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-1A; 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. Belongs to the ropporin family. (212 aa)    
Predicted Functional Partners:
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.
   
 
 0.989
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.
    
 0.987
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).
    
 
 0.975
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. Isoform 1 binds calcium in vitro. Isoform 2 and isoform 6 probably bind calcium. Isoform 3 and isoform 5 do not bind calcium in vitro. Isoform 4 probably does not bind calcium.
   
  
 0.953
ROPN1B
Ropporin-1B; 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. Belongs to the ropporin family.
  
 
0.884
AKAP4
A-kinase anchor protein 4; Major structural component of sperm fibrous sheath. Plays a role in sperm motility; Belongs to the AKAP110 family.
   
 
 0.660
AKAP1
A-kinase anchor protein 1, mitochondrial; Binds to type I and II regulatory subunits of protein kinase A and anchors them to the cytoplasmic face of the mitochondrial outer membrane.
      
 0.635
TEKT4
Tektin-4; May be a structural component of the sperm flagellum. Contributes to normal sperm motility; Belongs to the tektin family.
   
  
 0.622
PRKAR2B
cAMP-dependent protein kinase type II-beta regulatory subunit; Regulatory subunit of the cAMP-dependent protein kinases involved in cAMP signaling in cells. Type II regulatory chains mediate membrane association by binding to anchoring proteins, including the MAP2 kinase.
    
 
 0.615
TSSK4
Testis-specific serine/threonine-protein kinase 4; Serine/threonine kinase which is involved in male germ cell development and in mature sperm function (By similarity). May be involved in the Cre/Creb signaling pathway (By similarity). Phosphorylates CREB1 on 'Ser-133' in vitro and can stimulate Cre/Creb pathway in cells. Phosphorylates CREM on 'Ser-116' in vitro (By similarity). Phosphorylates ODF2 on 'Ser-95' (By similarity). Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family.
