Allele-Specific Protein Abundance in Human Brain


ABSTRACT: We describe a method for identifying peptides that result from missense changes and identify peptides among 2 human brains that would have otherwise not been detected. Next, we use this data to estimate of allele-specific protein abundance in human brain for an average per individual, and to estimate apolipoprotein E allele specific abundance in human brain across individuals. Finally, we estimate the heritability of allele-specific protein abundance.

Gene expression contributes to phenotypic traits and human disease. To date, comparatively less is known about regulators of protein abundance, which is also under genetic control and likely influences clinical phenotypes. However, identifying and quantifying allele-specific protein abundance by bottom-up proteomics is challenging since single nucleotide variants (SNVs) that alter protein sequence are not considered in standard human protein databases. To address this, we developed the GenPro so  ...[more]
