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.

Cool-1 functions as an essential regulatory node for EGF receptor- and Src-mediated cell growth.

Feng Q, Baird D, Peng X, Wang J, Ly T, Guan JL, Cerione RA

Cool-1 (cloned-out of library 1) has a key role in regulating epidermal growth factor receptor (EGFR) degradation. Here, we show that Cool-1 performs this function by functioning as both an upstream activator and downstream target for Cdc42. EGF-dependent phosphorylation of Cool-1 enables it to act as a nucleotide exchange factor for Cdc42 and to form a complex with the E3 ... [more]
