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

CyssCystatin-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. (141 aa)    
Predicted Functional Partners:
Grpca
Submandibular gland secretory Glx-rich protein CB; GRP proteins have a marked affinity for hydroxyapatite. They may play a role in the formation of the protective acquired pellicle at the saliva-tooth interface.
   
  
 0.664
Prpmp5
Proline-rich protein MP5.
      
 0.662
Cstb
Cystatin-B; This is an intracellular thiol proteinase inhibitor; Belongs to the cystatin family.
   
 
 0.613
Vegp2
Von Ebner gland protein 2; Could play a role in taste reception. Could be necessary for the concentration and delivery of sapid molecules in the gustatory system.
   
  
 0.613
Ctsb
Cathepsin B heavy chain; Thiol protease which is believed to participate in intracellular degradation and turnover of proteins. Cleaves matrix extracellular phosphoglycoprotein MEPE (By similarity). Involved in the solubilization of cross-linked TG/thyroglobulin in the thyroid follicle lumen (By similarity). Has also been implicated in tumor invasion and metastasis (By similarity). Belongs to the peptidase C1 family.
   
 
 0.608
Ctss
Cathepsin S; Thiol protease. Key protease responsible for the removal of the invariant chain from MHC class II molecules. The bond-specificity of this proteinase is in part similar to the specificities of cathepsin L (By similarity). May be involved in thyroid hormone biosynthesis. Belongs to the peptidase C1 family.
   
 
 0.588
RGD1306750
Gliadoralin-A; May play a role in the formation of the protective mucosal protein pellicle involved in the reinforcement and protection of oral mucosal epithelial surface.
      
 0.581
Prb3
Proline-rich protein BstNI subfamily 3.
   
  
 0.566
Lgmn
Legumain; Has a strict specificity for hydrolysis of asparaginyl bonds. Can also cleave aspartyl bonds slowly, especially under acidic conditions. Required for normal lysosomal protein degradation in renal proximal tubules. Required for normal degradation of internalized EGFR. Plays a role in the regulation of cell proliferation via its role in EGFR degradation. May be involved in the processing of proteins for MHC class II antigen presentation in the lysosomal/endosomal system (By similarity); Belongs to the peptidase C13 family.
    
 
 0.540
Cst9l
Cystatin 9 (Predicted).
