  • This SILAC-based approach allowed high-accuracy quantification of phosphopeptides and, in most cases, localisation of the phosphate group with single amino acid accuracy.

  • Cell lysates to be directly compared were pooled, fractionated and enzymatically digested into peptides, and phosphopeptides were enriched on TiO

  • Large-scale analyses of phosphopeptides are thus consistent with a cooperative function within the cluster.

  • In agreement with results reported here it has been shown recently that bacterially expressed HD-PTP catalytic domain was inert against a panel of 38 phosphopeptides and DiFMUP substrate

  • "Our results revealed successful selection and sequencing of phosphopeptides in proteolytic digests without affinity enrichment, as well as label-free quantitation of regulated protein phosphorylation events," concludes Dr. Ahn. "Further, we demonstrated pathway-dependent phosphorylation of FAM129B and discovered its importance in controlling melanoma cell invasion."

  • To determine if additional ERalpha phosphorylation sites exist, COS-1 cells expressing human ERalpha were labeled with [32P] H3PO4 in vivo and ERalpha tryptic phosphopeptides were isolated to identify phosphorylation sites.

  • Furthermore, using a proteomic approach in which phosphopeptides were identified from extracts of Drosophila Kc167 cells using mass spectroscopy, Aebersold and colleagues have detected phosphorylation on Ser533 of endogenous Tsc1, indicating that this site is phosphorylated in vivo by an unknown kinase (www. phosphopep.org [11]).
