Ribosome quality control中cat tail
Webb6 juli 2024 · Abstract: The recent discovery that collision of ribosomes triggers quality control and stress responses in eukaryotes has shifted the perspective of the field. … Webb13 nov. 2024 · Summary. Stalled translation produces incomplete, ribosome-associated polypeptides that Ribosome-associated Quality Control (RQC) targets for degradation via the ubiquitin ligase Ltn1. During this process, the Rqc2 protein and large ribosomal subunit elongate stalled polypeptides with carboxy-terminal alanine and threonine residues (CAT …

WebbDescribed herein are compositions and techniques relating to the generation and therapeutic application of artificial synapses. Artificial synapses are engineered extracellular vesicles containing exosomes that are sticky on their surface to anchor signaling domains to biological targets such as receptors. Include a binder. 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.
WebbCollided ribosomes are specifically recognized to initiate stress responses and quality control pathways. Ribosome-associated quality control facilitates the degradation of … WebbRibosome-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
