1.C.99.1.4
ORF8 protein of 121 aas and 1 N-terminal TMS. Orf8 is a short 29-amino-acid single-passage transmembrane peptide that forms cation-selective channels when assembled in lipid bilayers (Barrantes 2021). A cell-based system combined with flow cytometry can be used to evaluate antibody responses against SARS-CoV-2 transmembrane proteins in patients with COVID-19 (Martin et al. 2022).
