This domain is found at the N-terminal end of E3 ubiquitin -protein ligase listerin from Saccharomyces cerevisiae (Ltn1) and similar eukaryotic proteins. Ltn1 is a component of the ribosome quality control complex (RQC), a ribosome-associated complex that mediates ubiquitination and extraction of incompletely synthesised nascent chains for proteasomal degradation. This domain is predominantly composed of alpha -helices that are arranged into HEAT repeats, each consisting of two antiparallel alpha-helices that pack against each other in a repeating array [1].
