  • General notes


    RAC, Cdc 42 and Rho A, B, and C are members of a small RhoGTPase family that bind and hydrolyze GTP. GTP bound RAC 1 and cdc 42 play a pivotal role in controlling cell shape, adhesion, growth and transformation. Active Rac 1 is implicated in regulating serum response element (SRE), NFAT 1 and nuclear factor kappa B (NF kappa B) transcription activities. Activated RAC 1 and Cdc 42 bind and activate PAK 1, which in turn activates key downstream signaling proteins including MEKK 1 and JNK. RAC 1 and Cdc 42 are phosphorylated on serine 71, a putative Akt site located between the protein binding domain and GTP binding domain. Phosphorylation of RAC 1 on serine 71 regulates its GTP binding and GTPase activity.

Properties

  • FormLiquid
  • Storage instructionsShipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
  • Storage bufferPreservative: 0.05% Sodium Azide
    Constituents: 50% Glycerol, PBS, 1mg/ml BSA (IgG, protease free). pH 7.3
  • Concentration information loading...
  • PurityImmunogen affinity purified
  • Purification notesThe antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated RAC 1. The final product is generated by affinity chromatography using a RAC 1 derived peptide that is phosphorylated at serine 71.

Target

  • RelevanceCdc42/Rac belongs to the superfamily of small GTPases that are structurally linked to the proto-oncogene product p21ras and are important for the control of cell growth and differentiation as well as for intracellular organization. Cdc42/Rac is an important upstream regulator of the protein kinase cascade that controls the SAPK/JNK and p38 activity. Recent data also suggest that constitutive active forms of Cdc42 can induce apoptosis through a mechanism requiring signaling through SAPK/JNK.

  • Peptide Competition and Phosphatase Treatment:
    Lysates prepared from A431 cells left unstimulated (1) or stimulated with EGF (2-6) were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were either not treated (1-5) or treated with lambda phosphatase (6), blocked with a 5% BSA-TBST buffer for one hour at room temperature, and incubated with ab5482 antibody for two hours at room temperature in a 3% BSATBST buffer, following prior incubation with: no peptide (1, 2, 6), the nonphosphopeptide corresponding to the immunogen (3), a generic phosphoserine containing peptide (4), or, the phosphopeptide immunogen (5), After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG HRP conjugate and bands were detected using the Pierce SuperSignal method. The data show that the peptide corresponding to ab5482 blocks the antibody signal. The data also shows that phosphatase stripping eliminates the signal, verifying that the antibody is phospho-specific.

The antibody concentration of the lot you have is 0.35 mg/ml.

This antibody recognizes a sequence that is exactly conserved amongst the proteins. We would thus expect that providing you resolve your gel in order to separate the two proteins, the antibody should recognise the two proteins separately.
