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

IGSF21Immunoglobulin superfamily member 21; Involved in synaptic inhibition in the brain. Selectively regulates inhibitory presynaptic differentiation through interacting with presynaptic NRXN2. (467 aa)    
Predicted Functional Partners:
IGSF9
Protein turtle homolog A; Functions in dendrite outgrowth and synapse maturation. Belongs to the immunoglobulin superfamily. Turtle family.
   
 
 0.601
IGSF11
Immunoglobulin superfamily member 11; Functions as a cell adhesion molecule through homophilic interaction. Stimulates cell growth.
  
  
 0.560
NRXN2
Neurexin-2; Neuronal cell surface protein that may be involved in cell recognition and cell adhesion. May mediate intracellular signaling.
   
 
 0.549
KCNH7
Potassium voltage-gated channel subfamily H member 7; Pore-forming (alpha) subunit of voltage-gated potassium channel. Channel properties may be modulated by cAMP and subunit assembly; Belongs to the potassium channel family. H (Eag) (TC 1.A.1.20) subfamily. Kv11.3/KCNH7 sub-subfamily.
   
  
 0.538
IGSF9B
Protein turtle homolog B; Transmembrane protein which is abundantly expressed in interneurons, where it may regulate inhibitory synapse development. May mediate homophilic cell adhesion.
   
 
 0.534
CLVS1
Clavesin-1; Required for normal morphology of late endosomes and/or lysosomes in neurons (By similarity). Binds phosphatidylinositol 3,5- bisphosphate (PtdIns(3,5)P2).
   
 
 0.530
CDH8
Cadherin-8; Cadherins are calcium-dependent cell adhesion proteins. They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types.
   
 
 0.501
CLSTN3
Calsyntenin-3; May modulate calcium-mediated postsynaptic signals. Complex formation with APBA2 and APP, stabilizes APP metabolism and enhances APBA2-mediated suppression of beta-APP40 secretion, due to the retardation of intracellular APP maturation.
   
  
 0.485
LRMDA
Leucine-rich melanocyte differentiation-associated protein; Required for melanocyte differentiation.
    
 
 0.478
KCNA1
Potassium voltage-gated channel subfamily A member 1; Voltage-gated potassium channel that mediates transmembrane potassium transport in excitable membranes, primarily in the brain and the central nervous system, but also in the kidney. Contributes to the regulation of the membrane potential and nerve signaling, and prevents neuronal hyperexcitability. Forms tetrameric potassium-selective channels through which potassium ions pass in accordance with their electrochemical gradient. The channel alternates between opened and closed conformations in response to the voltage difference acros [...]
