1.G.2.1.8
Fusion glycoprotein, F, of 111 aas and 1 C-terminal TMS as well as two small peaks of moderate hydrophobicity in the N-terminal and central regions of the protein. The trimeric fusion, F, glycoproteins of morbilliviruses are activated by furin cleavage of the precursor F₀ into the F₁ and F₂ subunits, and an additional membrane-proximal cleavage occurs and modulates F protein function (von Messling et al. 2004).
