Transmembrane protease serine 2 (TMPRSS2), associated with the plasma membrane of the host cell, mediates the hydrolytic cleavage of SARS-CoV-1 Spike (S) protein component of the viral membrane-associate S3:M:E:encapsidated SARS coronavirus genomic RNA: 7a:O-glycosyl 3a tetramer complex associated with ACE2 (Matsuyama et al. 2010; Glowacka et al. 2011; Shulla et al. 2011).
