Synthesis pass · prose summary of the discoveries below

TMPRSS2 is a type II transmembrane serine protease, expressed under androgen receptor control predominantly in prostate and lung epithelia, that functions at the cell surface to proteolytically activate viral glycoproteins and endogenous substrates. Its serine protease domain cleaves the spike proteins of SARS-CoV-2, SARS-CoV, influenza hemagglutinin, and HCV entry factors, enabling plasma-membrane-route viral fusion; TMPRSS2 knockout in mice strongly reduces SARS-CoV-2 replication in the respiratory tract, and small-molecule inhibitors (camostat, nafamostat, N-0385) block this entry pathway (PMID:32142651, PMID:36243815, PMID:35344983). Beyond its catalytic role, TMPRSS2 serves as a proteinaceous entry receptor for HCoV-HKU1, binding the viral RBD through its catalytic groove even when proteolytically inactive, with structural rearrangements upon zymogen activation dramatically increasing binding affinity (PMID:37879362, PMID:38964326). In prostate cancer, recurrent chromosomal rearrangements fuse the androgen-responsive TMPRSS2 promoter to ETS family oncogenes (most commonly ERG), driving androgen-dependent ERG overexpression that recruits BAF chromatin-remodeling complexes genome-wide and promotes invasion through the plasminogen activation pathway (PMID:16254181, PMID:30078722, PMID:18283340).
