RSK1 in Human Ovarian Cancer Tissue. RSK1 was detected in immersion fixed paraffin-embedded sections of human ovarian cancer tissue using Human/Mouse/Rat RSK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF992) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rabbit HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS005) and counterstained with hematoxylin (blue).

Detection of Human/Mouse/Rat RSK1 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, HepG2 human hepatocellular carcinoma cell line, TS1 mouse helper T cell line, and PC‑12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 0.2 µg/mL of Human/Mouse/Rat RSK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF992) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for RSK1 at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

The 90 kDa ribosomal protein S6 kinases (RSK1-4) are a family of broadly expressed Ser/Thr kinases activated in response to mitogenic stimuli, including growth factors and tumor-promoting phorbol esters. RSKs are directly phosphorylated by ERK1 and ERK2, leading to RSK autophosphorylation and activation. Active RSKs appear to play a major role in transcriptional regulation by translocating to the nucleus and phosphorylating c-Fos and CREB.
