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.

Estrogen Receptor alpha (ER?) is a ligand-inducible transcription factor that mediates estrogen signaling in hormone-responsive cells, where it controls key cellular functions by assembling in gene-regulatory multiprotein complexes. For this reason, interaction proteomics has been shown to represent a useful tool to investigate the molecular mechanisms underlying ER? action in target cells. RNAs have emerged as bridging molecules, involved in ... [more]

Additional Notes

  • interaction detected using the TAP (tandem affinity purification) procedure followed by LC-MS/MS (liquid chromatography-tandem mass spectrometry) to identify ER-alpha-interacting proteins; this interaction was detected in at least 2 of 3 samples not treated with, as well as in at least 2 of 3 samples pre-treated with, RNase, suggesting that the interaction can occur in the absence or presence of RNA; this interaction was considered statistically significant because (a) a p-value of p<0.05 was obtained using the Mascot software and (b) a high or medium protein FDR (false discovery rate) confidence level was reported using the ProteomeDiscoverer software
