Anti-VEEV Spike glycoprotein E2 Polyclonal Antibody

Structural polyprotein (E2) is a ~138 kDa protein. Forms an icosahedral capsid with a T=4 symmetry composed of 240 copies of the capsid protein surrounded by a lipid membrane through which penetrate 80 spikes composed of trimers of E1-E2 heterodimers. The capsid protein binds to the viral RNA genome at a site adjacent to a ribosome binding site for viral genome translation following genome release. Possesses a protease activity that results in its autocatalytic cleavage from the nascent structural protein. Following its self-cleavage, the capsid protein transiently associates with ribosomes, and within several minutes the protein binds to viral RNA and rapidly assembles into icosahedric core particles. The resulting nucleocapsid eventually associates with the cytoplasmic domain of the spike glycoprotein E2 at the cell membrane, leading to budding and formation of mature virions.
