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

aosProtein giant-lens; Regulates cell determination; development of ommatidia and optic lobe. Is a signaling molecule involved in the process of axon pathfinding in the eye. Part of the Ras pathway regulating programmed cell death in pupal eyes; activated by lozenge (lz). Antagonist for the Egfr receptor (gurken). Inhibits Egfr signaling without interacting directly with the receptor, but instead by sequestering the Egfr- activating ligand spitz (spi). (444 aa)    
Predicted Functional Partners:
Egfr
Epidermal growth factor receptor; Binds to four ligands: Spitz, Gurken, Vein and Argos, which is an antagonist. Transduces the signal through the ras-raf-MAPK pathway. Involved in a myriad of developmental decisions. Critical for the proliferation of imaginal tissues, and for the determination of both the antero-posterior and dorso-ventral polarities of the oocyte. In the embryo, plays a role in the establishment of ventral cell fates, maintenance of amnioserosa and ventral neuroectodermal cells, germ band retraction, cell fate specification in the central nervous system and production [...]

spi
Protein spitz; Ligand for the EGF receptor (Gurken). Involved in a number of unrelated developmental choices, for example, dorsal-ventral axis formation, glial migration, sensory organ determination, and muscle development. It is required for photoreceptor determination.
   
 0.986
rho
Protein rhomboid; Acts early in embryonic development to establish position along the dorsoventral axis and then again later to specify the fate of neuronal precursor cells. Involved in EGF receptor signaling; cleaves Spitz to release the active growth factor. Belongs to the peptidase S54 family.
   
 
 0.903
Ras85D
Ras-like protein 1; Ras proteins bind GDP/GTP and possess intrinsic GTPase activity (By similarity). Plays a role in eye development by regulating cell growth, survival of postmitotic ommatidial cells and differentiation of photoreceptor cells. During larval development, mediates Ptth/tor signaling leading to the production of ecdysone, a hormone required for the initiation of metamorphosis.
    
 
 0.839
pnt
ETS-like protein pointed; ETS transcription factor with a prominent role during development of the eye and the nervous system. Required for glial- neuronal cell interactions at the ventral midline which are necessary for the proper elaboration of commissures in the embryonic CNS. [Isoform P1]: Required for normal EGFR-induced photoreceptor development. Following transcriptional activation by isoform P2, acts as a constitutive activator of transcription, leading to induction of target genes essential for photoreceptor development. In larval brains, involved in the maintenance of type II [...]
   
 
 0.735
sty
Protein sprouty; Inhibitor of tracheal branching that restricts branch budding by antagonizing the BNL-FGF pathway (BNL: branchless, an fgf inducer of branching). Acts as an antagonist of EGFR-mediated signaling in the eye (where it is important for cell determination) midline glia, chordotonal organs, wing and ovarian follicle cells.
   
   0.704
aop
Ets DNA-binding protein pokkuri; Anterior open (aop) encodes a transcriptional repressor of the ETS family. It acts downstream of receptor tyrosine kinase signaling to regulate cell fate transitions critical to the development of many tissues including the nervous system, heart, trachea and eye.
   
  
 0.683
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.
    
 
 0.631
kek1
Kekkon 1 (kek1) encodes a transmembrane protein that acts in a negative feedback loop to modulate the activity of the product of Egfr in a number of tissues, including follicle cells and imaginal discs. It also plays a role in axonal outgrowth in the central nervous system.
      
 0.625
S
Star (S) encodes a type II transmembrane protein that facilitates trafficking of transmembrane Egfr ligands from the endoplasmic reticulum to the late secretory compartment. It is involved in growth regulation, cell survival and developmental patterning.
