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.

Human Multisubunit E3 Ubiquitin Ligase Required for Heterotrimeric G-Protein ?-Subunit Ubiquitination and Downstream Signaling.

Young BD, Sha J, Vashisht AA, Wohlschlegel JA

G-protein-coupled receptors (GPCRs) initiate intracellular signaling events through heterotrimeric G-protein ?-subunits (G?) and the ??-subunit dimer (G??). In this study, we utilized mass spectrometry to identify novel regulators of G?? signaling in human cells. This prompted our characterization of KCTD2 and KCTD5, two related potassium channel tetramerization domain (KCTD) proteins that specifically recognize G??. We demonstrated that these KCTD proteins ... [more]
