Tryptases comprise a family of trypsin-like serine
proteases, the peptidase family S1. Tryptases are enzymatically
active only as heparin-stabilized tetramers, and they are resistant
to all known endogenous proteinase inhibitors. Several tryptase
genes are clustered on chromosome 16p13.3. These genes are
characterized by several distinct features. They have a highly
conserved 3' UTR and contain tandem repeat sequences at the 5'
flank and 3' UTR which are thought to play a role in regulation of
the mRNA stability. These genes have an intron immediately upstream
of the initiator Met codon, which separates the site of
transcription initiation from protein coding sequence. This feature
is characteristic of tryptases but is unusual in other genes. The
alleles of this gene exhibit an unusual amount of sequence
variation, such that the alleles were once thought to represent two
separate genes, alpha and beta 1. Beta tryptases appear to be the
main isoenzymes expressed in mast cells; whereas in basophils,
alpha tryptases predominate. Tryptases have been implicated as
mediators in the pathogenesis of asthma and other allergic and
inflammatory disorders.1) Lee, J.W., et al. Dig. Dis. Sci. 55(10):2922-2928(2010)
