MicroRNAs direct downregulation of target mRNAs. Sometimes, however, this regulatory paradigm inverts, and a target RNA triggers the degradation of a microRNA. This target-directed microRNA degradatio...

Most eukaryotic mRNAs contain a poly(A) tail, which in post-embryonic cells enhances their stability. Many cytoplasmic RNA viruses also harbor poly(A) tails on their genomic RNA and mRNAs. Here, we re...

Autophagy targets a wide variety of substrates for degradation within lysosomes. While lysosomes are known to possess RNase activity, the role of lysosomal RNA degradation in post-transcriptional gene...

Lysosomal uptake of mtDNA controls mitochondrial quality.

Exogenous messenger RNAs (mRNAs) require cellular machinery for delivery and translation but also encounter inhibitory factors. To investigate their regulation, we performed genome-wide CRISPR screens...

MicroRNAs (miRNAs) associate with Argonaute (AGO) proteins to serve as guides, directing binding to partially complementary sites in mRNAs, ultimately causing post-transcriptional repression. Compleme...

Transcriptome-wide mapping of snoRNA targets reveals mRNA-snoRNA-7SL RNA ternary interactions, which facilitate nascent protein translocation to the ER and subsequent secretion.
