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

rho-4Rhomboid-4, isoform A; Rhomboid-4 (rho-4) encodes a member of the rhomboid superfamily of intramembrane serine proteases, which cleave to release proteins from the membrane. It processes the transmembrane EGF ligands encoded by spi, Krn, and grk. Its activity is directly and dramatically stimulated by calcium; Belongs to the peptidase S54 family. (417 aa)    
Predicted Functional Partners:
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.
   
 
 0.738
grk
Protein gurken; Critical for defining the anterior-posterior and dorsal- ventral axes of the egg. May signal directly to dorsal follicle cells through the receptor torpedo (top). During oogenesis this signaling pathway instructs follicle cells to follow a dorsal pathway of development rather than the default ventral pathway.
    
 
 0.674
RhoGAP92B
Rho GTPase-activating protein 92B; GTPase activator for the Rho-type GTPases by converting them to an inactive GDP-bound state.
   
  
 0.521
Pmm2
Probable phosphomannomutase; Involved in the synthesis of the GDP-mannose and dolichol- phosphate-mannose required for a number of critical mannosyl transfer reactions.
   
  
 0.499
CG32320
DC_STAMP domain-containing protein.
      
 0.495
Krn
LD34429p; Keren (Krn) encodes an ligand for the receptor encoded by Egfr that is processed by the products of S and rho. It shows a redundant role with the products of spi in very few tissues.
    
   0.469
S2P
Metalloendopeptidase activity. It is involved in the biological process described with: positive regulation of transcription from RNA polymerase II promoter in response to endoplasmic reticulum stress; sterol regulatory element binding protein cleavage; membrane protein intracellular domain proteolysis; positive regulation of DNA-binding transcription factor activity.
  
  
 0.437
Sema1b
Chemorepellent activity; semaphorin receptor binding; Belongs to the semaphorin family.
   
  
 0.435
Rho1
Ras-like GTP-binding protein Rho1; Has a role in regulating actin cytoskeletal organization: required during early development for proper execution of morphogenetic movements of individual cells and groups of cells important for the formation of the embryonic body plan. Plays a role in regulating dorsal closure during embryogenesis. During axis elongation, required for Rho-kinase Rok planar polarity and adherens junction localization as well as for generating a planar polarized distribution of the actin-binding protein Shrm. During embryogenesis, acts upstream of wash to regulate the d [...]
   
  
 0.435
Scp2
Cex Ca2+-sensing low molecular weight GTPase; GTPase activity; calcium ion binding.
      
 0.422
