Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Quantitative dissection and stoichiometry determination of the human SET1/MLL histone methyltransferase complexes.

van Nuland R, Smits AH, Pallaki P, Jansen PW, Vermeulen M, Timmers HT

Methylation of lysine 4 on histone H3 (H3K4) at promoters is tightly linked to transcriptional regulation in human cells. At least six different COMPASS-like multisubunit (SET1/MLL) complexes that contain methyltransferase activity for H3K4 have been described, but a comprehensive and quantitative analysis of these SET1/MLL complexes is lacking. We applied label-free quantitative mass spectrometry to determine the subunit composition and ... [more]
