It is shown that RTTN has an unrecognized function at the core of the translation machinery and is enriched in cycling first-trimester neural progenitors and physically associates with ribosome-biogenesis and RNA-processing factors.
The nucleolus is a membraneless nuclear organelle formed by liquid-liquid phase separation and serves as the hub for ribosomal RNA (rRNA) transcription and ribosome assembly. Here, we identify ALKBH3, a Fe(II)/α-ketoglutarate-dependent dioxygenase, as a previously unrecognized nucleolar protein that colocalizes with th...

These findings establish TMEM107 and RFX7 as key components of the molecular pathway linking U4atac dysfunction to ciliary defects and impaired brain development, providing new physiopathological insights and therapeutic perspectives for RNU4ATAC-related disorders.

Summary Despite ribosomal protein loss correlating with increased tumor predisposition, direct mechanisms for the counterintuitive oncogenic effect of ribosomal protein depletion have not been reported. We used genetic models to investigate ribosomal protein S19a (RpS19a) depletion in the Drosophila blood organ, the ly...

Cryo-electron microscopy reveals a conserved role for RPL41 in maintaining ribosome dynamics and translational fidelity, indicating that RPL41 supports ribosome function and long-protein homeostasis in mammals.

Long noncoding RNAs (lncRNAs) are well recognized as regulators of neuronal development and function, yet their integration into canonical axonal transport pathways, an essential component of spatial gene regulation in highly polarized cells, remains incompletely defined. It is still unclear to what extent individual l...
