Tryptases are serine proteases with trypsin-like specificity. Together with chymases and Cathepsin G, tryptases are important players in mast cell mediation of inflammatory and allergic responses. Tryptase alpha beta-1(TPSAB1), also known as mast cell protease 7 (MCPT7), it exhibits anticoagulant activity due to its ability to degrade fibrinogen in the presence of a diverse array of protease inhibitors in plasma. The two Isoform 1 and isoform 2 are expressed in lung, stomach, spleen, heart and skin; in these tissues, isoform 1 is predominant. Isoform 2 is expressed in aorta, spleen, and breast tumor, with highest levels in the endothelial cells of some blood vessels surrounding the aorta, as well as those surrounding the tumor and low levels, if any, in mast cells. Isoform 2 cleaves large substrates, such as fibronectin, more efficiently than isoform 1, but seems less efficient toward small substrates. It may play a role in innate immunity.

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. TPSAB1 Protein, Mouse, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 30.1 kDa and the accession number is Q02844.

TPSAB1, namely tryptase alpha beta-1, is a serine protease with trypsin­like activity. TPSAB1 is the major neutral protease present in mast cells and is secreted upon the coupled activation-degranulation response of this cell type. It may play a role in innate immunity. Diseases associated with TPSAB1 include mastocytosis and systemic mastocytosis.

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. TPSAB1 Protein, Rat, Recombinant (His & Myc & SUMO) is expressed in E. coli expression system with N-10xHis-SUMO and C-Myc tag. The predicted molecular weight is 47.4 kDa and the accession number is P27435.
