A ribosomal traffic jam that breaks the heart

Researchers found that a mutation in RPL3L, expressed only in heart and skeletal muscle, leads to impaired cardiac contractility by causing ribosomal collisions and protein folding abnormalities. The study aims to develop new treatments for cardiomyopathy and atrial fibrillation.

Lost in translation: How “risky” amino acids abort elongation in protein synthesis

A recent study published in Nature Communications reveals that nascent peptide chains with N-terminal sequences rich in aspartic acid or glutamic acid can lead to abortion of translation in eukaryotic cells through intrinsic ribosome destabilization (IRD). This phenomenon is associated with biased amino acid usage in proteomes, where t...
