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

PlexAPlexin A (PlexA) encodes a transmembrane receptor for Semaphorin ligands encoded by Sema1a and Sema1b. The intracellular region of this receptor has GTPase activating protein (GAP) activity on Ras/Rap small GTPases. The signaling by the product of PlexA alters actin, microtubules and cell adhesion in developmental processes such as axon guidance. (1945 aa)    
Predicted Functional Partners:
Sema1b
Chemorepellent activity; semaphorin receptor binding; Belongs to the semaphorin family.
   
 0.999
Sema1a
Semaphorin-1A; Semaphorin 1a (Sema1a) encodes a transmembrane protein belonging to the semaphorin protein family. It is a repulsive axon guidance cue, signaling through direct interactions with the receptor encoded by PlexA, and also functions as a receptor to regulate dendrite targeting and axon guidance. Secreted semaphorins encoded by Sema2a and Sema2b can act as the product of Sema1a ligands.
   
0.999
Sema2a
Semaphorin-2A; Semaphorin 2a (Sema2a) encodes a secreted member of the semaphorin protein family. It utilizes the receptor encoded by PlexB to mediate both repulsive and attractive axon guidance. It also utilizes the transmembrane semaphorin encoded by Sema1a as a receptor for dendrite process guidance.
   
 0.987
Mical
[F-actin]-monooxygenase Mical; Monooxygenase that promotes depolymerization of F-actin by mediating oxidation of specific methionine residues on actin. Acts by modifying actin subunits at 'Met-44' and 'Met-47' through the addition of oxygen to form methionine-sulfoxide, leading to promote actin filament disassembly and prevent repolymerization. Plays a key role in semaphorin-plexin repulsive axon guidance and cell morphological changes, probably via its ability to modify and regulate actin. Belongs to the Mical family.
    
 
 0.970
Sema5c
Semaphorin 5c (Sema5c) encodes a member of the Semaphorins family, which are membrane and secreted short-range signaling proteins. The product of Sema5c is involved in olfactory behavior.
   
0.965
Sema2b
Semaphorin 2b (Sema2b) encodes a member of the Semaphorins family, which are membrane and secreted short-range signaling proteins. The product of Sema2b contributes to the regulation of axon and dendrite guidance as well as cell-matrix adhesion.
    
 0.963
otk
Tyrosine-protein kinase-like otk; Acts as a calcium-dependent, homophilic cell adhesion molecule that regulates neural recognition during the development of the nervous system. Component of the repulsive Plexin signaling response to regulate motor axon guidance at the embryonic stage. Also component of a receptor complex that is required in the adult visual system to innervate the lamina layer; specific targeting of R1-R6 axons; Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
    
 
 0.960
PlexB
Plexin-B; Involved in peripheral and central nervous system axon guidance. Acts as a receptor for Sema-2a and seems to transduce signal by suppressing Rac activity and enhancing Rho activity. Belongs to the plexin family.
  
0.934
Ephrin
Ephrin, isoform A; Ephrin (Ephrin) encodes the ligand of the product of Eph. It is involved in nervous system development; Belongs to the ephrin family.
  
  
 0.876
CG42637
Receptor-type guanylate cyclase Gyc76C; Guanylate cyclase involved in the production of the second messenger cGMP. Acts as a receptor for the NPLP1-4 peptide and modulates the innate immune IMD pathway in response to salt stress by inducing nuclear translocation of NF-kappa-B protein Rel which leads to increased expression of the antimicrobial peptide diptericin. Plays a role in Sema-1a-mediated axon repulsion which is required for the correct establishment of neuromuscular connectivity. Required in developing embryonic somatic muscle for correct patterning of ventral and lateral muscl [...]
