It starts as a precursor protein, which is glycosylated in the Golgi apparatus. Finally, it is cleaved by a cellular furin protease into the mature SU (roughly 70 kDa) and TM (Transmembrane) subunits. maturesu s a
SU (Surface) is a glycoprotein that mediates viral adsorption by binding to specific receptors on a cell surface. Think of it as the virus's "lock-picking" tool. Ever wonder how a virus actually gets inside a cell
