Confocal image showing cytoplasmic and membranous staining in 293T cells transfected with a MERS-CoV Spike glycoprotein protein expression vector containing a myc-His-tag® (shown in green) but no staining in 293T cells transfected with a SARS-CoV-2 Spike glycoprotein vector containing a myc-His-tag®. The counterstain was observed in magenta. Nuclear DNA was labeled with DAPI (shown in blue).
Image was taken with a confocal microscope(Leica-Microsystems, TCS SP8).

補足情報

This supplementary information is collated from multiple sources and compiled automatically.

The MERS-CoV Spike glycoprotein also known as MERS-CoV S protein serves as an essential element for viral entry into host cells. It has a molecular mass of approximately 135 kDa and is expressed on the surface of the Middle East Respiratory Syndrome Coronavirus (MERS-CoV). This glycoprotein facilitates the attachment of the virus to the host cell receptor specifically the dipeptidyl peptidase 4 (DPP4) initiating the fusion process required for viral entry.
Biological function summary

The Spike glycoprotein of MERS-CoV enables the virus to penetrate host cellular membranes. It functions as a trimeric complex where each monomer consists of two functional subunits S1 and S2. The S1 subunit contains the receptor-binding domain while the S2 subunit is responsible for membrane fusion. The coordination of these activities allows the virus to successfully infect host cells and propagate within the infected organism.

Pathways

The MERS-CoV Spike glycoprotein plays a vital role in the viral entry and fusion pathways. It interacts with the host receptor DPP4 allowing the virus to exploit the host's endosomal and fusion pathways for cellular entry. The S2 subunit's fusion peptide cooperates with other viral proteins such as the viral envelope proteins to enable the fusion of viral and cellular membranes influencing the viral replication cycle significantly.

The MERS-CoV Spike glycoprotein is closely associated with MERS a severe respiratory illness. The interaction of this glycoprotein with DPP4 is central to the pathogenesis of MERS facilitating the virus's ability to infect human hosts and cause disease. Furthermore this glycoprotein's ability to mutate plays a role in the variability of viral infectivity and virulence posing challenges for vaccine and therapeutic developments.

ターゲットの情報

Spike protein S1. Attaches the virion to the cell membrane by interacting with host receptor, initiating the infection (By similarity). Interacts with host DPP4 to mediate virla entry.. Spike protein S2. 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.. Spike protein S2'. Acts as a viral fusion peptide which is unmasked following S2 cleavage occurring upon virus endocytosis.
