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

IZUMO2Izumo sperm-egg fusion protein 2; IZUMO family member 2. (221 aa)    
Predicted Functional Partners:
IZUMO3
Izumo sperm-egg fusion protein 3; IZUMO family member 3.
   
  
 0.848
IZUMO4
Izumo sperm-egg fusion protein 4; IZUMO family member 4; Belongs to the Izumo family.
      
 0.824
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'.

ISOC2
Isochorismatase domain containing 2.
      
 0.573
ADAM32
Disintegrin and metalloproteinase domain-containing protein 32; May play a role in sperm development and fertilization This is a non-catalytic metalloprotease-like protein.
   
  
 0.572
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 [...]

C2orf83
Folate transporter-like protein C2orf83; Chromosome 2 open reading frame 83.
   
    0.530
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.
      
 0.528
OR4N5
Olfactory receptor 4N5; Odorant receptor; Belongs to the G-protein coupled receptor 1 family.
      
 0.525
SPACA4
Sperm acrosome membrane-associated protein 4; Sperm surface membrane protein that may be involved in sperm- egg plasma membrane adhesion and fusion during fertilization.
