Our Abpromise guarantee covers the use of ab76389 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 1 µg/ml. Predicted molecular weight: 42 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA Use at an assay dependent concentration.

Titre using peptide based assay: 1/62500.


  • Function
    Negative regulator of B-cell activation. Down-regulates cell proliferation (in vitro). Promotes RAC1-dependent membrane ruffle formation and reorganization of the actin cytoskeleton. Regulates cell spreading and cell polarization. Stimulates HDAC1 activity. Regulates LYN activity by modulating its tyrosine phosphorylation.
  • Tissue specificity
    Detected in peripheral blood B-cells (at protein level). Detected in spleen, liver and peripheral blood.
  • Sequence similarities
    Contains 1 SAM (sterile alpha motif) domain.
    Contains 1 SH3 domain.
  • Cellular localization
    Nucleus. Cytoplasm. Cell projection > ruffle. Shuttles between cytoplasm and nucleus. Colocalizes with the actin cytoskeleton and actin-rich membrane ruffles.
