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.

SPEM1Spermatid maturation protein 1; Required for proper cytoplasm removal during spermatogenesis. (309 aa)    
Predicted Functional Partners:
TNP1
Spermatid nuclear transition protein 1; Plays a key role in the replacement of histones to protamine in the elongating spermatids of mammals. In condensing spermatids, loaded onto the nucleosomes, where it promotes the recruitment and processing of protamines, which are responsible for histone eviction. Belongs to the nuclear transition protein 1 family.
   
  
 0.750
FAM166A
Protein FAM166A; Family with sequence similarity 166 member A.
   
    0.730
TMEM190
Transmembrane protein 190.
   
  
 0.694
FAM209A
Protein FAM209A; Family with sequence similarity 209 member A.
   
  
 0.685
PRM2
Basic nuclear protein HPI1; Protamines substitute for histones in the chromatin of sperm during the haploid phase of spermatogenesis. They compact sperm DNA into a highly condensed, stable and inactive complex.
   
  
 0.678
SPATA16
Spermatogenesis-associated protein 16; Involved in the formation of sperm acrosome, which implicated its potential role in spermatogenesis and sperm-egg fusion.
   
  
 0.638
SPATA3
Spermatogenesis-associated protein 3; Spermatogenesis associated 3.
   
  
 0.637
ARRDC5
Arrestin domain containing 5; Belongs to the arrestin family.
   
  
 0.635
TNP2
Nuclear transition protein 2; Plays a key role in the replacement of histones to protamine in the elongating spermatids of mammals. In condensing spermatids, loaded onto the nucleosomes, where it promotes the recruitment and processing of protamines, which are responsible for histone eviction.
   
  
 0.626
PPP1R1A
Protein phosphatase 1 regulatory subunit 1A; Inhibitor of protein-phosphatase 1. This protein may be important in hormonal control of glycogen metabolism. Hormones that elevate intracellular cAMP increase I-1 activity in many tissues. I-1 activation may impose cAMP control over proteins that are not directly phosphorylated by PKA. Following a rise in intracellular calcium, I-1 is inactivated by calcineurin (or PP2B). Does not inhibit type-2 phosphatases.
