Phospho RSK1 (Thr573) Alpha SureFire Ultra Detection kit, 10K

Serine/threonine-protein kinase acts downstream from ERK (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenic and stress-induced activation of the transcription factors CREB1, ETV1/ER81, and NR4A1/NUR77. It regulates translation through RPS6 and EIF4B phosphorylation and mediates cellular proliferation, survival, and differentiation by modulating mTOR signaling and repressing the pro-apoptotic function of BAD and DAPK1. 

Upon extracellular signal or mitogen stimulation, RSK1 is phosphorylated at Thr-573 in the C-terminal kinase domain (CTD) by MAPK1/ERK2 and MAPK3/ERK1.

The AlphaLISA® SureFire® Ultra™ Phospho-RSK1 (Tyr573) assay is a sandwich immunoassay for quantitative detection of phospho-RSK1 in cellular lysates using Alpha Technology.
