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

CST9Cystatin-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. (159 aa)    
Predicted Functional Partners:
CST8
Cystatin-8; Performs a specialized role during sperm development and maturation.
   
  
 0.778
KCMF1
E3 ubiquitin-protein ligase KCMF1; Has intrinsic E3 ubiquitin ligase activity and promotes ubiquitination; Belongs to the KCMF1 family.
    
   0.687
CST9L
Cystatin-9-like; Cystatin 9 like; Belongs to the cystatin family.
   
   
0.661
UBR4
E3 ubiquitin-protein ligase UBR4; E3 ubiquitin-protein ligase which is a component of the N-end rule pathway. Recognizes and binds to proteins bearing specific N- terminal residues that are destabilizing according to the N-end rule, leading to their ubiquitination and subsequent degradation. Together with clathrin, forms meshwork structures involved in membrane morphogenesis and cytoskeletal organization. Regulates integrin- mediated signaling. May play a role in activation of FAK in response to cell-matrix interactions. Mediates ubiquitination of ACLY, leading to its subsequent degrad [...]

CST11
Cystatin-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.
   
  
 0.613
CSTL1
Cystatin like 1.
   
  
 0.600
CST3
Cystatin-C; As an inhibitor of cysteine proteinases, this protein is thought to serve an important physiological role as a local regulator of this enzyme activity; Belongs to the cystatin family.
   
 
 0.563
CST5
Cystatin-D; Cysteine proteinase inhibitor that possibly plays a protective role against proteinases present in the oral cavity. The order of preference for inhibition is cathepsin S > cathepsin H > cathepsin L > cathepsin B.
   
  
 0.538
CST6
Cystatin-M; Shows moderate inhibition of cathepsin B but is not active against cathepsin C; Belongs to the cystatin family.
   
 
 0.536
CST4
Cystatin-S; This protein strongly inhibits papain and ficin, partially inhibits stem bromelain and bovine cathepsin C, but does not inhibit porcine cathepsin B or clostripain. Papain is inhibited non- competitively.
