Protein

Tryptase beta-2

Gene

TPSB2

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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).By similarity

Catalytic activityi

Preferential cleavage: Arg-|-Xaa, Lys-|-Xaa, but with more restricted specificity than trypsin.

Interactioni

Subunit structurei

Homotetramer. The active tetramer is converted to inactive monomers at neutral and acidic pH in the absence of heparin. Low concentrations of inactive monomers become active monomers at pH 6.0 in the presence of heparin. When the concentration of active monomers is higher, they convert to active monomers and then to active tetramers. These monomers are active and functionally distinct from the tetrameric enzyme. In contrast to the hidden active sites in the tetrameric form, the active site of the monomeric form is accessible for macromolecular proteins and inhibitors eg: fibrinogen which is a substrate for the monomeric but not for the tetrameric form. The monomeric form forms a complex with SERPINB6.1 Publication

Polymorphismi

There are two alleles; beta-II and beta-III. Beta-II is the most commun allele. There are two forms of the beta-III allele, a short and a long form. The short form (also named frameshifted form) is carried by 23% and 19% of individuals of European and African ancestry but 0% of Asian subjects. In the human genome reference version GRCh37/hg19, the allele beta-III short form is represented.
