LFQ of UMR106 pY-IP


ABSTRACT: UMR106 cells were untreated or treated with 5 mM Pi or 100 ng/ml FGF2 for 15 min. The lysates were digested with trypsin, and tyrosine-phosphorylated peptides were enriched by anti-phosphotyrosine antibody and subjected to LC-MS/MS analysis. Raw data were directly analyzed against the SwissProt database restricted to Rattus using Proteome Discoverer version 2.2 for identification and label-free precursor ion quantification.

Fibroblast growth factor (FGF) 23 produced by bone is a hormone that decreases serum phosphate (Pi). Reflecting its central role in Pi control, serum FGF23 is tightly regulated by serum Pi alterations. FGF23 levels are regulated by the transcriptional event and posttranslational cleavage into inactive fragments before its secretion. For the latter, O-glycosylation of FGF23 by <i>GALNT3</i> gene product prevents the cleavage, leading to an increase in serum FGF23. However, the molecular basis of  ...[more]
