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.

Homer binds TRPC family channels and is required for gating of TRPC1 by IP3 receptors.
Receptor signaling at the plasma membrane often releases calcium from intracellular stores. For example, inositol triphosphate (IP3) produced by receptor-coupled phospholipase C activates an intracellular store calcium channel, the IP(3)R. Conversely, stores can induce extracellular calcium to enter the cell through plasma membrane channels, too. How this "reverse" coupling works was unclear, but store IP(3)Rs were proposed to bind and ... [more]
