Ribosome quality control中cat tail

Webb27 maj 2024 · Off the ribosome, CAT tails act as degrons to mark those escaped RQC substrates for proteasomal degradation, independently of Ltn1. For the substrates we analyzed, Ltn1-independent degradation required the E3 ubiquitin ligase Hul5. Results CAT tails aid decay of RQC substrates Webb31 maj 2024 · In eukaryotes, this function is carried out by a dedicated surveillance mechanism known as ribosome-associated protein quality control (RQC). The E3 ubiquitin ligase Ltn1 (listerin in mammals) plays a key part in RQC by targeting the aberrant nascent polypeptides for proteasomal degradation.
