GeneMedi pseudotyped virus (pseudovirus) of SARS-COV-2 (2019nCOV) 501Y.V2 lineage

Background Reading: Information and products collection of SARS-COV-2 (2019nCOV) South Africa 501Y.V2 lineage

The world is in midst of the COVID-19 pandemic. Recently a new SARS-CoV-2 (2019nCOV)lineage (501Y.V2,B.1.351), characterised by eight lineage-defining mutations in the spike protein (excluding D614G mutation), including three at important residues in the receptor-binding domain (K417N, E484K and N501Y), represents increased transmissibility. This lineage emerged in South Africa and spread rapidly, becoming within weeks the dominant lineage in the Eastern Cape and Western Cape Provinces of South Africa.

Mutations of Spike protein in SARS-COV-2 (2019nCOV) 501Y.V2 lineage(B.1.351) (B.1.351) spread in South Africa

Three of the spike mutations are at key residues in the RBD (N501Y, E484K and K417N), three are in the N-terminal domain (L18F, D80A and D215G) and one is in loop 2 (A701V). Deletion of three amino acids at L242-244L is disputed with a L242H mutation¹.
