Precursor messenger RNA is edited into its final form by an RNA–protein assembly called the spliceosome. Structural evidence provides insights into how the spliceosome is disassembled when its job is ...
Shown is the splicing pathway. The pre-messenger RNA (pre-mRNA) has exons (blue) and introns (pink). The spliceosome (not shown) was known to catalyze two chemical reactions (black arrows) in a ...
