17. ...WHOA- the authors said the finding was “Unexpectedly” related to genes from HIV virus. Notably there were 4 gene insertions (see figure in above post #16). And so, which HIV gene proteins were found in the new
#coronarvirus? Gag protein and Gp120- key HIV proteins..
18. Notably, in virus' genome, authors say for HIV genome insertions: “Gag protein of HIV is involved in host membrane binding, packaging of the virus and for the formation of virus-like particles. Gp120 plays crucial role in recognizing the host cell by binding to the primary receptor CD4”
19. Again, these are new express published findings and not peer reviewed yet. Let’s not draw conclusions yet. But evidence suggest that 2 different HIV genes
are present in the #coronarvirus S gene region (that didn’t map to any other coronavirus, according to other studies).
20. Further the authors add that “This indicates that these insertions have been preferably acquired by the 2019-nCoV, providing it with additional survival and infectivity advantage. Delving deeper we found that these insertions were similar to HIV-1.”
21. Paper piles on: “these
insertions are present at binding site of 2019-nCoV. Due to presence of gp120 motifs in 2019-nCoV spike glycoprotein at its binding domain, we propose that these motif insertions could have provided an enhanced affinity towards host cell receptors.
22. The authors dunked this final conclusion: “This uncanny similarity of novel inserts in the 2019- nCoV spike protein to HIV-1 gp120 and Gag is unlikely to be fortuitous”. Wow, they sure just went straight there! What a bold paper... I don’t know what to say
