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.

Ubiquitination is an essential post-translational modification that mediates diverse cellular functions. SMAD-specific E3 ubiquitin protein ligase 1 (SMURF1) belongs to the Nedd4 family of HECT ubiquitin ligases that directly catalyzes ubiquitin conjugation onto diverse substrates. As a result, SMURF1 regulates a great variety of cellular physiologies including bone morphogenetic protein (BMP) signaling, cell migration, and planar cell polarity. Structurally, SMURF1 ... [more]
