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.

Modulation of human checkpoint kinase Chk1 by the regulatory beta-subunit of protein kinase CK2.

Guerra B, Issinger OG, Wang JY

Protein kinase CK2 is a serine/threonine protein kinase involved in various aspects of cellular regulation. The regulatory beta-subunit of CK2 exerts a central role not only in mediating formation of tetrameric CK2 complexes but also as a docking partner for several protein kinases. In this study, CK2beta is found to interact with the human cell cycle checkpoint kinase Chk1. The ... [more]

Additional Notes

  • CK2beta is found to interact with the human cell cycle checkpoint kinase Chk1. The Chk1-interacting region of CK2beta is localized at the C-terminus and the complex between CK2beta and Chk1 is devoid of the catalytic CK2alpha-subunit
