![]() | ![]() タイトル: UFMylation orchestrates spatiotemporal coordination of RQC at the ER. 著者: Ivan Penchev / Samantha Gumbin / Francesco Scavone / Otto Berninghausen / Thomas Becker / Ron Kopito / Roland Beckmann / ![]() ![]() 要旨: Degradation of arrest peptides from endoplasmic reticulum (ER) translocon-bound 60 ribosomal subunits via the ribosome-associated quality control (ER-RQC) pathway requires covalent modification of ...Degradation of arrest peptides from endoplasmic reticulum (ER) translocon-bound 60 ribosomal subunits via the ribosome-associated quality control (ER-RQC) pathway requires covalent modification of RPL26/uL24 on 60 ribosomal subunits with UFM1. However, the underlying mechanism that coordinates the UFMylation and RQC pathways remains elusive. Structural analysis of ER-RQC intermediates revealed concomitant binding and direct interaction of the UFMylation and RQC machineries on the 60. In the presence of an arrested peptidyl-transfer RNA, the RQC factor NEMF and the UFM1 E3 ligase (E3) form a direct interaction via the UFL1 subunit of E3, and UFL1 adopts a conformation distinct from that previously observed for posttermination 60. While this concomitant binding occurs on translocon-bound 60, LTN1 recruitment and arrest peptide degradation require UFMylation-dependent 60 dissociation from the translocon. These data reveal a mechanism by which the UFMylation cycle orchestrates ER-RQC. | ||||||||||||
