Target

  • Function

    Receptor for a number of inflammatory CC-chemokines including MIP-1-alpha, MIP-1-beta and RANTES and subsequently transduces a signal by increasing the intracellular calcium ion level. May play a role in the control of granulocytic lineage proliferation or differentiation. Acts as a coreceptor (CD4 being the primary receptor) for HIV-1 R5 isolates.

  • Tissue specificity

    Highly expressed in spleen, thymus, in the myeloid cell line THP-1, in the promyeloblastic cell line KG-1A and on CD4+ and CD8+ T-cells. Medium levels in peripheral blood leukocytes and in small intestine. Low levels in ovary and lung.

  • Involvement in disease

    Genetic variation in CCR5 is associated with suseptibility to diabetes mellitus insulin-dependent type 22 (IDDM22) [MIM:612522]. A multifactorial disorder of glucose homeostasis that is characterized by susceptibility to ketoacidosis in the absence of insulin therapy. Clinical fetaures are polydipsia, polyphagia and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels.

  • Sequence similarities

    Belongs to the G-protein coupled receptor 1 family.

  • Post-translational
    modifications

    Sulfated on at least 2 of the N-terminal tyrosines. Sulfation contributes to the efficiency of HIV-1 entry and is required for efficient binding of the chemokines, CCL3 and CCL4.
    O-glycosylated, but not N-glycosylated. Ser-6 appears to be the major site. Also sialylated glycans present which contribute to chemokine binding. Thr-16 and Ser-17 may also be glycosylated and, if so, with small moieties such as a T-antigen.
    Palmitoylation in the C-terminal is important for cell surface expression, and to a lesser extent, for HIV entry.
    Phosphorylation on serine residues in the C-terminal is stimulated by binding CC chemokines especially by APO-RANTES.

    Question

    Good day   I am a postdoctoral scientist at the NIH and I am interested in purchasing one of your CCR5 peptides. However I am not sure which of the peptide products (ab92719, ab95861 or ab7876) might be more suited to my experiment.   I am working on anti-HIV targets and I want to test (via ELISAs) if my target inhibits the gp120-CCR5 binding. Could you recommend one of your CCR5 peptides (and corresponding anti-CCR5 antibody) that might be most suited for my application?   Thanks and regards

    Answer

    Thank you for contacting Abcam.



    These peptides are very short fragments of the CCR5 protein and as such may not contain the gp120 binding site. You may wish to use the whole protein. While this is not currently available at Abcam, you may find this by searching biocompare.com These peptides (ab7876ab92719 and ab95861) are the immunizing antigens for antibodies ab7346, ab64620 and ab85837 respectively.



    None of the antibodies has yet been tested in ELISA. For UNTESTED species and/or applications, we have established a testing discount program. Here is a brief description of how it works:

    The testing discount program is for customers who like to use an antibody/protein on an untested species/application. You would purchase the antibody at full price, test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount for ONE antibody at the full price (100%) of the antibody you have tested. The terms and conditions applicable to this offer can be found here: https://www.abcam.com/collaborationdiscount.



    If you would be interested in this offer please let me know.

    Answer

    Thank you for your enquiry. For ab2001 and ab7346, the peptides are non-HPLC, which averages out to 60-70% purity. Ab2001 (the antibody) was immunoaffinity chromatography purified IgG, and ab7346 (CCR5 antibody) is purified IgG. I will have to get back to you regarding the other peptides. If you have any additional questions, please let us know.

    Question

    DESCRIPTION OF THE PROBLEM Multiple bands DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes ADDITIONAL NOTES Can you send a pic of a WB indicating the correct size and location of the CCR5 band (s)?

    Read More
    Answer

    We unfortunately do not have a picture of a Western to share, but the expected band size using ab7346 is approximately 40 kDa. To get rid of the non-specific bands on your blot, I suggest decreasing the concentrations of the primary and secondary and also make sure that you run a no primary control. If you have any more questions, please contact us again.
