背景信息

TPSAB1 (Tryptase Alpha/Beta 1) is a gene encoding a member of the tryptase serine protease family, primarily expressed in mast cells. Mast cell tryptases, including the TPSAB1-derived β1 isoform, play critical roles in immune responses, particularly in allergic reactions, asthma, and host defense. These proteases are stored in mast cell granules and released upon activation, contributing to extracellular matrix degradation, inflammation, and tissue remodeling through cleavage of substrates like fibrinogen, cytokines, and protease-activated receptors (PARs). TPSAB1 has garnered attention due to its involvement in mast cell-mediated pathologies and potential as a therapeutic target.

Recombinant TPSAB1 protein is produced using biotechnological systems (e.g., mammalian or insect cell lines) to ensure proper post-translational modifications, including tetramer formation essential for enzymatic activity. This engineered protein serves as a vital tool for studying tryptase functions, inhibitor screening, and elucidating mechanisms in mast cell disorders. For example, it enables researchers to analyze substrate specificity, evaluate drug candidates for allergic diseases, and investigate genetic variants linked to conditions like mast cell activation syndrome (MCAS), where TPSAB1 duplication or overexpression is implicated.

Additionally, recombinant TPSAB1 aids in structural studies, providing insights into active-site conformations to guide rational drug design. Its applications extend to biomarker research, as elevated tryptase levels in blood correlate with systemic mastocytosis and anaphylaxis severity. Despite challenges in maintaining stability during production, recombinant TPSAB1 remains indispensable for advancing mast cell biology and developing targeted therapies against tryptase-driven diseases.
