Slow editing of protein blueprints leads to cell death

A team of researchers has identified a mechanism that interferes with the splicing process in a more subtle way, leading to cell death. The study reveals that spliceosome subunits U4, U5, and U6 are normally stabilized by protein USP39, but when mutated or absent, stability is compromised, causing incorrect connections during splicing.

Oncotarget | Extreme phenotype approach identifies rare ATR variants as potential male breast cancer susceptibility alleles

Researchers have identified three novel pathogenic variants of the ATR gene as predisposing to male breast cancer. These variants were found in a cohort of individuals with early onset and familial breast cancers, using a combination of exome sequencing and functional investigations. The study suggests that extended genetic analysis ca...

Lariats: How RNA splicing decisions are made

Researchers at Brown University discovered over 800 tiny genetic loops, called lariats, in human tissues, providing new insights into RNA splicing decisions. The location of branchpoints on these lariats reliably predicts where splicing will occur, enabling the creation of an algorithmic model with 95.6% accuracy.
