Two complexes of RNA-binding proteins, Sm and Lsm2–8, act sequentially on telomerase RNA during its biogenesis: the Sm ring promotes 3′-cleavage and facilitates hypermethylation of the 5′-cap, whereas the Lsm2–8 complex aids binding of the telomerase catalytic subunit and prevents degradation of the RNA.
