Ribosome quality control中cat tail
Webb28 jan. 2024 · We found that eight consecutive tryptophan residues located at the discrimination gate of the ribosome tunnel inhibited CAT-tailing, suggesting that steric hindrance between the constriction site of the ribosome tunnel and the nascent polypeptides inhibits CAT-tailing in the 60S subunit.

When translation … Webb5 jan. 2024 · Ribosome-associated quality control (RQC) relieves stalled ribosomes and eliminates potentially toxic nascent polypeptide chains (NCs) that can cause neurodegeneration. During RQC, RQC2 modifies NCs with a C-terminal alanine and threonine (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
