Disease relevance of Mcpt6

  • Tryptase Clara was shown to cleave the hemagglutinin and activate infectivity of influenza A virus in a dose-dependent way [1].
  • Tryptase Clara, an activating protease for Sendai virus in rat lungs, is involved in pneumopathogenicity [2].
  • These results suggest that PAR(2) activation elicited on PTCs by mast cell tryptase contributes to acute testicular inflammation and that this pathogenetic mechanism may also play a role in autoimmune orchitis [3].
  • Trypsin and tryptase, which are agonists for protease-activated receptor-2 (PAR-2), are involved in the pathogenesis of pancreatitis [4].
  • Tryptase Clara activates the infectivity of Sendai and influenza viruses proteolytically [5].

Biological context of Mcpt6

 

Anatomical context of Mcpt6

  • Tryptase Clara is an arginine-specific serine protease localized exclusively in and secreted from Clara cells of the bronchial epithelium of rats (H. Kido, Y. Yokogoshi, K. Sakai, M. Tashiro, Y. Kishino, A. Fukutomi, and N. Katunuma, J. Biol. Chem. 267:13573-13579, 1992) [2].
  • Identification of targeting proteinase for rat alpha 1-macroglobulin in vivo. Mast-cell tryptase is a major component of the alpha 1-macroglobulin-proteinase complex endocytosed into rat liver lysosomes [16].
  • In the progressed stage, tryptase Clara was hard to detect, with heavy accumulation of F2 antigen in the epithelial cells [5].
  • In thin sections embedded in LR White, gold particles indicating immunoreactivity of tryptase Clara were detected specifically in secretory granules of Clara cells [10].
  • On the other hand, AC-17 did significantly blocked the hyperpermeability induced in cultured bovine endothelial cells by tryptase, thrombin and proteinase-activated receptor-2 agonist peptide (SLIGKV-NH(2)) [17].
 

Associations of Mcpt6 with chemical compounds

 

Regulatory relationships of Mcpt6

  • Protease-activated receptor 2 (PAR2) is activated by trypsin and mast cell tryptase to induce widespread inflammation by unknown mechanisms [11].
