Two perpendicular views are shown. Components of the P complex are color-coded and tabulated below the structure. NTC: NineTeen complex; NTR: NTC-related complex. b Structure of the human ILS complex 1 (ILS1) at an average resolution of 2.91£¿£¿. The ATPase/helicase Prp43 is yet to be loaded in the ILS1 complex. c Structure of the human ILS complex 2 (ILS2) at an average resolution of 2.86£¿£¿. Prp43 is present in the ILS2 complex, ready to disassemble the spliceosom %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6461851/
