Application Abreviews Notes
IHC-P Use at an assay dependent concentration.
ICC 1/100 - 1/250.
Flow Cyt 1/20.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

WB 1/1000 - 1/5000. Detects a band of approximately 200 kDa (predicted molecular weight: 182 kDa).
  • Application notesIs unsuitable for IP.
  • Target

    • FunctionComponent of a protein kinase signal transduction cascade. Activates the CSBP2, P38 and JNK MAPK pathways, but not the ERK pathway. Specifically phosphorylates and activates MAP2K4 and MAP2K6.
    • Tissue specificityExpressed at high levels in heart, placenta, skeletal muscle and pancreas, and at lower levels in other tissues.
    • Sequence similaritiesBelongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily.
      Contains 1 protein kinase domain.
    • Cellular localizationCytoplasm > perinuclear region. Localized in perinuclear vesicular-like structures, probably Golgi-associated vesicles.
