Target

  • Function

    Deubiquitinase involved in DNA damage response checkpoint and MYC proto-oncogene stability. Involved in DNA damage induced apoptosis by specifically deubiquitinating proteins of the DNA damage pathway such as CLSPN. Also involved in G2 DNA damage checkpoint, by deubiquitinating CLSPN, and preventing its degradation by the anaphase promoting complex/cyclosome (APC/C). In contrast, it does not deubiquitinate PLK1. Specifically deubiquitinates MYC in the nucleoplasm, leading to prevent MYC degradation by the proteasome: acts by specifically interacting with isoform 1 of FBXW7 (FBW7alpha) in the nucleoplasm and counteracting ubiquitination of MYC by the SCF(FBW7) complex. In contrast, it does not interact with isoform 4 of FBXW7 (FBW7gamma) in the nucleolus, allowing MYC degradation and explaining the selective MYC degradation in the nucleolus.

  • Sequence similarities

    Belongs to the peptidase C19 family. USP28 subfamily.
    Contains 1 UIM (ubiquitin-interacting motif) repeat.

  • Post-translational
    modifications

    Degradaded upon nickel ion level or hypoxia exposure.
    Phosphorylated upon DNA damage at Ser-67 and Ser-714, by ATM or ATR.

    Question

    I have a vial of this USP28 Ab (ab126604). Two specific questions: 1. Is this antibody tested for ELISA application? 2. What's the region of protein the antibody is recognizing (i.e. region of immunogen sequence)? I need to have an idea the recognition site may not be blocked by other antibodies.

    Answer

    The USP28 antibody ab126604 has not, to our knowledge, been tested in ELISA. It was raised against a sequence near the C terminus of the protein, between amino acids 120 - 160 of accession Q96RU2, http://www.uniprot.org/uniprot/Q96RU2.

    I would like to test the antibody Abcam ID: ab126604 (anti-USP28 antibodies) in pig tissues. Can you give me an abtrial discount code?
    thank you

    Answer

    Thank you for contacting us.

    The immunogen sequence alignment of ab126604 with Pig protein (http://www.uniprot.org/uniprot/F1SM65) is just 20% which means there are minimal changes that this antibody would cross react. I am sorry I am unable to offer you 100% Abtrial discount code.

    The following antibody immunogen show high similarity e.g. ab137438, ab70896 (http://www.ebi.ac.uk/Tools/services/web_clustalw2/toolresult.ebi?tool=clustalw2&jobId=clustalw2-I20130227-113829-0962-37379653-oy)

    I can provide Abtrial code for these ones if you are interested.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
