  • Function
    GTPase-activating protein for the ADP ribosylation factor family. May serve as a scaffold to bring together molecules to form signaling modules controlling vesicle trafficking, adhesion and cytoskeletal organization. Increases the speed of cell migration, as well as the size and rate of formation of protrusions, possibly by targeting PAK1 to adhesions and the leading edge of lamellipodia. Sequesters inactive non-tyrosine-phosphorylated paxillin in cytoplasmic complexes.
  • Sequence similarities
    Contains 3 ANK repeats.
    Contains 1 Arf-GAP domain.
  • Domain
    The paxillin-binding domain is masked in the full-length protein and is regulated by ARHGEF6.
  • Post-translational
    Phosphorylated on tyrosine residues by PTK2 and SRC in growing fibroblasts. Tyrosine-phosphorylation is increased following cell spreading on fibronectin, decreased in cells arrested in mitosis and increased in the ensuing G1 phase.
  • Cellular localization
    Cytoplasm. Cycles between at least 3 distinct intracellular compartments, including focal adhesions, cytoplasmic complexes and membrane protrusions. During cell migration, when cells detach, moves from the adhesions into the cytoplasmic complexes towards the leading edge, while, when cells adhere, it is found in vinculin-containing adhesions. Recruitment to adhesions may be mediated by active tyrosine-phosphorylated paxillin.

  • All lanes : Anti-GIT1 antibody (ab86235) at 0.04 µg/ml

    Lane 1 : Whole cell lysate from HeLa cells at 50 µg
    Lane 2 : Whole cell lysate from HeLa cells at 15 µg
    Lane 3 : Whole cell lysate from HeLa cells at 5 µg
    Lane 4 : Whole cell lysate from 293T cells at 50 µg

    Developed using the ECL technique.

    Predicted band size: 84 kDa
    Observed band size: 90 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 275 kDa, 56 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 3 minutes
  • Detection of GIT1 in Immunoprecipitates of Whole cell lysate from HeLa cells (1 mg for IP, 20% of IP loaded) using ab86235 at 3 µg/mg lysate for IP (Lane 1) and at 0.4 µg/ml for subsequent Western blot detection. Lane 2 represents control IgG IP. Detection: Chemiluminescence with an exposure time of 30 seconds.
