Target

  • Function

    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.
  • Tissue specificity

    Hematopoietic specific.
  • Involvement in disease

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

    Belongs to the small GTPase superfamily. Rho family.
  • Cellular localization

    Cytoplasm. Membrane-associated when activated.
  • Target information above from: UniProt accession P15153 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010
    Nucleic Acids Res. 38:D142-D148 (2010) .

    Asked on Feb 08 2012

    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

    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
