"FOLR4" - Sperm-egg fusion protein Juno 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

FOLR4Sperm-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)    
Predicted Functional Partners:
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’ (350 aa)
       
 
  0.977
LY6K
Lymphocyte antigen 6K; Required for sperm migration into the oviduct and male fertility by controlling binding of sperm to zona pellucida (By similarity). May play a role in cell growth; LY6/PLAUR domain containing (165 aa)
         
  0.936
CPM
Carboxypeptidase M; Specifically removes C-terminal basic residues (Arg or Lys) from peptides and proteins. It is believed to play important roles in the control of peptide hormone and growth factor activity at the cell surface, and in the membrane-localized degradation of extracellular proteins; Belongs to the peptidase M14 family (443 aa)
         
  0.918
MSLN
Mesothelin; Membrane-anchored forms may play a role in cellular adhesion (630 aa)
         
  0.916
CD52
CAMPATH-1 antigen; May play a role in carrying and orienting carbohydrate, as well as having a more specific role; CD molecules (61 aa)
         
  0.910
PRND
Prion-like protein doppel; Required for normal acrosome reaction and for normal male fertility (By similarity). Can bind Cu(2+); Belongs to the prion family (176 aa)
         
  0.906
CD109
CD109 antigen; Modulates negatively TGFB1 signaling in keratinocytes; Belongs to the protease inhibitor I39 (alpha-2- macroglobulin) family (1445 aa)
         
  0.903
FOLR2
Folate receptor beta; Binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate and folate analogs into the interior of cells. Has high affinity for folate and folic acid analogs at neutral pH. Exposure to slightly acidic pH after receptor endocytosis triggers a conformation change that strongly reduces its affinity for folates and mediates their release (255 aa)
         
0.902
NRN1
Neuritin; Promotes neurite outgrowth and especially branching of neuritic processes in primary hippocampal and cortical cells (168 aa)
     
 
    0.902
NRN1L
Neuritin-like protein; Neuritin 1 like (165 aa)
