RSK1 in HeLa Human Cell Line. RSK1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human RSK1 Monoclonal Antibody (Catalog # MAB992) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

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.
