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

dxProtein deltex; Regulator of Notch signaling, a signaling pathway involved in cell-cell communications that regulates a broad spectrum of cell-fate determinations. Mainly acts as a positive regulator of Notch, but it may also act as a negative regulator, depending on the developmental and cell context. Mediates the antineural activity of Notch. May function as a ubiquitin ligase protein in the Notch pathway. Belongs to the Deltex family. (738 aa)    
Predicted Functional Partners:
Su(dx)
E3 ubiquitin-protein ligase Su(dx); E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Down-regulates Notch/N signaling pathway, probably by promoting Notch ubiquitination, endocytosis and degradation. Involved in wing growth and leg joint formation.

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, [...]

krz
Kurtz, isoform A; Kurtz (krz) encodes a beta-arrestin (non-visual arrestin) involved in the desensitization and endocytic internalization of G protein coupled receptors, thus downregulating their activity. It also controls other signaling pathways, including Notch, receptor tyrosine kinase, Hedgehog, and Toll. It is required maternally for normal embryonic patterning and zygotically for larval viability.
    
 0.823
mam
Neurogenic protein mastermind; Mastermind (mam) encodes a transcriptional coactivator that functions in the Notch signaling pathway. It regulates gene expression by interacting with the intracellular domain of the product of N, which is produced upon receptor activation.
    
 
 0.733
RpS27A
Ubiquitin-40S ribosomal protein S27a; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is involve [...]

dap
RE12958p; Dacapo (dap) encodes a Cyclin-dependent kinase inhibitor in the CIP/KIP family. It binds to CycE-Cdk2 complexes and thereby inhibits their protein kinase activity. Upregulation of dap is required after the last mitosis for arresting cells in G1/G0 before terminal differentiation in many post-mitotic cell types.
   
   0.663
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.
   
  
 0.622
Ank
Ankyrin, isoform B; Ankyrin (Ank) encodes protein that is recruited to the plasma membrane by its association with the product of beta-Spec. It also binds to the adhesion protein encoded by Nrg leading to accumulation of the products of Ank and beta-Spec at sites of cell-cell adhesion.
    
 
 0.622
Ank2
Ankyrin 2, isoform U; Ankyrin 2 (Ank2) encodes a cytoskeletal binding protein required for proper function of the product of beta-Spec via direct interaction. It contributes to the regulation of short-term memory, sound perception, microtubule cytoskeleton and neuromuscular junction development and synapsis.
    
 
 0.622
Ubi-p5E
Ubiquitin-5E, isoform A; Protein tag; ubiquitin protein ligase binding. It is involved in the biological process described with: ubiquitin-dependent protein catabolic process; protein ubiquitination; modification-dependent protein catabolic process; cellular protein modification process.
