Most amino acids are encoded by multiple synonymous codons. Although alternative usage of synonymous codons does not affect the amino acid sequences of proteins, researchers have been reporting evidence for functional synonymous codon usage at the species- and gene-specific levels for over four decades. It has been shown that variations in synonymous codon usage can affect phenotypes through diverse mechanisms such as shaping translation efficiency and mRNA stability. On the other hand, the common view that cellular and organismal phenotypes are primarily determined by proteins whose functions are primarily determined by amino acid sequences, often drives the assumption that synonymous …
