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.

Degradation of Cep68 and PCNT cleavage mediate Cep215 removal from the PCM to allow centriole separation, disengagement and licensing.

An intercentrosomal linker keeps a cell's two centrosomes joined together until it is dissolved at the onset of mitosis. A second connection keeps daughter centrioles engaged to their mothers until they lose their orthogonal arrangement at the end of mitosis. Centriole disengagement is required to license centrioles for duplication. We show that the intercentrosomal linker protein Cep68 is degraded in ... [more]
