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.

vnVein (vn) encodes a secreted neuregulin-like EGFR ligand. It has weaker intrinsic activity, and a lower receptor affinity, than the TGFalpha-like ligand encoded by spi. It has roles in growth and patterning of tissues including muscle, midgut, ovary, trachea, glia, eye, leg, and wing. (623 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 [...]
   
 0.999
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.
    
 
 0.960
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.
   
   0.945
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.
    
 0.846
Shc
SHC-adaptor protein (Shc) encodes a protein involved in receptor tyrosine kinase signalling. It regulates anti-parasitoid immune response and tracheal development.
     
 0.806
aos
Protein 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).
   
   0.742
Pi3K21B
Pi3K21B, isoform B; Pi3K21B (Pi3K21B) encodes an adaptor protein (p60) that binds the product of Pi3K92E to form the functional cllass IA phosphoinositide 3-kinase. This heterodimeric kinase is involved in phosphatidylinositol phosphorylation and regulates cell size and proliferation.
     
 0.719
elgi
Early girl (elgi) encodes a myosin binding protein involved in the regulation of meiosis and Fat signaling pathway.
    
 0.715
csw
Tyrosine-protein phosphatase corkscrew; Required in all receptor tyrosine kinase signaling pathways. Functions downstream of the receptor tyrosine kinase torso, acting in concert with D-Raf via tailless. Also functions downstream of Egfr (epidermal growth factor receptor) and btl (fibroblast growth factor receptor). The SH2 domain suggests that csw effects its role by mediating heteromeric protein interactions. Maternally required for normal determination of cell fates at the termini of the embryo. Required for cell fate specification of the ventral ectoderm, in the developing embryoni [...]
   
   0.701
CG13344
Uncharacterized protein, isoform A; Zinc ion binding; ubiquitin-protein transferase activity; ubiquitin protein ligase activity. It is involved in the biological process described with: positive regulation of NF-kappaB transcription factor activity; protein ubiquitination.
