Proteome News and Research

RSS

The proteome is the entire complement of proteins expressed by a genome, cell, tissue or organism. More specifically, it is the expressed proteins at a given time point under defined conditions. The term is a blend of proteins and genome.

Antibody recognition of linear SARS-CoV-2 epitopes preserved in mutated B.1.1.7 strain

In a recent medRxiv research paper, the US scientists examined the effects of non-synonymous mutations in the circulating B.1.1.7 strain of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on linear antibody epitope signal for viral spike glycoprotein and nucleoprotein – and demonstrated that mutations should not result in immune evasion.
