Area of Science:

  • Biochemistry
  • Molecular Biology
  • Physiology

Context:

  • Protease-activated receptors (PARs) are a family of G-protein-coupled receptors.
  • PAR-2 is activated by proteases like trypsin and coagulation factors.
  • PAR-2 exhibits diverse tissue distribution and functions.

Purpose:

  • To summarize the physiological roles of PAR-2.
  • To highlight PAR-2's involvement in various body systems.
  • To underscore PAR-2's significance as a drug development target.

Summary:

  • PAR-2 plays critical roles in the gastrointestinal tract, circulatory system, respiratory system, and nervous system.
  • In the gut, it influences cytoprotection, motility, and secretion.
  • In circulation, PAR-2 activation leads to vasodilation and hypotension.
