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.

Radiation-induced phosphorylation of Chk1 at S345 is associated with p53-dependent cell cycle arrest pathways.

Tian H, Faje AT, Lee SL, Jorgensen TJ

Because DNA damage-inducible cell cycle checkpoints are thought to protect cells from the lethal effects of ionizing radiation, a better understanding of the mechanistic functions of cell cycle regulatory proteins may reveal new molecular targets for cancer therapy. The two major regulatory proteins of G2 arrest are Chk1 and p53. Yet, it is unclear how these two proteins interact and ... [more]

Additional Notes

  • Radiation-induced phosphorylation of Chk1 at S345 was associated with binding of Chk1 to p53, p21, and 14-3-3 sigma, and that UCN-01 inhibited S345 phosphorylation
