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

DlNeurogenic 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. (833 aa)    
Predicted Functional Partners:
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, [...]

neur
Neuralized (neur) encodes an E3 ubiquitin ligase of the RING family. It is part of the Notch signaling pathway, where it is thought to contribute to the endocytosis-dependent activation of the ligand. It also has Notch-independent functions in epithelial morphogenesis.
   
  0.919
mib1
E3 ubiquitin-protein ligase mind-bomb; E3 ubiquitin-protein ligase that mediates ubiquitination of Delta (Dl) and Serrate (Ser) receptors, which act as ligands of Notch proteins. Positively regulates the Notch signaling by ubiquitinating the intracellular domain of Dl and Ser, leading to endocytosis of Dl and Ser receptors. Regulates a subset of Notch signaling events, including wing margin specification, leg segmentation and vein determination, that are distinct from those events requiring neuralize (neur) activity. Also modulates lateral inhibition, a neur- and Dl- dependent signalin [...]

ed
Echinoid, isoform A; Echinoid (ed) encodes a cell adhesion molecule of adherens junctions that mediate cell adhesion/recognition. It participates in multiple signaling pathways including Egfr, Notch and Hippo during organogenesis. It is also required in multiple steps of dorsal closure during embryogenesis.
   
   0.705
H
Protein 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.

rst
Irregular chiasm C-roughest protein; Roughest (rst) encodes a multi-purpose transmembrane protein that is well studied in the fly eye and muscle during development. It interacts with the transmembrane ligand encoded by hbs to guide cell movement.
   
   0.670
sca
Scabrous (sca) encodes a secreted glycoprotein with partial homology to fibrinogen and its relatives. It is a transcriptional target of proneural bHLH proteins and a useful marker for proneural regions and cells. It contributes to neural patterning and interacts with the Notch pathway.
   
   0.659
kuz
Kuzbanian, isoform A; Kuzbanian (kuz) encodes an ADAM metalloendopeptidase that regulates activation of the receptors encoded by N and robo1 by cleavage.
   
 
 0.649
Psn
Presenilin homolog; Probable catalytic subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptor. Required for S3 cleavage of Notch, which releases activated Notch protein from the cell membrane. Involved in the patterning of the optic lobes. Belongs to the peptidase A22A family.
    
 
 0.644
fng
Fringe glycosyltransferase; Glycosyltransferase involved in the elongation of O-linked ligands to activate Notch signaling. Possesses fucose-specific beta- 1,3-N-acetylglucosaminyltransferase activity; extends the O-linked fucose on the Notch EGF repeats. Boundary-specific cell-signaling molecule that is responsible for dorsal-ventral cell interactions during wing development.
