Associations of Prss1 with chemical compounds

  • (a) Calcium and pancreatic trypsin inhibitor completely inhibit the binding at concentrations when the degradation is not altered; (b) the sequences of peptides of ACTH which inhibit the binding and degradation of 125-I-ACTH-1-24 are different [18].
  • All three proteases were found to belong to the family of chymotrypic serine proteases as deduced from the absence of the Asp 189 which is characteristic for all serine proteases having cleavage specificities similar to pancreatic trypsin [19].
  • The most effective inhibitors were N-ethylmaleimide, bacitracin, and Kunitz pancreatic trypsin inhibitor [20].
  • Cholesterol sulfate and I3SO3-GalCer, which were commonly contained in the epithelia of mammalian digestive tracts, were found to inhibit the activities of typical digestive enzymes, pancreatic trypsin and chymotrypsin, but steroid sulfates, gangliosides and the other membrane constituents did not show any inhibitory activity [17].
  • By day 21, rats treated with octreotide in the camostate group showed a reduced basal pancreatic trypsin concentration and a decreased basal trypsin content (although the changes were not significant) [21].

Regulatory relationships of Prss1

  • Conclusion: Exogenous and endogenous CCK seem not to influence milk intake while decrease pancreatic trypsin/protein ratio [12].

Other interactions of Prss1


Analytical, diagnostic and therapeutic context of Prss1

  • The stability of the mRNAs encoding pancreatic trypsin isozymes, namely the cationic form and the two anionic forms I and II, as well as that of the secretory trypsin inhibitors I and II, were studied in rats fed on either a high-protein diet, or a protein-free diet compared with a standard diet for a 10-day period [25].
