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.

Mitotic regulation of the stability of microtubule plus-end tracking protein EB3 by ubiquitin ligase SIAH-1 and Aurora mitotic kinases.

Microtubule plus-end tracking proteins (+TIPs) control microtubule dynamics in fundamental processes such as cell cycle, intracellular transport, and cell motility, but how +TIPs are regulated during mitosis remains largely unclear. Here we show that the endogenous end-binding protein family EB3 is stable during mitosis, facilitates cell cycle progression at prometaphase, and then is down-regulated during the transition to G(1) phase. ...
