Description_x000D_ General description_x000D_ MYC (MYC proto-oncogene) is a transcriptional factor and oncoprotein. c-myc is a member of MYC gene family. It is located on human chromosome 8q24. c-Myc gene codes for basic helix-loop-helix/leucine zipper (bHLH/LZ) transcription factor._x000D_ The cellular myelocytomatosis (c-myc) is the cellular homologue of the v-myc gene originally isolated from an avian myelocytomatosis virus. The gene encoding it is mapped to human chromosome 8q24. It is a member of MYC gene family. c-Myc gene codes for basic helix-loop-helix/leucine zipper (bHLH/LZ) transcription factor that regulates the G1-S cell cycle transition._x000D_ Immunogen_x000D_ v-myc avian myelocytomatosis viral oncogene homolog_x000D_ Application_x000D_ All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry._x000D_ The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

LLC_x000D_ Biochem/physiol Actions_x000D_ MYC (MYC proto-oncogene) may be essential for cancer initiation, promotion and therapy resistance._x000D_ The cellular myelocytomatosis (c-myc) oncogene has a crucial role in cellular proliferation, differentiation, apoptosis and acts as transcriptional regulator of gene expression. c-myc expression is essential and sufficient to assist most of the cells to enter DNA synthetic (S) phase of the cell cycle. The encoded protein plays a crucial role in vasculogenesis and angiogenesis during cancer development and progression. c-myc interacts with its binding partner Max and activates the transcription of growth promoting genes such as cyclin D2 and ornithine decarboxylase. It also represses the transcription of multiple genes, especially p21 and p27, by binding to the transcription initiator element (Inr) in a complex with Max and either Sp1 or Miz1. Overexpression of MYC in DLBCL (diffuse large B-cell lymphoma) results in poor outcome and invasive treatment when medicated with rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP)._x000D_ Features and Benefits_x000D_ Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section._x000D_ Every Prestige Antibody is tested in the following ways:_x000D_ • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues._x000D_ • Protein array of 364 human recombinant protein fragments._x000D_ • Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)_x000D_ Linkage_x000D_ Corresponding Antigen APREST88670.
