Rsk-1 (p90-Rsk-1) is a member of a family of 90 kDa ribosomal protein S6 kinases, which includes Rsk-1, Rsk-2 and Rsk-3. These are broadly expressed serine/threonine protein kinases (1) activated in response to mitogenic stimuli, including extracellular signal-regulated protein kinases Erk1 and Erk2 (2). p90-Rsk-1 is activated by MAPK in vitro and in vivo via phosphorylation (3). Active Rsks appear to play a major role in transcriptional regulation by translocating to the nucleus and phosphorylating c-Fos and CREB (2,4).

|Immunohistochemical staining of untreated paraffin-embedded human cervical carcinoma using anti-Phospho-Rsk1 (pT359/pS363) RabMAb (cat. #2006-1).||Immunohistochemical staining of Phosphatase-treated paraffin-embedded human cervical carcinoma using anti-Phospho-Rsk1 (pT359/pS363) RabMAb (cat. #2006-1).||Western blot analysis on A431 cell lysate using anti- Phospho-Rsk1 (pT359/pS363) RabMAb (cat. #2006-1). Cell lysates were (1) untreated, or (2) treated with EGF.|
A synthetic phospho-peptide corresponding to residues surrounding Thr359 and Ser363 of human RSK1 was used as immunogen. The antibody only detects RSK1 phosphorylated on Threonine 359 and Serine 363.
