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

IZUMO3Izumo sperm-egg fusion protein 3; IZUMO family member 3. (233 aa)    
Predicted Functional Partners:
IZUMO2
Izumo sperm-egg fusion protein 2; IZUMO family member 2.
   
  
 0.848
IZUMO4
Izumo sperm-egg fusion protein 4; IZUMO family member 4; Belongs to the Izumo family.
      
 0.828
IZUMO1
Izumo sperm-egg fusion protein 1; Essential sperm cell-surface protein required for fertilization by acting as a ligand for IZUMO1R/JUNO receptor on egg. The IZUMO1:IZUMO1R/JUNO interaction is a necessary adhesion event between sperm and egg that is required for fertilization but is not sufficient for cell fusion. The ligand- receptor interaction probably does not act as a membrane 'fusogen'.
      
 0.745
CD9
CD9 antigen; Integral membrane protein associated with integrins, which regulates different processes, such as sperm-egg fusion, platelet activation and aggregation, and cell adhesion. Present at the cell surface of oocytes and plays a key role in sperm-egg fusion, possibly by organizing multiprotein complexes and the morphology of the membrane required for the fusion (By similarity). In myoblasts, associates with CD81 and PTGFRN and inhibits myotube fusion during muscle regeneration (By similarity). In macrophages, associates with CD81 and beta-1 and beta-2 integrins, and prevents mac [...]

ADAM2
Disintegrin and metalloproteinase domain-containing protein 2; Sperm surface membrane protein that may be involved in sperm- egg plasma membrane adhesion and fusion during fertilization. Could have a direct role in sperm-zona binding or migration of sperm from the uterus into the oviduct. Interactions with egg membrane could be mediated via binding between its disintegrin-like domain to one or more integrins receptors on the egg. This is a non catalytic metalloprotease-like protein.
   
  
 0.541
CRISP2
Cysteine-rich secretory protein 2; May regulate some ion channels' activity and therebye regulate calcium fluxes during sperm capacitation.
   
  
 0.519
TBPL2
TATA box-binding protein-like protein 2; Transcription factor required in complex with TAF3 for the differentiation of myoblasts into myocytes. The complex replaces TFIID at specific promoters at an early stage in the differentiation process (By similarity); Belongs to the TBP family.
      
 0.517
ACR
Acrosin heavy chain; Acrosin is the major protease of mammalian spermatozoa. It is a serine protease of trypsin-like cleavage specificity, it is synthesized in a zymogen form, proacrosin and stored in the acrosome.
     
 0.514
ACRV1
Acrosomal vesicle protein 1.
   
  
 0.510
CRISP1
Cysteine-rich secretory protein 1; May have a role in sperm-egg fusion and maturation; Belongs to the CRISP family.
