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

SPACA1Sperm 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. (294 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 (By similarity).
   
  
 0.835
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'.
   
  
 0.794
DPY19L2
Probable C-mannosyltransferase DPY19L2; Probable C-mannosyltransferase that mediates C-mannosylation of tryptophan residues on target proteins (By similarity). Required during spermatogenesis for sperm head elongation and acrosome formation; Belongs to the dpy-19 family.
      
 0.766
SSMEM1
Serine rich single-pass membrane protein 1.
   
  
 0.714
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.
   
  
 0.706
SPATA16
Spermatogenesis-associated protein 16; Involved in the formation of sperm acrosome, which implicated its potential role in spermatogenesis and sperm-egg fusion.
   
  
 0.688
SPATA46
Spermatogenesis-associated protein 46; Plays a role in spermiogenesis and fertilization.
      
 0.666
SPESP1
Sperm equatorial segment protein 1; Involved in fertilization ability of sperm. Belongs to the SPESP1 family.
      
 0.664
CCDC62
Coiled-coil domain-containing protein 62; Nuclear receptor coactivator that can enhance preferentially estrogen receptors ESR1 and ESR2 transactivation. Modulates also progesterone/PGR, glucocorticoid/NR3C1 and androgen/AR receptors transactivation, although at lower level; little effect on vitamin D receptor/VDR.
   
  
 0.624
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; Belongs to the glycosyl hydrolase 56 family.
