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.

Sumoylated BubR1 plays an important role in chromosome segregation and mitotic timing.

Yang F, Huang Y, Dai W

BubR1 is an important component of the spindle assembly checkpoint, and deregulated BubR1 functions frequently result in chromosomal instability and malignant transformation. We recently demonstrated that BubR1 was modified by sumoylation, and that lysine 250 (K250) functions as the crucial site for this modification. BubR1 sumoylation was neither required for its activation nor for binding to kinetochores. However, ectopically expressed ... [more]
