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

CTSKCathepsin K; Thiol protease involved in osteoclastic bone resorption and may participate partially in the disorder of bone remodeling. Displays potent endoprotease activity against fibrinogen at acid pH. May play an important role in extracellular matrix degradation. Involved in the release of thyroid hormone thyroxine (T4) by limited proteolysis of TG/thyroglobulin in the thyroid follicle lumen. (329 aa)    
Predicted Functional Partners:
BCL2
Apoptosis regulator Bcl-2; Suppresses apoptosis in a variety of cell systems including factor-dependent lymphohematopoietic and neural cells. Regulates cell death by controlling the mitochondrial membrane permeability. Appears to function in a feedback loop system with caspases. Inhibits caspase activity either by preventing the release of cytochrome c from the mitochondria and/or by binding to the apoptosis-activating factor (APAF-1) (By similarity). May attenuate inflammation by impairing NLRP1-inflammasome activation, hence CASP1 activation and IL1B release (By similarity).
   
 
 0.931
NFATC1
Nuclear factor of activated T-cells, cytoplasmic 1; Plays a role in the inducible expression of cytokine genes in T-cells, especially in the induction of the IL-2 or IL-4 gene transcription. Also controls gene expression in embryonic cardiac cells. Could regulate not only the activation and proliferation but also the differentiation and programmed death of T-lymphocytes as well as lymphoid and non-lymphoid cells. Required for osteoclastogenesis and regulates many genes important for osteoclast differentiation and function (By similarity).
   
  
 0.919
SERPINB13
Serpin family B member 13; Belongs to the serpin family.
    
 0.913
BID
BH3-interacting domain death agonist; Counters the protective effect of Bcl-2.
   
 
 0.913
BCL2L1
BCL2-like 1 transcript variant 1.
     
 0.908
DCSTAMP
Dendrocyte expressed seven transmembrane protein.
      
 0.890
CALCR
Calcitonin receptor; Belongs to the G-protein coupled receptor 2 family.
      
 0.889
ATP6V0D2
V-type proton ATPase subunit d 2; Subunit of the integral membrane V0 complex of vacuolar ATPase. Vacuolar ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells, thus providing most of the energy required for transport processes in the vacuolar system. May play a role in coupling of proton transport and ATP hydrolysis (By similarity); Belongs to the V-ATPase V0D/AC39 subunit family.
      
 0.878
MMP9
Matrix metalloproteinase-9; Could play a role in bone osteoclastic resorption. Cleaves type IV and type V collagen into large C-terminal three quarter fragments and shorter N-terminal one quarter fragments (By similarity). Belongs to the peptidase M10A family.
   
 
 0.835
OCSTAMP
Osteoclast stimulatory transmembrane protein.
      
 0.822
