SARS2 and HIV-1 3 peptide sequences exist SARS2 that: Are also found in the HIV-1 gp120 protein Have developed by natural evolution Form unresolved loops in the spike structure (Fig 馃憞) Have been reported to Fauci to bind CD4 Should anybody be interested in their function?

No the loops are not there (not inserted) in SARS1.

ok, thanks, but gp120 motifs do exist in various viruses, i will forward the reference

quite complex as it is not gp120 itself but smaller motifs 1. a section of sars-cov-2 spike protein that is very similar to HIV gp120 (glycoprotein) which allows sars-cov-2 to get into your brain 2. HIV gp120 sequence is itself similar to a cobra neurotoxin & rabies glycoprotein
