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.

PKDREJPolycystic kidney disease and receptor for egg jelly-related protein; May have a central role in fertilization. May generate a Ca(2+) transporting channel directly involved in initiating the acrosome reaction of the sperm; Belongs to the polycystin family. (2253 aa)    
Predicted Functional Partners:
ZP3
Processed zona pellucida sperm-binding protein 3; Component of the zona pellucida, an extracellular matrix surrounding oocytes which mediates sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy. The zona pellucida is composed of 3 to 4 glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP3 is essential for sperm binding and zona matrix formation.

CDPF1
Cysteine rich DPF motif domain containing 1.
 
    
 0.592
ZAN
Zonadhesin; Binds in a species-specific manner to the zona pellucida of the egg. May be involved in gamete recognition and/or signaling.

C9orf43
Uncharacterized protein C9orf43; Chromosome 9 open reading frame 43.
      
 0.569
ZFAND4
Zinc finger AN1-type containing 4.
   
 
 0.568
PKD1L3
Polycystic kidney disease protein 1-like 3; Component of a calcium channel. May act as a sour taste receptor by forming a calcium channel with PKD1L3 in gustatory cells; however, its contribution to sour taste perception is unclear in vivo and may be indirect.
  
 
0.549
C12orf40
Uncharacterized protein C12orf40; Chromosome 12 open reading frame 40.
      
 0.542
C9orf131
Uncharacterized protein C9orf131; Chromosome 9 open reading frame 131.
    
 
 0.537
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'.
      
 0.530
SPATA16
Spermatogenesis-associated protein 16; Involved in the formation of sperm acrosome, which implicated its potential role in spermatogenesis and sperm-egg fusion.
