Fascinating 🧵. The grotesquely mutated spike of this NJ Cryptic binds ACE2 very tightly.
It raises a broader question: Can cryptic wastewater-like lineages transmit?
YES
We knew it happened once. Now we know it's happened at least twice. The results in both cases were not pretty. 1/15

This is wild.
Remember the NJ crytic lineage?
I posted 18 months ago that the Spike was too divergent to predict ACE2 binding, and asked if someone else could figure it out.
Some colleagues took me up on it.
Guess what they found?
