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

Ropn1Ropporin-1; Important for male fertility. With ROPN1L, involved in fibrous sheath integrity and sperm motility, plays a role in PKA- dependent signaling processes required for spermatozoa capacitation. (212 aa)    
Predicted Functional Partners:
Rhpn1
Rhophilin-1; Has no enzymatic activity. May serve as a target for Rho, and interact with some cytoskeletal component upon Rho binding or relay a Rho signal to other molecules; Belongs to the RHPN family.
    
 0.923
Akap3
A-kinase anchor protein 3; May function as a regulator of both motility- and head- associated functions such as capacitation and the acrosome reaction. Belongs to the AKAP110 family.
   
 
 0.832
Spa17
Sperm surface protein Sp17; Sperm surface zona pellucida binding protein. Helps to bind spermatozoa to the zona pellucida with high affinity. Might function in binding zona pellucida and carbohydrates (By similarity).
   
 
 0.784
Cabyr
Calcium-binding tyrosine phosphorylation-regulated protein; May function as a regulator of both motility- and head- associated functions such as capacitation and the acrosome reaction. May bind calcium in vitro (By similarity).
   
 
 0.753
Akap4
A-kinase anchor protein 4; Major structural component of sperm fibrous sheath. Plays a role in sperm motility.
   
 
 0.729
Fscb
Fibrous sheath CABYR-binding protein; May be involved in the later stages of fibrous sheath biogenesis and spermatozoa capacitation. Inhibits ROPN1 and ROPN1L SUMOylation. Binds calcium.
   
  
 0.687
Zpbp
Zona pellucida-binding protein 1; Plays a role in acrosome compaction and sperm morphogenesis. Is implicated in sperm-oocyte interaction during fertilization. Belongs to the zona pellucida-binding protein Sp38 family.
   
  
 0.662
Fsip2
Fibrous sheath-interacting protein 2; Plays a role in spermatogenesis.
   
  
 0.628
Meig1
Meiosis-expressed gene 1 protein; Essential for spermiogenesis; Belongs to the MEIG1 family.
   
  
 0.626
Tekt4
Tektin-4; May be a structural component of the sperm flagellum. Contributes to normal sperm motility.
   
  
 0.604
