Preparation and Storage

Background: Airway Trypsin-like Protease/HAT

Human Airway Trypsin‑like protease (HAT), also known as Transmembrane Protease, Serine 11D (TMPRSSIID), is a type II transmembrane serine protease that is expressed in the cells of the submucosal serous glands of the bronchi and trachea (1‑3). The deduced sequence predicts a short cytoplasmic tail (aa 120), a transmembrane domain (aa 21‑41), and an ectodomain consisting of a SEA domain (aa 44‑164) and a catalytic domain (aa 187‑418). The single‑chain precursor can be converted into a disulfide‑linked two‑chains, one of which corresponds to the catalytic domain. HAT was initially purified from the sputum of patients with chronic airway diseases (1). HAT has been shown to induce PAR‑2 mediated IL‑8 release in psoriasis vulgaris and increase mucin expression in airway epithelial cells (4, 5). The amino acid sequence of human HAT is 99%, 79%, and 67% identical to that of chimpanzee, canine and rat/mouse.
