STRING protein interaction network
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:
some 3D structure is known or predicted
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
CST11Cystatin-11; Has antibacterial activity against the Gram-negative bacteria E.coli. May play a role in sperm maturation and fertilization; Belongs to the cystatin family (138 aa)    
Predicted Functional Partners:
NTF2-related export protein 1; Stimulator of protein export for NES-containing proteins. Also plays a role in the nuclear export of U1 snRNA, tRNA, and mRNA. The NXF1-NXT1 heterodimer is involved in the export of HSP70 mRNA in conjunction with ALYREF/THOC4 and THOC5
Epididymal-specific lipocalin-9; Lipocalin 9; Lipocalins
Epididymal-specific lipocalin-8; May play a role in male fertility. May act as a retinoid carrier protein within the epididymis; Lipocalins
Cystatin-F; Inhibits papain and cathepsin L but with affinities lower than other cystatins. May play a role in immune regulation through inhibition of a unique target in the hematopoietic system; Cystatins, type 2
Acetyl-coenzyme A synthetase 2-like, mitochondrial; Important for maintaining normal body temperature during fasting and for energy homeostasis. Essential for energy expenditure under ketogenic conditions (By similarity). Converts acetate to acetyl-CoA so that it can be used for oxidation through the tricarboxylic cycle to produce ATP and CO(2); Belongs to the ATP-dependent AMP-binding enzyme family
GDNF-inducible zinc finger protein 1; Transcriptional repressor. Binds the GZF1 responsive element (GRE) (consensus: 5'-TGCGCN[TG][CA]TATA-3'). May be regulating VSX2/HOX10 expression; Belongs to the krueppel C2H2-type zinc-finger protein family
Cystatin-9; May be involved in testis development (By similarity). May play a role in hematopoietic differentiation or inflammation. Has immunomodulatory and antimicrobial functions against Francisella tularensis, a Gram-negative bacteria; Belongs to the cystatin family
Disintegrin and metalloproteinase domain-containing protein 7; May play an important role in male reproduction including sperm maturation and gonadotrope function. This is a non catalytic metalloprotease-like protein (By similarity); ADAM metallopeptidase domain containing
Inactive ribonuclease-like protein 10; Secreted proximal epididymal protein required for post- testicular sperm maturation and male fertility. May be involved in sperm adhesion to the egg zona pellucida. Does not have ribonuclease activity (By similarity)
Tropomyosin alpha-3 chain; Binds to actin filaments in muscle and non-muscle cells. Plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction. Smooth muscle contraction is regulated by interaction with caldesmon. In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments; Belongs to the tropomyosin family
