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

Prss21Testisin; Could regulate proteolytic events associated with testicular germ cell maturation; Belongs to the peptidase S1 family. (324 aa)    
Predicted Functional Partners:
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.

Oaz3
Ornithine decarboxylase antizyme 3; Ornithine decarboxylase (ODC) antizyme protein that negatively regulates ODC activity and intracellular polyamine biosynthesis and uptake in response to increased intracellular polyamine levels. Binds to ODC monomers, inhibiting the assembly of the functional ODC homodimers. Does not target the ODC monomers for degradation, which allows a protein synthesis-independent restoration of ODC activity. Stabilizes AZIN2 by interfering with its ubiquitination. Involved in the translocation of AZNI2 from ER-Golgi intermediate compartment (ERGIC) to the cytoso [...]

Spint1
Kunitz-type protease inhibitor 1; Inhibitor of HGF activator.
   
 
 0.526
Prss37
Probable inactive serine protease 37; Plays a role in male fertility. May have a role in sperm migration or binding to zona-intact eggs. Involved in the activation of the proacrosin/acrosin system (By similarity).
   
  
 0.522
Spint2
Kunitz-type protease inhibitor 2; Inhibitor of HGF activator.
   
 
 0.504
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.
   
 
 0.489
Adam3
A disintegrin and metallopeptidase domain 3; Involved in fertilization by controlling sperm migration into oviduct.
   
  
 0.475
Spatc1l
Speriolin-like protein; Belongs to the speriolin family.
   
  
 0.460
Glipr1l1
GLIPR1-like protein 1; Plays a role in the binding between sperm and oocytes. Component of epididymosomes, one type of membranous microvesicules which mediate the transfer of lipids and proteins to spermatozoa plasma membrane during epididymal maturation. Also component of the CD9-positive microvesicules found in the cauda region.
   
  
 0.457
Ccdc42
Coiled-coil domain-containing protein 42; Required for sperm development. Belongs to the CFAP73 family.
   
  
 0.450
