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

HProtein hairless; Is a potent antagonist of neurogenic gene activity during sensory organ development. The expression of distinct cell fates by the trichogen (shaft) / tormogen (socket) sister cell pair depends on the level of H activity. A certain threshold level of H activity is required, below which both sister cells adopt the tormogen fate. (1077 aa)    
Predicted Functional Partners:
Su(H)
Suppressor of hairless protein; Transcriptional regulator that plays a central role in Notch signaling, a signaling pathway involved in cell-cell communication that regulates a broad spectrum of cell-fate determinations. Binds directly the 5'-GTGRGAR-3' DNA consensus sequence, which is present in the regulatory region of several genes. Acts as a transcriptional repressor when it is not associated with Notch proteins. When associated with some Notch protein, it acts as a transcriptional activator that activates transcription of Notch target genes. Required for transcription of Sim. Spec [...]

gro
Groucho (gro) encodes a global developmental co-repressor in conjunction with manifold DNA-binding repressor partner proteins, which tether it to target promoters. It functions downstream of key signaling pathways such as Wg/Wnt and Dpp/TGF-beta. Notably, phosphorylation of the product of gro in response to MAPK activation weakens its repressor capacity.
   
 0.988
CtBP
C-terminal-binding protein; Corepressor targeting diverse transcription regulators. Hairy-interacting protein required for embryonic segmentation and hairy-mediated transcriptional repression; Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family.
   
 0.988
N
Processed neurogenic locus Notch protein; Essential signaling protein which has a major role in many developmental processes. Functions as a receptor for membrane-bound ligands Delta and Serrate to regulate cell-fate determination. Upon ligand activation, and releasing from the cell membrane, the Notch intracellular domain (NICD) forms a transcriptional activator complex with Su(H) (Suppressor of hairless) and activates genes of the E(spl) complex. Regulates oogenesis, the differentiation of the ectoderm and the development of the central and peripheral nervous system, eye, wing disk, [...]

HDAC1
Histone deacetylase HDAC1; Catalyzes the deacetylation of lysine residues on the N- terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation may constitute a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. For instance, deacetylation of histone H3 may be a prerequisite for the subsequent recruitment of the histone methyltransferase Su(var)3-9 to histones. Involved in position-effect variegation (PEV). In the larval brain, part of a regulatory network including the transcript [...]

Mad
Mothers against dpp (Mad) encodes the primary transcription factor that mediates cellular response to the BMP like ligands encoded by dpp, scw and gbb. Upon phosphorylation by either the products of sax or tkv (type I BMP receptors), it forms a complex with the product of Med and translocates to the nucleus where, together with cofactors, it regulates expression of BMP response target genes; Belongs to the dwarfin/SMAD family.

insv
Protein insensitive; Can act as both a transcriptional repressor and corepressor. Represses the expression of genes involved in neural development and preferentially binds palindromic sequence 5'-CCAATTGG-3' to mediate transcriptional repression. Acts as a corepressor for suppressor of hairless (Su(H)) and inhibits Notch signaling during peripheral nervous system development.

shn
Schnurri, isoform F; Schnurri (shn) encodes a zinc finger C2H2 transcription factor involved in Dpp signaling. It contributes to multiple processes including ectoderm and midgut development, wing disc patterning and morphogenesis of Malpighian tubules and dendrites.
   
 
  0.732
Med
Mothers against decapentaplegic homolog; Medea (Med) encodes a protein that belongs to the highly conserved Smad family. It can bind its siblings encoded by Mad or Smox to facilitate signal transduction for the product of dpp or Activin ligands in the TGF-beta family. Med-complexes function as transcriptional regulators. Many developmental roles include dorsal-ventral patterning, patterning and proliferation of the wing disc and gene expression in the mushroom body of the larval brain.
   
 
  0.724
Dl
Neurogenic locus protein delta; Acts as a ligand for Notch (N) receptor. Essential for proper differentiation of ectoderm. Dl is required for the correct separation of neural and epidermal cell lineages. Fringe (fng) acts in the Golgi to determine the type of O-linked fucose on the EGF modules in N, altering the ability of N to bind with Delta (Dl). O-fut1 also has a role in modulating the interaction.
