ターゲット情報

  • 機能

    Plasma membrane-associated small GTPase which cycles between an active GTP-bound and inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses, such as secretory processes, phagocytose of apoptotic cells and epithelial cell polarization. Augments the production of reactive oxygen species (ROS) by NADPH oxidase.

  • 組織特異性

    Hematopoietic specific.

  • 関連疾患

    Defects in RAC2 are the cause of neutrophil immunodeficiency syndrome (NEUID) [MIM:608203].

  • 配列類似性

    Belongs to the small GTPase superfamily. Rho family.

  • 細胞内局在

    Cytoplasm. Membrane-associated when activated.
  • Information by UniProt

  • 参照データベース

    • 製品の状態

      Rac2 has high sequence homology with other Rac proteins. Therefore some antibodies may show cross-reactivity.

    Question

    Dear Sir/Madam,

    I would like to buy a Rac2 antibody. I saw you sell 2 differents antibodies ab93614 and ab2244 and I would like to know the sequence of the epitop you used for their synthesis.

    Best regards,

    Answer

    Thank you for your inquiry.

    ab2244 has been produced against the synthetic peptide: PQPTRQQKRACSLL, corresponding to C terminal amino acids 179-192 of Human RAC2.

    ab93614 has been produced using a proprietary sequence peptide derived from inbetween amino acid 163 to 192 of theC-terminal region of humanRAC2. I am sorry that I can not provide the more detailled sequence, as it is proprietary information of our source of this antibody.

    I hope this information is helpful. Please donot hesitate to contact us again, shouldyou have any concern or further question.

    Question

    How specific is this antibody for RAC2? Has it been tested for cross-reactivity with RAC1 or RAC3?

    Read More
    Answer

    Thank you for your enquiry. This antibody has not been tested for cross-reactivity with RAC1 or RAC3. You can BLAST the sequence to check, but I didn't see any hits for RAC1 or RAC3. If you have any additional questions, please contact us again.

    Question

    I have a query re your Rac2 polyclonal antibody (ab2244). I would like to know whether this antibody is absolutely specific for Rac2 and whether it cross-reacts with the very similar proteins Rac1 and/or Rac3. For example, has it been tested for a lack of reactivity with purified fusion proteins of Rac1/ Rac3? I need a Rac2 antibody that is completely specific, so any reassurance you can give me would be much appreciated before I consider a purchase. Thank you very much, Regards

    Answer

    Thank you for your question. Our immunogen was PQPTRQQKRACSLL.Cross-reactivity tests have not been done against Rac1 or Rac3, and a BLAST search could only find a significant alignment with RAC2. I hope this information helps you,
