功能： Cotranslational quality control factor involved in the No-Go Decay (NGD) pathway . In the presence of ABCE1 and HBS1L, is required for 48S complex formation from 80S ribosomes and dissociation of vacant 80S ribosomes . Together with HBS1L and in presence of ABCE1, recognizes stalled ribosomes and promotes dissociation of elongation complexes assembled on non-stop mRNAs; this triggers endonucleolytic cleavage of the mRNA, a mechanism to release non-functional ribosomes and to degrade damaged mRNAs as part of the No-Go Decay (NGD) pathway . As part of the PINK1-regulated signaling, upon mitochondrial damage is recruited to the ribosome/mRNA-ribonucleoprotein complex associated to mitochondrial outer membrane thereby enabling the recruitment of autophagy receptors and induction of mitophagy .
