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.

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. (215 aa)    
Predicted Functional Partners:
AADAT
Kynurenine/alpha-aminoadipate aminotransferase, mitochondrial; Transaminase with broad substrate specificity. Has transaminase activity towards aminoadipate, kynurenine, methionine and glutamate. Shows activity also towards tryptophan, aspartate and hydroxykynurenine. Accepts a variety of oxo-acids as amino-group acceptors, with a preference for 2-oxoglutarate, 2-oxocaproic acid, phenylpyruvate and alpha-oxo-gamma-methiol butyric acid. Can also use glyoxylate as amino-group acceptor (in vitro). Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family.

LYZL4
Lysozyme-like protein 4; May be involved in fertilization (By similarity). Has no detectable bacteriolytic and lysozyme activities in vitro (By similarity); Belongs to the glycosyl hydrolase 22 family.

SPACA4
Sperm acrosome membrane-associated protein 4; Sperm surface membrane protein that may be involved in sperm- egg plasma membrane adhesion and fusion during fertilization.
   
  
 0.703
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).
   
  
 0.695
ACRBP
Acrosin-binding protein; May be involved in packaging and condensation of the acrosin zymogen in the acrosomal matrix via its association with proacrosin.
   
  
 0.667
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.
   
  
 0.650
TMEM190
Transmembrane protein 190.
   
  
 0.649
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'.

SPACA9
Sperm acrosome associated 9.

HSPB3
Heat shock protein beta-3; Inhibitor of actin polymerization.
