Moderna owns the proprietary mRNA sequence found in SARS-CoV-2.
MSH3 Homology and Potential Recombination Link to SARS-CoV-2 Furin Cleavage Site
The presence in SARS-CoV-2 of a 19-nucleotide RNA sequence encoding an FCS at amino acid 681 of its spike protein with 100% identity to the reverse complement of a proprietary MSH3 mRNA sequence is highly unusual. Potential explanations for this correlation should be further investigated.
The correlation between this SARS-CoV-2 sequence and the reverse complement of a proprietary mRNA sequence is of uncertain origin. Conventional biostatistical analysis indicates that the probability of this sequence randomly being present in a 30,000-nucleotide viral genome is 3.21 ×10−11
