Although s2m is not universally present among coronaviruses and appears to undergo horizontal transfer, the high sequence conservation and universal presence of s2m among isolates of SARS-CoV-2 indicate that, when present, the element is essential for viral function. The presence of s2m in the SARS-CoV-2 genome (GenBank accession MN908947, position 29727-29768) and other members of this group is probably the result of a single horizontal transfer event, predating the divergence of the SARS-related viruses (Tengs, et al. The insect species that contain s2m (and the associated protein) are distantly related, indicating either a deep evolutionary origin with multiple losses or that this genetic construct is also a mobile element, perhaps using viruses as a vector .	./cache/cord-328695-nptfd6c2.txt	./txt/cord-328695-nptfd6c2.txt
