== Function ==
[https://www.uniprot.org/uniprot/TRYB2_HUMAN TRYB2_HUMAN] Tryptase is the major neutral protease present in mast cells and is secreted upon the coupled activation-degranulation response of this cell type. Has an immunoprotective role during bacterial infection. Required to efficiently combat K.pneumoniae infection (By similarity).

== Publication Abstract from PubMed ==
Tryptase is a serine protease found almost exclusively in mast cells. It has trypsin-like specificity, favoring cleavage of substrates with an arginine (or lysine) at the P1 position, and has optimal catalytic activity at neutral pH. Current evidence suggests tryptase beta is the most important form released during mast cell activation in allergic diseases. It is shown to have numerous pro-inflammatory cellular activities in vitro, and in animal models tryptase provokes broncho-constriction and induces a cellular inflammatory infiltrate characteristic of human asthma. Screening of in-house inhibitors of factor Xa (a closely related serine protease) identified beta-amidoester benzamidines as potent inhibitors of recombinant human betaII tryptase. X-ray structure driven template modification and exchange of the benzamidine to optimize potency and pharmacokinetic properties gave selective, potent and orally bioavailable 4-(3-aminomethyl phenyl)piperidinyl-1-amides.
