Chk2 thr68
WebSep 12, 2000 · In vivo, Thr68 is phosphorylated in an ATM-dependent manner in response to IR, but not in response to UV or HU. Substitution of Thr68 with Ala reduced the extent of phosphorylation and activation of Chk2 in response to IR, and mutation of all seven SQ/TQ motifs blocked all phosphorylation and activation of Chk2 after IR. WebThe Phospho-Chk2 (Thr68) Antibody from Cell Signaling Technology is a Rabbit Polyclonal antibody. This antibody recognizes Human, and Non-Human Primate antigen. The Phospho-Chk2 (Thr68) Antibody has been validated for the following applications: Precipitation, Flow Cytometry, Immunoprecipitation, and Western Blot.
