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

pen-2Gamma-secretase subunit pen-2; Essential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch. It probably represents the last step of maturation of gamma-secretase, facilitating endoproteolysis of presenilin and conferring gamma-secretase activity. (101 aa)    
Predicted Functional Partners:
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.
    
 0.999
Nct
Nicastrin; Essential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch. It probably represents a stabilizing cofactor required for the assembly of the gamma-secretase complex.
   
 0.999
aph-1
Gamma-secretase subunit Aph-1; Anterior pharynx defective 1 (aph-1) encodes a scaffolding subunit of the gamma-secretase complex together with the products of Psn, Nct and pen-2. It is involved in several Notch related processes such as differentiation, cellular organization and developmental patterning via gamma-secretase proteolitic function.
   
 0.998
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, [...]

kuz
Kuzbanian, isoform A; Kuzbanian (kuz) encodes an ADAM metalloendopeptidase that regulates activation of the receptors encoded by N and robo1 by cleavage.
    
 
 0.868
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.
    
 
 0.868
Fur2
Furin-like protease 2; Furin is likely to represent the ubiquitous endoprotease activity within constitutive secretory pathways and capable of cleavage at the RX(K/R)R consensus motif.
      
 0.689
Fur1
Furin-like protease 1, isoforms 1/1-X/2; Furin is likely to represent the ubiquitous endoprotease activity within constitutive secretory pathways and capable of cleavage at the RX(K/R)R consensus motif.
      
 0.688
Alp1
Alkaline phosphatase 1, isoform B; Alkaline phosphatase 1 (Alp1) encodes an alkaline phosphatase. Alkaline phosphatases catalyze the hydrolysis of monoesters of phosphoric acid and a transphosphorylation reaction in the presence of large concentrations of phosphate acceptors.
      
 0.657
Ser
Protein 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.
