  • 产品描述：

    E.coli-expressed human coronavirus OC43 (HCoV-OC43) spike glycoprotein (S) CSB-EP336163HIY is a recombinant fusion protein of partial HCoV-OC43-S coupled to a 6xHis-SUMO-tag at the N-terminus. This protein consists of the 15-344AA of HCoV-OC43-S and is calculated molecular weight of 53.9 kDa. The SDS-PAGE determined its purity over 90%. This recombinant HCoV-OC43-S protein is in-stock now.

    HCoV-OC43 S protein is essential for viral entry into the host and critically determines the tropism of host and tissue. It mediates the binding to cell-surface receptors. The S protein binds to sugar-based receptor-determinants, specifically to 9-O-acetylated sialic acids (9-O-Ac-Sias) attached as terminal residues to glycan chains on glycoproteins and lipids.

  • 功能：
    S1 attaches the virion to the cell membrane by interacting with sialic acid-containing cell receptors, initiating the infection.; attaches the virion to the cell membrane by interacting with host receptor, initiating the infection.; mediates fusion of the virion and cellular membranes by acting as a class I viral fusion protein. Under the current model, the protein has at least three conformational states: pre-fusion native state, pre-hairpin intermediate state, and post-fusion hairpin state. During viral and target cell membrane fusion, the coiled coil regions (heptad repeats) assume a trimer-of-hairpins structure, positioning the fusion peptide in close proximity to the C-terminal region of the ectodomain. The formation of this structure appears to drive apposition and subsequent fusion of viral and target cell membranes.; Acts as a viral fusion peptide which is unmasked following S2 cleavage occurring upon virus endocytosis.
