Our Abpromise guarantee covers the use of ab85723 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 1/2000 - 1/10000. Predicted molecular weight: 225 kDa.
IP Use at 3-5 µg/mg of lysate.
IHC-P 1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • Function

    Involved in regulation of adherens junction between cells. Functions as a guanine nucleotide exchange factor (GEF), which activates Rap1 small GTPase by exchanging bound GDP for free GTP.
  • Tissue specificity

    Widely expressed at low level. Highly expressed in skeletal muscle, prostate and ovary.
  • Sequence similarities

    Belongs to the DOCK family.
    Contains 1 DHR-1 (CZH-1) domain.
    Contains 1 DHR-2 (CZH-2) domain.
    Contains 1 SH3 domain.
  • Domain

    The DHR-2 domain probably mediates the GEF activity.
  • Cellular localization

    Endomembrane system.
  • Information by UniProt
  • Database links

  • Alternative names

    • Dedicator of cytokinesis protein 4 antibody
    • Dock4 antibody
    • DOCK4_HUMAN antibody
    • KIAA0716 antibody
