RQC trigger complex helicase SLH1

UniProtKB accession:  P53327

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in activation of the ribosome quality control (RQC) pathway, a pathway that degrades nascent peptide chains during problematic translation (PubMed:28757607, PubMed:28223409, PubMed:30893611, PubMed:32203490). Drives the splitting of stalled ribosomes that are polyubiquitinated in a HEL2-dependent manner, as part of the ribosome quality control trigger (RQT) complex (PubMed:28757607, PubMed:30893611, PubMed:32203490). Also represses the translation of non-poly(A) mRNAs together with SKI2 (PubMed:10922069). May block translation by inhibiting translation initiation factor 5B (FUN12) action on mRNAs lacking a 3' poly(A) structure (PubMed:11438647). Involved in antiviral defense, preventing L-A dsRNA virus propagation by specifically blocking translation of viral mRNAs (PubMed:10922069).
