The glucocorticoid receptor (GR) functions as a hormone-dependent transcription factor that is involved in the maintenance of basal and stress-related homeostasis. Serine 134 is a newly discovered phosphorylation target on the human glucocorticoid receptor that becomes phosphorylated during stress-activating conditions such as ultraviolet irradiation, nutrient starvation, and oxidative stress. The inventors have developed a rabbit polyclonal antibody that specifically recognizes the Ser 134 phosphorylated form of the human glucocorticoid receptor. This antibody may be particularly useful for a variety of basic research applications, such as the characterization and study of glucocorticoid signaling in cancer, inflammation, and other diseases.
The antibody is available as crude antisera and has been epitope purified; it has cross reactivity with human, rat, and mouse tissues.
