CC -!- FUNCTION: mRNA endonuclease involved in the No-Go Decay (NGD) pathway, CC which catalyzes mRNA cleavage and degradation in response to ribosome CC collisions (PubMed:31219035, PubMed:36583309). Acts downstream of the CC ribosome collision sensor HEL2 (PubMed:36583309). Specifically CC recognizes and binds RPS7/eS7 polyubiquitinated by MOT2/NOT4 and HEL2, CC promoting CUE2 recruitment to stalled ribosomes, where it mediates mRNA CC cleavage upstream of the colliding ribosome (PubMed:36583309). Also CC mediates mRNA cleavage within colliding ribosomes: recruited to CC colliding ribosomes downstream of the RQT (ribosome quality control CC trigger) complex following disassembly of stalled ribosomes and cleaves CC mRNAs partially released from the colliding ribosome (PubMed:36583309). CC {ECO:0000269|PubMed:31219035, ECO:0000269|PubMed:36583309}. CC -!- DOMAIN: The CUE domains specifically bind RPS7/eS7 polyubiquitinated by CC MOT2/NOT4 and HEL2. {ECO:0000269|PubMed:36583309}.
