"IZUMO1" - Izumo sperm-egg fusion protein 1 in Homo sapiens
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

IZUMO1Izumo 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’ (350 aa)    
Predicted Functional Partners:
FOLR4
Sperm-egg fusion protein Juno; Receptor for IZUMO1 present at the cell surface of oocytes (oolemma), which is essential for species-specific gamete recognition and fertilization. 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’. Does not bind folate (195 aa)
       
 
  0.977
CD9
CD9 antigen; Involved in platelet activation and aggregation. Regulates paranodal junction formation. Involved in cell adhesion, cell motility and tumor metastasis. Required for sperm-egg fusion; Belongs to the tetraspanin (TM4SF) family (228 aa)
         
  0.966
IZUMO3
Izumo sperm-egg fusion protein 3; IZUMO family member 3 (233 aa)
     
   
  0.726
IZUMO4
Izumo sperm-egg fusion protein 4; IZUMO family member 4; Belongs to the Izumo family (232 aa)
           
  0.707
CLGN
Calmegin; Functions during spermatogenesis as a chaperone for a range of client proteins that are important for sperm adhesion onto the egg zona pellucida and for subsequent penetration of the zona pellucida. Required for normal sperm migration from the uterus into the oviduct. Required for normal male fertility. Binds calcium ions (By similarity) (610 aa)
           
  0.684
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; ADAM metallopeptidase domain containing (735 aa)
     
   
  0.668
IZUMO2
Izumo sperm-egg fusion protein 2; IZUMO family member 2 (221 aa)
     
   
  0.663
GPR15
G-protein coupled receptor 15; Probable chemokine receptor. Alternative coreceptor with CD4 for HIV-1 infection; G protein-coupled receptors, Class A orphans (360 aa)
           
  0.649
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; LY6/PLAUR domain containing (124 aa)
           
  0.648
TSSK6
Testis-specific serine/threonine-protein kinase 6; Required for sperm production and function. Plays a role in DNA condensation during postmeiotic chromatin remodeling (By similarity) (273 aa)
