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

Spesp1Sperm equatorial segment protein 1; Involved in fertilization ability of sperm. (399 aa)    
Predicted Functional Partners:
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.
   
  
 0.679
Spaca3
Sperm 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.
   
  
 0.654
Zan
Zonadhesin; Binds in a species-specific manner to the zona pellucida of the egg. May be involved in gamete recognition and/or signaling.
   
  
 0.648
Spam1
Hyaluronidase PH-20; Involved in sperm-egg adhesion. Upon fertilization sperm must first penetrate a layer of cumulus cells that surrounds the egg before reaching the zona pellucida. The cumulus cells are embedded in a matrix containing hyaluronic acid which is formed prior to ovulation. This protein aids in penetrating the layer of cumulus cells by digesting hyaluronic acid.
   
  
 0.645
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.
      
 0.642
Odf1
Outer dense fiber protein 1; Component of the outer dense fibers (ODF) of spermatozoa. ODF are filamentous structures located on the outside of the axoneme in the midpiece and principal piece of the mammalian sperm tail and may help to maintain the passive elastic structures and elastic recoil of the sperm tail.
   
  
 0.642
Smcp
Sperm mitochondrial-associated cysteine-rich protein; Involved in sperm motility. Its absence is associated with genetic background dependent male infertility. Infertility may be due to reduced sperm motility in the female reproductive tract and inability to penetrate the oocyte zona pellucida.
   
  
 0.604
Zp1
Processed zona pellucida sperm-binding protein 1; 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. ZP1 ensures the structural integrity of the zona pellucida.
   
  
 0.574
4930451I11Rik
RIKEN cDNA 4930451I11 gene.
   
  
 0.572
Acrv1
Acrosomal protein SP-10.
   
  
 0.549
