Immunol. 169:5145-5152(2002). CC -!- FUNCTION: Tryptase is the major neutral protease present in mast CC cells and is secreted upon the coupled activation-degranulation CC response of this cell type (By similarity). CC -!- CATALYTIC ACTIVITY: Preferential cleavage: Arg-|-, Lys-|-, but CC with more restricted specificity than trypsin. CC -!- SUBUNIT: Homotetramer (By similarity). CC -!- SUBCELLULAR LOCATION: Released from the secretory granules upon CC mast cell activation (By similarity). CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=1; CC IsoId=Q9BZJ3-1; Sequence=Displayed; CC Name=2; CC IsoId=Q9BZJ3-2; Sequence=VSP_008319; CC -!- TISSUE SPECIFICITY: Expressed in colon, lung, heart and synovial CC tissue. May be specific to mast cells. CC -!- SIMILARITY: Belongs to peptidase family S1. Tryptase subfamily. CC -!- CAUTION: Although Ref.2 reported this as a pseudogene, Ref.4 CC showed it is expressed and has proteolytic activity when expressed CC in bacterial cells.
