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.

CRISP2Cysteine-rich secretory protein 2; May regulate some ion channels' activity and therebye regulate calcium fluxes during sperm capacitation. (243 aa)    
Predicted Functional Partners:
PGK2
Phosphoglycerate kinase 2; Essential for sperm motility and male fertility. Not required for the completion of spermatogenesis (By similarity); Belongs to the phosphoglycerate kinase family.
   
  
 0.802
GART
Trifunctional purine biosynthetic protein adenosine-3; Phosphoribosylglycinamide formyltransferase, phosphoribosylglycinamide synthetase, phosphoribosylaminoimidazole synthetase; In the central section; belongs to the AIR synthase family.
    
  0.799
MSMB
Beta-microseminoprotein; Microseminoprotein beta.
   
 
 0.729
PLB1
Phospholipase B1, membrane-associated; Membrane-associated phospholipase. Exhibits a calcium- independent broad substrate specificity including phospholipase A2/lysophospholipase activity. Preferential hydrolysis at the sn-2 position of diacylphospholipids and diacyglycerol, whereas it shows no positional specificity toward triacylglycerol. Exhibits also esterase activity toward p-nitrophenyl. May act on the brush border membrane to facilitate the absorption of digested lipids (By similarity).
   
  
 0.665
CRISP3
Cysteine rich secretory protein 3; Belongs to the CRISP family.
  
  
0.661
PATE1
Prostate and testis expressed 1; Belongs to the PATE family.
   
  
 0.658
AKAP4
A-kinase anchor protein 4; Major structural component of sperm fibrous sheath. Plays a role in sperm motility; Belongs to the AKAP110 family.
   
  
 0.654
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'.
   
  
 0.652
C9orf24
Spermatid-specific manchette-related protein 1; May play a role in spermatogenesis (By similarity). May be involved in differentiation or function of ciliated cells. Belongs to the SMRP1 family.
   
  
 0.647
ROPN1L
Ropporin-1-like protein; Important for male fertility. With ROPN1, involved in fibrous sheath integrity and sperm motility, plays a role in PKA-dependent signaling processes required for spermatozoa capacitation.
