Detection of Mouse Phospho-RSK3 (S218) by Western Blot.
Western blot shows lysates of NIH‑3T3 mouse embryonic fibroblast cell line untreated (-) or treated (+) with 100 ng/mL Human PDGF (Catalog # 120-HD) for for the indicated times. PVDF membrane was probed with 0.5 µg/mL of Rabbit Anti-Human/Mouse Phospho-RSK3 (S218) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF893), followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-RSK3 (S218) 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.
