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

Spaca3Sperm acrosome membrane-associated protein 3, processed form; Sperm surface membrane protein that may be involved in sperm- egg plasma membrane adhesion and fusion during fertilization. It could be a potential receptor for the egg oligosaccharide residue N- acetylglucosamine, which is present in the extracellular matrix over the egg plasma membrane. The processed form has no detectable bacteriolytic activity in vitro (By similarity); Belongs to the glycosyl hydrolase 22 family. (163 aa)    
Predicted Functional Partners:
Tmem190
Transmembrane protein 190.
   
  
 0.821
Spaca1
Sperm acrosome membrane-associated protein 1; Plays a role in acrosome expansion and establishment of normal sperm morphology during spermatogenesis. Important for male fertility.
   
  
 0.734
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'.
   
  
 0.694
Spesp1
Sperm equatorial segment protein 1; Involved in fertilization ability of sperm.
   
  
 0.654
Zpbp
Zona pellucida-binding protein 1; Plays a role in acrosome compaction and sperm morphogenesis. Is implicated in sperm-oocyte interaction during fertilization. Belongs to the zona pellucida-binding protein Sp38 family.
   
  
 0.626
Zpbp2
Zona pellucida-binding protein 2; Is implicated in sperm-oocyte interaction during fertilization.
   
  
 0.599
Astl
Astacin-like metalloendopeptidase; Oocyte-specific oolemmal receptor involved in sperm and egg adhesion and fertilization. Plays a role in the polyspermy inhibition. Probably acts as a protease for the post-fertilization cleavage of ZP2. Cleaves the sperm-binding ZP2 at the surface of the zona pellucida after fertilization and cortical granule exocytosis, rendering the zona pellucida unable to support further sperm binding.
   
  
 0.563
Acrv1
Acrosomal protein SP-10.
   
 
 0.562
Izumo4
Izumo sperm-egg fusion protein 4.
      
 0.525
Prm2
Protamine-2; Protamines substitute for histones in the chromatin of sperm during the haploid phase of spermatogenesis. They compact sperm DNA into a highly condensed, stable and inactive complex.
