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

TPPP2Tubulin polymerization-promoting protein family member 2; Probable regulator of microtubule dynamics required for sperm motility (Probable). In contrast to other members of the family, has no microtubule bundling activity. (170 aa)    
Predicted Functional Partners:
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 cytos [...]

SPACA1
Sperm acrosome membrane-associated protein 1; Plays a role in acrosome expansion and establishment of normal sperm morphology during spermatogenesis (By similarity). Important for male fertility.
   
  
 0.535
ZPBP
Zona pellucida-binding protein 1; Plays a role in acrosome compaction and sperm morphogenesis. Is implicated in sperm-oocyte interaction during fertilization (By similarity).
   
  
 0.531
PRSS55
Serine protease 55; Probable serine protease.
   
  
 0.519
TMPRSS12
Transmembrane serine protease 12; Belongs to the peptidase S1 family.
   
  
 0.507
RSPH1
Radial spoke head 1 homolog; May play an important role in male meiosis (By similarity). It is necessary for proper building of the axonemal central pair and radial spokes.
      
 0.483
NTN3
Netrin-3; Netrins control guidance of CNS commissural axons and peripheral motor axons.
   
  
 0.428
FAM71E1
Protein FAM71E1; Family with sequence similarity 71 member E1.
   
  
 0.425
HSPB9
Heat shock protein family B member 9.
   
  
 0.417
NME8
Thioredoxin domain-containing protein 3; Probably required during the final stages of sperm tail maturation in the testis and/or epididymis, where extensive disulfide bonding of fibrous sheath (FS) proteins occurs. May be involved in the reduction of disulfide bonds within the sperm FS components. In vitro, it has neither NDP kinase nor reducing activity on disulfide bonds.
