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

SPAG8Sperm-associated antigen 8; Plays a role in spermatogenesis by enhancing the binding of CREM isoform tau to its coactivator FHL5 and increasing the FHL5- regulated transcriptional activation of CREM isoform tau (By similarity). Involved in the acrosome reaction and in binding of sperm to the zona pellucida (By similarity). Plays a role in regulation of the cell cycle by controlling progression through the G2/M phase, possibly by delaying the activation of CDK1 which is required for entry into mitosis. May play a role in fertility and microtubule formation through interaction with RANBP9. (501 aa)    
Predicted Functional Partners:
TEKT3
Tektin-3; May be a structural component of the sperm flagellum. Required for normal sperm mobility.
   
   0.913
CFAP126
Protein Flattop; Acts as a regulator of cilium basal body docking and positioning in mono- and multiciliated cells. Regulates basal body docking and cilia formation in multiciliated lung cells. Regulates kinocilium positioning and stereocilia bundle morphogenesis in the inner ear.
   
 
 0.908
CFAP53
Cilia- and flagella-associated protein 53; May play a role in the beating of primary cilia and thereby be involved in the establishment of organ laterality during embryogenesis.
   
   0.859
CFAP52
Cilia- and flagella-associated protein 52; May play a role in cell growth and/or survival. Belongs to the CFAP52 family.
   
   0.845
PACRG
Parkin coregulated gene protein; Suppresses cell death induced by accumulation of unfolded Pael receptor (Pael-R, a substrate of Parkin). Facilitates the formation of inclusions consisting of Pael-R, molecular chaperones, protein degradation molecules and itself when proteasome is inhibited. May play an important role in the formation of Lewy bodies and protection of dopaminergic neurons against Parkinson disease.
   
 
 0.842
TEKT2
Tektin-2; Structural component of ciliary and flagellar microtubules. Plays a key role in the assembly or attachment of the inner dynein arm to microtubules in sperm flagella and tracheal cilia. Forms filamentous polymers in the walls of ciliary and flagellar microtubules.
   
   0.838
EFHC2
EF-hand domain-containing family member C2; EF-hand domain containing 2.
   
   0.838
EFHC1
EF-hand domain-containing protein 1; Microtubule-associated protein which regulates cell division and neuronal migration during cortical development. Necessary for mitotic spindle organization. Necessary for radial and tangential cell migration during brain development, possibly acting as a regulator of cell morphology and process formation during migration. May enhance calcium influx through CACNA1E and stimulate programmed cell death.
   
   0.835
TEKT1
Tektin-1; Structural component of ciliary and flagellar microtubules. Forms filamentous polymers in the walls of ciliary and flagellar microtubules; Belongs to the tektin family.
   
   0.834
TEKT4
Tektin-4; May be a structural component of the sperm flagellum. Contributes to normal sperm motility; Belongs to the tektin family.
