Detection of Human Phospho-MSK1 (S212) by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line untreated (-) or treated (+) with 1 mM H2O2 for 1 hour or 300 mM sorbitol for 30 minutes. PVDF membrane was probed with 0.2 µg/mL of Rabbit Anti-Human Phospho-MSK1 (S212) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1036), followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-MSK1 (S212) at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
MSK1 in Human Kidney Cancer Tissue. MSK1 phosphorylated at S212 was detected in immersion fixed paraffin-embedded sections of human kidney cancer tissue using Rabbit Anti-Human Phospho-MSK1 (S212) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1036) at 15 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).

Mitogen- and stress-activated protein kinase 1 (MSK1), also known as ribosomal protein S6 kinase 5 (RPS6KA5), belongs to the AGC family of kinases. Both MSK1 and the related MSK2, also known as RSKB and RPS6KA4, have two kinase domains connected by a regulatory linker region, and are activated by the mitogen-activated protein kinases ERK1, ERK2, and p38. Nuclear MSK phosphorylates and activates a number of transcription factors, including ATF1 and CREB.
