The mutations of Rqt2 in the conserved residues in ATPase domain diminished RQC. a Alignment of the conserved residues in the RecA1 motif I of Slh1/Rqt2, Brr2, Ski2, and hRad51. The substitution of the lysine to arginine residue of motif I in human Rad51 diminished the ATPase activity37. b The mutations of Rqt2 in the conserved residues in ATPase domain diminished RQC. c Rqt2-3 were distributed in heavy polysome fraction in Rqt2K316R mutant. d The expression levels of endogenously HA-tagged Rqt2, Rqt2-K316R, Rqt3, and Rqt4 proteins in Rqt2-K316R mutant cells
