While the SP domain is responsible for the actual "cleaving" or priming of the viral spike protein, the serves as a vital structural anchor within the ectodomain. Understanding the specific sequence from 112 to 149 is essential for researchers attempting to produce fully active, refolded versions of the protein in laboratory settings, such as using Escherichia coli expression systems. Scientific Significance in Drug Discovery

The human TMPRSS2 (Transmembrane Protease, Serine 2) is composed of three distinct extracellular domains: SRCR Domain (Residues 150–242) Serine Protease (SP) Domain (Residues 243–492) 112149

Efficient production of fully active, SARS-CoV-2-priming ... - PMC While the SP domain is responsible for the

The precise mapping of these residues allows scientists to target the protein more effectively. Because TMPRSS2 is a host cell protease that the COVID-19 virus uses to enter human cells, it is an attractive target for . - PMC The precise mapping of these residues

Research utilizing computational tools like molecular docking and MD simulations has even explored how natural compounds—such as certain alkaloids—might interact with these specific protein structures to inhibit the virus's ability to infect a host. By focusing on the structural integrity provided by regions like the 112–149 domain, developers can better design medicines that potentially block the pathways utilized by SARS-CoV-2.
