WebDec 1, 2024 · The most conserved NMD factors are up-frameshift proteins ( UPF) UPF1, UPF2 and UPF3B. The human NMD machinery additionally is comprised of suppressors with morphogenetic effects on genitalia (SMG) proteins including SMGs 1, 5, 6, 7, 8, and 9. SMG1 forms a complex with SMG8 and SMG9 which downregulate SMG1’s kinase activity [ 35 ].
