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

Mmp2Matrix metalloproteinase-2; Has metalloproteinase activity. Required for larval tissue histolysis during metamorphosis and is involved in pupal head eversion and fusion of the wing imaginal tissue. Required for growth of the dorsal air sac primordium and development of the dorsal air sacs. Promotes embryonic motor axon fasciculation. Cleaves and activates frac to promote motor axon bundling during outgrowth. Promotes the reshaping of adult sensory neuron dendrites from a radial to lattice-like shape which occurs after eclosion by degrading the basement membrane on which the dendrites g [...] (758 aa)    
Predicted Functional Partners:
Timp
Tissue inhibitor of metalloproteinase; Metalloproteinase inhibitor that acts on both matrix metalloproteinases Mmp1 and Mmp2 in vitro. Complexes with metalloproteinases and irreversibly inactivates them by binding to their catalytic zinc cofactor (By similarity). Required for wing maturation which is the final step in morphogenesis of the adult fly. Involved in the negative regulation of developmental tissue invasion for imaginal disk eversion during metamorphosis by inhibiting Mmp-mediated basement membrane (BM) degradation. Required for oogenesis and for the long-term maintainance of [...]

Mmp1
Matrix metalloproteinase 1 (Mmp1) encodes a proteinase that cleaves proteins in the extracellular matrix. It is involved in tissue histolysis and remodeling during metamorphosis, tracheal remodeling, wound healing, wing regeneration, neoplastic growth, and circadian behavior. It has been used as a reporter for JNK signaling since it is upregulated by the pathway.
  
0.947
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.
   
 0.865
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, [...]

vkg
Viking, isoform A; Viking (vkg) encodes a subunit of Collagen IV and a major component of basement membranes. It is secreted by haemocytes and fat body cells and is required for the normal morphogenesis of many tissues. It also contributes to TGF-beta signalling in the early embryo and the developing Malpighian tubules.
   
 
 0.803
arr
Low-density lipoprotein receptor-related protein; Arrow (arr) encodes a type I trans-membrane protein and functions as an obligate co-receptor with the product of fz for the ligand encoded by wg in the canonical Wnt signaling pathway. The product of arr is involved in developmental patterning, cell survival and growth regulation; Belongs to the LDLR family.
   
 0.788
Pkc53E
Protein kinase C, brain isozyme; PKC is activated by diacylglycerol which in turn phosphorylates a range of cellular proteins (By similarity). PKC also serves as the receptor for phorbol esters, a class of tumor promoters (By similarity). Acts in a hh-signaling pathway which regulates the Duox-dependent gut immune response to bacterial uracil; required for the activation of Cad99C and consequently Cad99C-dependent endosome formation, which is essential for the Duox-dependent production of reactive oxygen species (ROS) in response to intestinal bacterial infection ; Belongs to the prote [...]

shg
DE-cadherin; Cadherins are calcium-dependent cell adhesion proteins. In connecting cells they preferentially interact with themselves in a homophilic manner; cadherins may thus contribute to the sorting of heterogeneous cell types. During oogenesis, integral component of the guidance mechanisms that regulate the directional persistent collective migration of the border cell (BC) cluster through the nurse cells to the oocyte. Functions downstream of the two chemoattractant receptors, Pvr and Egfr, to promote BC adhesion between the leader cells of the migrating cluster and the surroundi [...]

CG11912
Peptidase S1 domain-containing protein; Serine-type endopeptidase activity. It is involved in the biological process described with: proteolysis; Belongs to the peptidase S1 family.
   
 0.754
frac
Faulty attraction (frac) encodes an extracellular matrix protein that acts via an LIMK1- dependent BMP pathway to promote axon target recognition. The product of frac might be a proteolytic substrate of the matrix metalloproteinase encoded by Mmp2.
