Low thymine content in PINK1 mRNAs and insights into Parkinson's disease.

ABSTRACT: Thymine is the only nucleotide base which is changed to uracil upon transcription, leaving mRNA less hydrophobic compared to its DNA counterpart. All the 16 codons that contain uracil (or thymine in gene) as the second nucleotide code for the five large hydrophobic residues (LHRs), namely phenylalanine,v isoleucine, leucine, methionine and valine. Thymine content (i.e. the fraction of XTX codons, where X = A, C, G, or T) in PINK1 mRNA sequences and its relationship with protein stability and function are the focus of this work. This analysis will shed light on PINK1's stability, thus a clue can be provided to understand the mitochondrial dysfunction and the failure of oxidative stress control frequently observed in Parkinson's disease. We obtained the complete PINK1 mRNA sequences of 8 dif
