Codon Usage Biases in Alzheimer's Disease and Other Neurodegenerative Diseases
Establishing codon usage biases are crucial for understanding the etiology of central nervous system neurodegenerative diseases (CNSNDD) especially Alzheimer's disease (AD) as well as genetic factors. G and C ending codons are strongly biased in the coding sequences of these proteins as a result of genomic GC composition constraints. On the other hand, codons that identified as translationally optimal in the major trend all end in C or G, suggesting translational selection should also be taken into consideration additional to compositional constraints. Furthermore, this investigation reveals that three common codons, CGC (Arg), AGC (Ser), and GGC (Gly), are also critical in affecting codon usage bias. They not only can offer an insight into the codon usage bias of AD and its mechanism, but also may help in the possible cures for these diseases.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
