Target

  • FunctionPlasma membrane-associated small GTPase which cycles between an active GTP-bound and an inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses. Involved in epithelial cell polarization processes. Causes the formation of thin, actin-rich surface projections called filopodia.
  • Sequence similaritiesBelongs to the small GTPase superfamily. Rho family. CDC42 subfamily.
  • Post-translational
    modifications
    AMPylation at Tyr-32 and Thr-35 are mediated by bacterial enzymes in case of infection by H.somnus and V.parahaemolyticus, respectively. AMPylation occurs in the effector region and leads to inactivation of the GTPase activity by preventing the interaction with downstream effectors, thereby inhibiting actin assembly in infected cells. It is unclear whether some human enzyme mediates AMPylation; FICD has such ability in vitro but additional experiments remain to be done to confirm results in vivo.

    Lanes 1 - 4: Merged signal (red and green). Green - ab41429 observed at 20 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab41429 was shown to specifically react with CDC42 when CDC42 knockout samples were used. Wild-type and CDC42 knockout samples were subjected to SDS-PAGE. ab41429 and ab181602 (loading control to GAPDH) were diluted at 1/125 and 1/10 000 respectively and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

  • ab41429 staining CDC42 in SH-SY5Y cells by Immunocytochemistry/ Immunofluorescence.
    SH-SY5Y cells were differentiated 6 days with 10 µM retinoic acid and fixed with 4% paraformaldehyde in PBS. After 5 minutes incubation with ice-cold methanol the cells were washed twice with PBS and blocked with 10% normal donkey serum for 30 minutes. Incubation with primary antibody was performed over night at 4°C. After three-times washing with PBS, 1 hour incubation with the labeled Cy3 secondary antibody at 37°C the cells were mounted with DABCO/Mowiol.

ab41429 does not detect RhoA, we have tested this directly using recombinant RhoA protein versus recombinant CDC42 protein. However, we have not tested reactivity to Rac1 and therefore, we cannot comment on the cross-reactivity with Rac1 since the epit...
