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.

Phosphorylation of cyclin Y by CDK14 induces its ubiquitination and degradation.

Li S, Song W, Jiang M, Zeng L, Zhu X, Chen J

Cyclin Y, a membrane associated cyclin, is capable of binding and activating CDK14. Here we report that human cyclin Y (CCNY) is a phosphoprotein in vivo and that phosphorylation of CCNY by CDK14 triggers its ubiquitination and degradation. Inactivation of either CDK14 or Cul1 results in accumulation of CCNY. An in vivo and in vitro mapping of CCNY phosphorylation sites ... [more]
