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.

Cbl-CIN85-endophilin complex mediates ligand-induced downregulation of EGF receptors.

Soubeyran P, Kowanetz K, Szymkiewicz I, Langdon WY, Dikic I

Cbl is a multi-adaptor protein involved in ligand-induced downregulation of receptor tyrosine kinases. It is thought that Cbl-mediated ubiquitination of active receptors is essential for receptor degradation and cessation of receptor-induced signal transduction. Here we demonstrate that Cbl additionally regulates epidermal growth factor (EGF) receptor endocytosis. Cbl rapidly recruits CIN85 (Cbl-interacting protein of 85K; ref. 6) and endophilins (regulatory components ... [more]
