  • FunctionLocation-regulated scaffold connecting MEK to RAF. Blocks MAP3K8 kinase activity and MAP3K8-mediated signaling. Acts as a negative regulator of MAP3K3-mediated activation of ERK, JNK and NF-kappa-B pathways, inhibiting MAP3K3-mediated interleukin-8 production.
  • Tissue specificityMainly expressed in brain and kidney.
  • Sequence similaritiesBelongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family.
    Contains 1 phorbol-ester/DAG-type zinc finger.
    Contains 1 protein kinase domain.
  • DomainThe protein kinase domain is predicted to be catalytically inactive.
  • Post-translational
    Phosphorylated on Ser-474 by MARK3.
  • Cellular localizationCytoplasm. Membrane.

  • Immunofluorescence analysis of KSR2 in HeLa cells, using ab72753 at 1/500 dilution. Right panel was also treated with immunising peptide.
  • KSR2 was immunoprecipitated using 0.5mg Hek293 whole cell extract, 5µg of Rabbit polyclonal to KSR2 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Hek293 whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab72753.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 108kDa; KSR2
