Target

  • Function

    Serine/threonine-protein kinase that acts downstream of ERK (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenic and stress-induced activation of transcription factors, regulates translation, and mediates cellular proliferation, survival, and differentiation. May function as tumor suppressor in epithelial ovarian cancer cells.
  • Tissue specificity

    Widely expressed with higher expression in lung, skeletal muscle, brain, uterus, ovary, thyroid and prostate.
  • Sequence similarities

    Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily.
    Contains 1 AGC-kinase C-terminal domain.
    Contains 2 protein kinase domains.
  • Post-translational
    modifications

    Activated by phosphorylation at Ser-218 by PDPK1. Autophosphorylated on Ser-377, as part of the activation process. May be phosphorylated at Thr-356 and Ser-360 by MAPK1/ERK2 and MAPK3/ERK1.
    N-terminal myristoylation results in an activated kinase in the absence of added growth factors.
  • Cellular localization

Images

  • Paraffin-embedded human lung cancer tissue stained for RSK3 with ab238332 at a 1/100 dilution in immunohistochemical analysis.

  • HeLa (human epithelial cell line from cervix adenocarcinoma) cells stained for RSK3 (Green) using ab238332 at a 1/66 dilution in ICC/IF.

    The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal goat serum. The cells were then incubated with the primary antibody overnight at 4°C. Secondary used is an Alexa-Fluor®488-conjugated Goat Anti-Rabbit IgG (H+L). Counterstained with DAPI.
