Quantitative detection of single amino acid polymorphisms by targeted proteomics

Abstract: Single-nucleotide polymorphisms (SNPs) are recognized as one kind of major genetic variants in population scale. However, polymorphisms at the proteome level in population scale remain elusive. In the present study, we named amino acid variances derived from SNPs within coding regions as single amino acid polymorphisms (SAPs) at the proteome level, and developed a pipeline of non-targeted and targeted proteomics to identify and quantify SAP peptides in human plasma. The absolute concentrations of three selecte… Show more

“…Osteopontin splice variants were identified and quantified using MRM-MS [16]; novel proteoforms of prostate specific antigen were also identified in clinical samples via MRM-MS [17]. In a larger population study, the concentration of three selected single amino acid polymorphism peptides, representing the Complement Component C7, Complement Factor H, and Complement Component C5 proteins, were measured by SRM-MS from 290 individuals [18]. In another population study, serum peptide variations were studied in 500 healthy individuals using a regular MS analysis (without trypsin digestion), but the peptides detected were exopeptidase products derived from relatively abundant serum proteins [19].…”

“…Предпосылки для указанного подхода созданы в ряде исследований, демонстрирующих возможности протеомной идентифи-кации и оценки связи некоторых модифицированных белков с заболеваниями. Так, посредством направленной масс-спектрометрии проводили количественный анализ пептидов с SAP, ассоциированными с развитием сахарного диабета и ожирения [47]. Кроме того, разработана стра-тегия поиска методами протеомики новых и известных вариантов сплайсинга белков, ассоциированных с возникновением рака поджелудочной и молочной железы [48].…”
