Protein: RQC trigger complex subunit CUE3 (P53137)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Involved in activation of the ribosome quality control (RQC) pathway, a pathway that degrades nascent peptide chains during problematic translation. Specifically recognizes and binds RPS20/uS10 ubiquitinated by HEL2, promoting recruitment of the RQT (ribosome quality control trigger) complex on stalled ribosomes, followed by disassembly of stalled ribosomes
Subcellular location: Cytoplasm
