Recombinant Bat SARS-like coronavirus/HKU3-1 S(RBD) protein

• Cat.No.: bSARSlS-121V
• Product Overview: Purified recombinant Bat SARS-like coronavirus/HKU3-1 S(RBD) protein was expressed in HEK293 cells.

Specification

• Species: BtCoV
• Source: HEK293
• Description: Spike protein S1: Attaches the virion to the cell membrane by interacting with host receptor, initiating the infection.
  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.
