Crystal structure of the ubiquitin binding domains of rabex-5 reveals two modes of interaction with ubiquitin.

The interaction between ubiquitinated proteins and intracellular proteins harboring ubiquitin binding domains (UBDs) is critical to a multitude of cellular processes. Here, we report that Rabex-5, a guanine nucleotide exchange factor for Rab5, binds to Ub through two independent UBDs. These UBDs determine a number of properties of Rabex-5, including its coupled monoubiquitination and interaction in vivo with ubiquitinated EGFRs. ... [more]

Affinity Capture-Western
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.
