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

SerProtein serrate; Acts as a ligand for Notch (N) receptor. Essential for proper ectodermal development. Serrate represents an element in a network of interacting molecules operating at the cell surface during the differentiation of certain tissues. (1407 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, [...]

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 [...]

numb
Numb (numb) encodes a membrane-associated inhibitor of Notch signaling. It controls neuroblast and sense organ precursor asymmetric division. It is asymmetrically localized during mitosis and segregates exclusively to one of two daughter cells.
   
 
 0.878
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 [...]

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.
   
 
 0.860
kuz
Kuzbanian, isoform A; Kuzbanian (kuz) encodes an ADAM metalloendopeptidase that regulates activation of the receptors encoded by N and robo1 by cleavage.
   
 
 0.842
Hey
Hairy/E(spl)-related with YRPW motif (Hey) encodes a transcription factor involved in neuron fate determination. Hey expression is regulated by Notch signalling in the embryonic and larval central nervous system.
   
  
 0.842
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.
    
 0.840
Dll
Homeotic protein distal-less; Transcription factor that plays a role in larval and adult appendage development. Specifies the identity of ventral appendages (including legs and antennae) and suppresses dorsal appendage development. Involved in patterning the distal-proximal limb axis. May control the adhesive properties of cells during limb morphogenesis. Also has a secondary role in the normal patterning of the wing margin.
   
  
 0.839
Kul
Kuzbanian-like, isoform A; Kuzbanian-like (Kul) encodes an ADAM metalloprotease involved in regulation of the Notch signaling pathway by cleaving the product of Dl.
