+== Function ==
+[https://www.uniprot.org/uniprot/TRYB1_HUMAN TRYB1_HUMAN] Tryptase is the major neutral protease present in mast cells and is secreted upon the coupled activation-degranulation response of this cell type (By similarity).
+<div style="background-color:#fffaf0;">
+== Publication Abstract from PubMed ==
+Tryptase, a serine protease released from mast cells, is implicated in many allergic and inflammatory disorders. Human tryptase is a donut-shaped tetramer with the active sites facing inward forming a central pore. Bivalent ligands spanning two active sites potently inhibit this configuration, but these large compounds have poor drug-like properties. To overcome some of these challenges, we developed self-assembling molecules, called coferons, which deliver a larger compound in two parts. Using a pharmacophoric core and reversibly binding linkers to span two active sites, we have successfully produced three novel homodimeric tryptase inhibitors. Upon binding to tryptase, compounds reassembled into flexible homodimers, with significant improvements in IC(50) (0.19 +/- 0.08 muM) over controls (5.50 +/- 0.09 muM), and demonstrate good activity in mast cell lines. These studies provide validation for this innovative technology that is especially well-suited for the delivery of dimeric drugs to modulate intracellular macromolecular targets.
