Affinity Capture-Western

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 identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

IL-2 induces conformational changes in its preassembled receptor core, which then migrates in lipid raft and binds to the cytoskeleton meshwork.

While interleukin (IL)-2 clearly initiates the sequential assembly of its soluble receptor fragments (sIL-2R) in vitro (with sIL-2Rα first, sIL-2Rβ second, and sγc last), the assembly mechanism of full-length subunits (IL-2R) at the surface of living lymphocytes remains to be elucidated. Here we demonstrate by fluorescence cross-correlated spectroscopy that native IL-2Rβ and γc assemble spontaneously at the surface of living ... [more]
