WebDec 12, 2024 · The miRNA (green), TDMD trigger (teal), and AGO domains (N, PAZ, MID, and PIWI) are indicated. To test further the idea that these polyubiquitinated proteins were AGO proteins, as would be expected if the ZSWIM8 CRL directly targets AGO proteins during TDMD, we examined the effects of mutating AGO lysines that might serve as sites … Web2 days ago · This target RNA-directed miRNA degradation (TDMD) mechanism appears to be evolutionarily conserved, but recent studies have focused on mammalian systems. Here, we performed AGO1-CLASH in Drosophila S2 cells, with Dora (ortholog of vertebrate ZSWIM8) knockout mediated by CRISPR-Cas9 to identify five TDMD triggers …

Structural Basis for Target-Directed MicroRNA Degradation
WebTDMD target) promotes degradation of its miRNA17,18, accom- panied by post-transcriptional modification of the miRNA sequence, i.e., tailing (addition of nucleotides at the 3′ end) and WebJan 1, 2024 · Target-directed miRNA degradation (TDMD), which is triggered by extensive base-pairing of both the miRNA 5′ and 3′ end with a target, appears to be the major mechanism of regulated turnover of animal miRNAs. The ZSWIM8 ubiquitin ligase mediates TDMD by promoting the destruction of AGO:miRNA complexes engaged with highly … WebJan 31, 2024 · TDMD can selectively target specific miRNA family/cluster members. Features like complementarity to the miRNA 3’ region, bulge size and hybridization energy can explain the different sensitivity. A set of computational analyses performed using the multiomic TCGA platform support the involvement of TDMD in human cancer. Many … magrath funeral home obits
