Abstract
- BACKGROUND Within the sulfotransferase (SULT) superfamily of metabolic enzymes, SULT1A1 and 1A3/4 isoforms are of particular interest, due to their abilities to catalyze the sulfation of phenolic endobiotics and xenobiotics. Although the difference in their substrate specificity is well documented, an isoform-specific quantification method is still not available. OBJECTIVE To detect and quantify SULT1A1 and 1A3/4 in S9 fractions and cell lines using targeted mass spectrometry-based proteomics. METHOD Samples were tryptically digested, and signature peptides were quantified using liquid chromatography- multiple reaction monitoring mass spectrometry (LC-MRM/MS). Stable isotopelabeled (SIL) peptides were used as internal and calibration standards. SULT1A1 and SULT1A3/4 were quantified in various S9 fractions and cell line samples. RESULTS Intraday and interday variabilities were low for relative quantification in S9 and cell line matrices (
