  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function

      Potential guanine nucleotide exchange factor (GEF). GEF proteins activate some small GTPases by exchanging bound GDP for free GTP.
    • Involvement in disease

      Defects in DOCK8 are the cause of hyperimmunoglobulin E recurrent infection syndrome autosomal recessive (AR-HIES) [MIM:243700]. It is a rare disorder of immunity characterized by immunodeficiency, recurrent infections, eczema, increased serum IgE, eosinophilia and lack of connective tissue and skeletal involvement.
    • Sequence similarities

      Belongs to the DOCK family.
      Contains 1 DHR-1 (CZH-1) domain.
      Contains 1 DHR-2 (CZH-2) domain.
    • Domain

      The DHR-2 domain may mediate some GEF activity.

    • Immunocytochemistry/Immunofluorescence analysis of Raji (human Burkitt's lymphoma) cells labelling DOCK8 with purified ab175208 at 1/500. Cells were fixed with 100% methanol. An Alexa Fluor® 488-conjugated goat anti-rabbit IgG (ab150077) at 1/1000 dilution was used as the secondary antibody. Nuclei couterstained with DAPI (blue).

      Secondary Only Control: PBS was used instead of the primary antibody as the negative control.

      Lane 1 : Raji cell lysate
      Lane 2 : THP1 cell lysate

      Lysates/proteins at 10 µg per lane.
