Overview

  • Product nameAnti-c-Myc (phospho Y74) antibody
    See all c-Myc primary antibodies
  • Description
    Rabbit polyclonal to c-Myc (phospho Y74)
  • SpecificityPreliminary results indicate that ab46848 specifically detects c-Myc phospho Y74 when its phosphorylation is over-expressed. There is no evidence that it detects the modification at endogenous levels.
  • Tested applicationsSuitable for: WBmore details
  • Species reactivity
    Reacts with: Human
  • Immunogen

    Synthetic peptide conjugated to KLH derived from within residues 50 - 150 of Human c-Myc, phosphorylated at Y74.

  • Positive control
    • This antibody gave a positive result in Hela Irradiated (5Gy) whole cell lysate.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 41 kDa (predicted molecular weight: 49 kDa).

Target

  • FunctionParticipates in the regulation of gene transcription. Binds DNA in a non-specific manner, yet also specifically recognizes the core sequence 5'-CAC[GA]TG-3'. Seems to activate the transcription of growth-related genes.
  • Involvement in diseaseNote=Overexpression of MYC is implicated in the etiology of a variety of hematopoietic tumors.
    Note=A chromosomal aberration involving MYC may be a cause of a form of B-cell chronic lymphocytic leukemia. Translocation t(8;12)(q24;q22) with BTG1.
    Defects in MYC are a cause of Burkitt lymphoma (BL) [MIM:113970]. A form of undifferentiated malignant lymphoma commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. Note=Chromosomal aberrations involving MYC are usually found in Burkitt lymphoma. Translocations t(8;14), t(8;22) or t(2;8) which juxtapose MYC to one of the heavy or light chain immunoglobulin gene loci.
  • Sequence similaritiesContains 1 basic helix-loop-helix (bHLH) domain.
  • Post-translational
    modifications
    Phosphorylated by PRKDC. Phosphorylation at Thr-58 and Ser-62 by GSK3 is required for ubiquitination and degradation by the proteasome. Phosphorylation at Ser-329 by PIM2 leads to the stabilization of MYC (By similarity). Phosphorylation at Ser-62 by CDK2 prevents Ras-induced senescence.
    Ubiquitinated by the SCF(FBXW7) complex when phosphorylated at Thr-58 and Ser-62, leading to its degradation by the proteasome. In the nucleoplasm, ubiquitination is counteracted by USP28, which interacts with isoform 1 of FBXW7 (FBW7alpha), leading to its deubiquitination and preventing degradation. In the nucleolus, however, ubiquitination is not counteracted by USP28, due to the lack of interaction between isoform 4 of FBXW7 (FBW7gamma) and USP28, explaining the selective MYC degradation in the nucleolus. Also polyubiquitinated by the DCX(TRUSS) complex.

  • Anti-c-Myc (phospho Y74) antibody (ab46848) at 1 µg/ml + HeLa Whole Cell Lysate - Irradiated (5Gy) at 10 µg

    Secondary
    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Performed under reducing conditions.

    Predicted band size : 49 kDa
    Observed band size : 41 kDa (why is the actual band size different from the predicted?)


    Exposure time : 20 minutes
  • IHC image of c-Myc staining in human breast carcinoma FFPE section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab46848, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
