| Function
Tryptase (TRP) is a serine protease found in mast cells[1].
Relevance
TRP is used as a marker for mast cell activation[2]. Inhibitors of TRP have therapeutic potential for treating allergic or inflammatory disorders such as asthma and inflammatory bowel diseases[3].
Structural highlights
The biological assembly of Human tryptase is homotetramer (2zeb). The piperidine derivative TRP inhibitor interacts with both subunits of TRP[4]. Water molecules are shown as red spheres.
