Protein detail:


Protein name ORF7b
Uniprot protein ID -
Protein length 43 amino acids
Protein description ORF7b encodes a viral accessory protein. Based on its similarity to other coronavirus proteins, ORF7b protein is thought to localize to the Golgi compartment. The orf7b is a hydrophobic protein with a transmembrane domain N-terminal at the outside, and a cytoplasmic C-terminal. Similar to orf7a, orf7b is reported by the majority of the previous studies that it is not essential for virus replication.

Title E484K as an innovative phylogenetic event for viral evolution: Genomic analysis of the E484K spike mutation in SARS-CoV-2 lineages from Brazil
Author PatrĂ­cia Aline Grohs Ferrareze, Vinicius Bonetti Franceschi, Amanda de Menezes Mayer, Gabriel Dickin Caldana, Ricardo Ariel Zimerman
Evidence A hallmark of these Brazilian lineages is the presence of multiple lineage-defining mutations per lineage (Table 1 ).
