RSK1 Antibody Summary

This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to a C-terminal region of human RSK1 protein.
This antibody is directed against the human RSK1 protein. A BLAST analysis was used to suggest cross reactivity with RSK1 proteins.
Immunogen affinity purified

  • Western Blot 1:200-1:1000
  • ELISA 1:2000-1:5000
Application Notes
This affinity purified antibody has been tested for use in ELISA, western blot, and immunoprecipitation. Expect a predominant band approximately 88 kDa in size corresponding - RSK1 by western blotting in the appropriate cell lysate or extract.

Reactivity Notes

Cross reactivity with RSK1 (and partial reactivity against RSK2 and RSK3) from other sources may occur but has not been tested.

RSK1 is a member of a family of 90kDa ribosomal protein S6 kinases, which includes Rsk1, Rsk2 and Rsk3. These are broadly expressed serine/threonine protein kinases activated in response to mitogenic stimuli, including extracellular signal regulated protein kinases Erk1 and Erk2. Rsk1 is activated by MAPK in vitro and in vivo via phosphorylation. Active Rsk's appear to play a major role in transcriptional regulation by translocating to the nucleus and phosphorylating c-Fos and CREB.
