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

CtseCathepsin E; May have a role in immune function. Probably involved in the processing of antigenic peptides during MHC class II-mediated antigen presentation. May play a role in activation-induced lymphocyte depletion in the thymus, and in neuronal degeneration and glial cell activation in the brain (By similarity). (398 aa)    
Predicted Functional Partners:
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.
   
 
 0.738
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.
   
 
 0.668
Ctsz
Cathepsin Z; Exhibits carboxy-monopeptidase as well as carboxy-dipeptidase activity. Capable of producing kinin potentiating peptides ; Belongs to the peptidase C1 family.
   
 
 0.582
Ctsl
Cathepsin L1 heavy chain; Thiol protease important for the overall degradation of proteins in lysosomes (Probable). Involved in the solubilization of cross-linked TG/thyroglobulin and in the subsequent release of thyroid hormone thyroxine (T4) by limited proteolysis of TG/thyroglobulin in the thyroid follicle lumen (By similarity). Belongs to the peptidase C1 family.
   
 
 0.581
Ctsc
Dipeptidyl peptidase 1 exclusion domain chain; Thiol protease. Has dipeptidylpeptidase activity. Can act as both an exopeptidase and endopeptidase (By similarity).
   
 
 0.570
Cd74
H-2 class II histocompatibility antigen gamma chain; Plays a critical role in MHC class II antigen processing by stabilizing peptide-free class II alpha/beta heterodimers in a complex soon after their synthesis and directing transport of the complex from the endoplasmic reticulum to compartments where peptide loading of class II takes place. Enhance also the stimulation of T-cell responses through interaction with CD44.
   
 0.548
Ctsf
Cathepsin F, isoform CRA_a; Belongs to the peptidase C1 family.
   
 
 0.511
Ctsh
Cathepsin H heavy chain; Important for the overall degradation of proteins in lysosomes; Belongs to the peptidase C1 family.
   
 
 0.497
Ctsa
Carboxypeptidase; Belongs to the peptidase S10 family.
   
 
 0.494
RT1-Db1
Rano class II histocompatibility antigen, D-1 beta chain; Involved in the presentation of foreign antigens to the immune system; Belongs to the MHC class II family.
   
 0.477
