    Tyrosine kinase substrate p62DOK

    Signals from most growth factors and cytokines are transduced by receptor tyrosine kinases or non-receptortyrosine kinases. Activated tyrosine kinases phosphorylatetheir substrates, which mediate the cellular response to extracellular stimuli. A long-sought major substrate termed p62dok (downstream of tyrosine kinase) for many tyrosine kinases including c-kit, v-abl, v-Fps, v-Src, v-Fms, and activated EGF, PDGF, IGF, VEGF and insulin receptors was identified recently from human and mouse by several laboratories. Upon phosphorylation, p62dok forms a complex with the ras GTPase-activating protein (RasGAP). p62dok represents a new family with very recently identified p56 dok.



Our Abpromise guarantee covers the use of ab8112 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.5 - 1 µg/ml. Detects a band of approximately 62 kDa.Can be blocked with Human DOK1 peptide (ab39756).
ICC/IF Use a concentration of 2 µg/ml.
IP Use at an assay dependent dilution. (see Abreview published on 27th July, 2006).


  • Function
    DOK proteins are enzymatically inert adaptor or scaffolding proteins. They provide a docking platform for the assembly of multimolecular signaling complexes. DOK1 appears to be a negative regulator of the insulin signaling pathway. Modulates integrin activation by competing with talin for the same binding site on ITGB3.
  • Tissue specificity
    Expressed in pancreas, heart, leukocyte and spleen. Expressed in both resting and activated peripheral blood T-cells.
  • Sequence similarities
    Belongs to the DOK family. Type A subfamily.
    Contains 1 IRS-type PTB domain.
    Contains 1 PH domain.
  • Domain
    The PTB domain mediates receptor interaction.
  • Post-translational
    Constitutively tyrosine-phosphorylated.
    Phosphorylated on tyrosine residues by the insulin receptor kinase. Results in the negative regulation of the insulin signaling pathway.
  • Cellular localization
    Cytoplasm and Cytoplasm > perinuclear region.
