PDBsumstructure summary

The envelope (E) protein is the smallest and least well-characterized of the four major structural proteins found in coronavirus virions.[2][3][4] It is an integral membrane protein less than 110 amino acid residues long;[2] in SARS-CoV-2, the causative agent of Covid-19, the E protein is 75 residues long.[5] Although it is not necessarily essential for viral replication, absence of the E protein may produce abnormally assembled viral capsids or reduced replication.[2][3] E is a multifunctional protein[6] and, in addition to its role as a structural protein in the viral capsid, it is thought to be involved in viral assembly, likely functions as a viroporin, and is involved in viral pathogenesis.[2][5]
