Our Abpromise guarantee covers the use of ab122701 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 1/250 - 1/500.
IHC-P 1/50 - 1/200. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC/IF Use a concentration of 1 - 4 µg/ml. The following steps are recommended prior to antibody incubation: cells fixation in ice cold 4% paraformaldehyde pH 7.2-7.3, followed by permeabilization with 0.1% Triton X-100 in PBS for 3x5 minutes.


  • Function
    Acts as guanine nucleotide exchange factor (GEF) for RHOA, RAC1 and CDC42 GTPases. Regulates cell migration and adhesion assembly and disassembly through a RAC1, PI3K, RHOA and AKT1-dependent mechanism. Increases both RAC1 and CDC42 activity, but decreases the amount of active RHOA. Required for MMP9 up-regulation via the JNK signaling pathway in colorectal tumor cells. Involved in tumor angiogenesis and may play a role in intestinal adenoma formation and tumor progression.
  • Tissue specificity
    Expressed at high levels in the placenta, spleen and kidney, at moderate levels in lung, small intestine, liver, brain and heart, and at low levels in skeletal muscle. Expression is aberrantly enhanced in most colorectal tumors.
  • Sequence similarities
    Contains 1 DH (DBL-homology) domain.
    Contains 1 PH domain.
    Contains 1 SH3 domain.
  • Domain
    The C-terminal tail is required for its GEF activity.
  • Cellular localization
    Cytoplasm. Cell projection > filopodium. Cell projection > lamellipodium. Cell projection > ruffle membrane. Accumulates in the lamellipodium and ruffle membrane in response to hepatocyte growth factor (HGF) treatment.
