  • Immunogen

    Fusion protein. This information is considered to be commercially sensitive.

  • General notes

    This antibody clone is manufactured by Abcam.

     

    The GAL4 Activation Domain monoclonal antibody binds specifically to the AD of the yeast GAL4 protein. This antibody is useful for verifying the expression and correct molecular weight of fusion proteins containing GAL4 AD as the fusion partner in two hybrid studies. The activation domain is typically used in a two-hybrid experiment as the fusion partner for a library of cDNA clones to screen against a protein of interest fused to a DNA-binding domain. Gal4is a positive regulator for the gene expression of the galactose-induced genes such as GAL1, GAL2, GAL7, GAL10, and MEL1 which encode for the enzymes used to convert galactose to glucose. It recognizes a 17 base pair sequence in (5'-CGGRNNRCYNYNCNCCG-3') the upstream activating sequence (UAS-G) of these genes.

    Product was previously marketed under the MitoSciences sub-brand.

Target

  • Relevance

    Function: This protein is a positive regulator for the gene expression of the galactose-induced genes such as GAL1, GAL2, GAL7, GAL10, and MEL1 which encode for the enzymes used to convert galactose to glucose. It recognizes a 17 base pair sequence in (5'-CGGRNNRCYNYNCNCCG-3') the upstream activating sequence (UAS-G) of these genes. Subunit structure: Binds DNA as a homodimer. Interacts directly with the mediator subunits GAL11/MED15 and SRB4/MED17. Domain: The 9aaTAD motif (residues 862 to 870) is a transactivation domain present in a large number of yeast and animal transcription factors. Post-translational modification: Association between GAL11 and GAL4 may serve to expedite phosphorylation of GAL4.

    Answer

    Thank you for your email.

    We scientific support team at Abcam have years of experience in laboratory as part of our PhDs and research projects. We do not make fun of our customers as we know how it feels when research gets stuck just due to a faulty or wrong product so we try to be very lenient with customers in order to help them, in their research.

    As of ab1396 datasheet we list predicted species on datasheets if the proteins show 80-90% homology. Although the GAL4 protein is not expressed in Drosophila however because similar UAS-GAL4 expression system is present in drosophila and if the same S.cereveisiae fragment is expressed then why the antibody shouldn't cross react. This was the idea of keeping Drosophila as predicted species, which I have removed now.

    I am happy to replace this antibody with ab9110. Could you send me the purchase order number of ab1396?

    Many thanks for your cooperation in this case. I will look forward to hearing from you soon.

    Answer

    Thank you very much for your patience.

    I had requested a retest of this antibody with the wild type and transfected cell lysates we have. I can confirm that the antibody (ab1396, ab135397 and ab135398) is specific to the target and does not bind to control wild type cell line (no insert). The lysates are same as of ab135398.

    Please find attached the results.

    I hope these results will helpful to retest the wild type cell line you are using. Please do not hesitate to contact me with any further question.
