Briefing: How an RNA-binding protein detects and responds to non-optimal codon usage in human cells

Human genes are structured as sequences of codons, which are three-letter units derived from four nucleotides. These codons are essential for specifying amino acids, the fundamental components of proteins.

Notably, there are multiple codons available to encode the same amino acid, which introduces variability in gene expression and protein synthesis.

RNA-binding proteins are integral to the cellular machinery, interpreting codon usage and responding to variations that may affect protein production efficiency.
