TPSAB1 (Tryptase Alpha/Beta 1) is a gene encoding a subunit of tryptase, a serine protease predominantly expressed in mast cells. Mast cells play critical roles in allergic responses, immune regulation, and inflammation. Tryptase exists as a tetramer, primarily composed of β isoforms (β1. β2) encoded by TPSAB1. and to a lesser extent, α isoforms. TPSAB1-derived β-tryptase is stored in mast cell granules and released upon activation, contributing to tissue remodeling, pathogen defense, and inflammatory processes by cleaving proteins like fibrinogen, cytokines, and cell surface receptors.
Antibodies targeting TPSAB1 are essential tools for studying mast cell biology and associated diseases. They are widely used in immunohistochemistry, flow cytometry, and ELISA to detect mast cell presence, density, or activation states in tissues. Clinically, TPSAB1 antibodies aid in diagnosing mastocytosis, a disorder characterized by abnormal mast cell accumulation, by distinguishing pathological from normal mast cells. Elevated β-tryptase levels, detected via these antibodies, also correlate with systemic anaphylaxis severity.
Research applications include investigating mast cell involvement in asthma, chronic urticaria, and gastrointestinal disorders. Additionally, TPSAB1-targeting therapies are being explored, such as tryptase inhibitors for inflammatory diseases. However, interpreting results requires caution due to genetic variations (e.g., TPSAB1 duplication linked to hereditary α-tryptasemia) that influence tryptase levels. Overall, TPSAB1 antibodies bridge basic research and clinical diagnostics, enhancing understanding of mast cell-related pathologies.
