4'.
    
 0.995
Mnn1
Menin 1 (Mnn1) encodes a protein that regulates the response of several stresses including hypoxia, hyperosmolarity, heat shock, and oxidative stress. It is important during the mitotic G1 DNA damage checkpoint in a process mediated by the product of CHES-1-like.

Sbf
SET domain binding factor, isoform A.

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.
   
 0.959
cyp33
Peptidyl-prolyl cis-trans isomerase E; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Combines RNA-binding and PPIase activities (By similarity); Belongs to the cyclophilin-type PPIase family. PPIase E subfamily.
    
 
 0.956
nej
Nejire, isoform C; Nejire (nej) encodes the transcriptional co-activator CBP. It acetylates several nuclear proteins, including the histone encoded by His3 on K18, K27, and H4 on K8. By regulating gene expression, the product of nej has roles in cell proliferation, cell signaling and differentiation, and in developmental patterning.
   
 0.955
ear
ENL/AF9-related, isoform B; ENL/AF9-related (ear) encodes a transcription factor that is a component of the super elongation complex (SEC), which regulates transcription by RNA Polymerase II. It also interacts with the histone methyltransferase encoded by gpp in the Dot1 complex (DotCom), which modifies chromatin structure by methylating histone H3 on lysine 79.
    
 0.930
Dpy-30L1
Dpy-30-like 1 (Dpy-30L1) encodes a protein that is part of the COMPASS complex, a histone H3K4 methyltransferase complex thought to be responsible for the bulk of the histone H3K4 di- and trimethylation. The product of Dpy-30L1 binds to, and thereby inhibits, the metal-responsive transcription factor encoded by MTF-1.
    
 0.912
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.
