Subcellular location

Subcellular Location:
Secreted. Note=Released from the secretory granules upon mast cell activation.

Function

Function:
Tryptase is the major neutral protease present in mast cells and is secreted upon the coupled activation-degranulation response of this cell type. May play a role in innate immunity.
Catalytic Activity:
Preferential cleavage: Arg-|-Xaa, Lys-|-Xaa, but with more restricted specificity than trypsin.
Active Site:
ACT_SITE 74 74 Charge relay system.; ACT_SITE 121 121 Charge relay system.; ACT_SITE 224 224 Charge relay system.
