      Background InformationMyc proto-oncogene protein (UniProt: P01106; also known as Class E basic helix-loop-helix protein 39, bHLHe39, Proto-oncogene c-Myc, Transcription factor p64) is encoded by the MYC (also known as BHLHE39) gene (Gene ID: 4609) in human. c-Myc is a transcription factor that binds DNA in a non-specific manner, yet also specifically recognizes the core sequence 5'-CAC[GA]TG-3'. It regulates the expression of multiple genes involved in apoptosis, cell differentiation and cell proliferation. c-Myc is shown to be critically involved in the regulation of several growth promoting signaling pathways and is considered as an immediate early response gene that is downstream of many ligand-membrane receptor complexes. Its expression is reported to be tightly regulated by several transcriptional regulatory motifs within its proximal promoter region. Phosphorylation of c-Myc by serine/threonine kinase PIM2 at serine 329 is reported to lead to its stabilization. Active c-Myc is coupled to the MAX protein via its C-terminal helix-loop-helix leucine zipper (bHLHLZ) domain (aa 413-434) and this heterodimer interacts with a number of other transcription-related proteins. In normal cells its expression and function are regulated by developmental or mitogenic signals. c-Myc mRNA has a very short half-life and in the absence of positive regulatory signals there is a significant reduction in its transcription leading to low c-Myc protein levels that does not have any proliferative drive. However, in tumor cells its levels are increased either via mutations or induction via upstream oncogenic pathways. Serine 71 is shown to be phosphorylated by c-Jun kinase (JNK) that leads to induction of c-Myc induced apoptosis. Mutations leading to S71A/S81A are known to enhance transformation of cells and are shown to be more potent oncogenic mutants. It has been reported that the individual S71A and S81A mutants are not enough to promote increased transformation, but when combined they enhance transformation. Some mutations in c-Myc gene have been linked to B-cell chronic lymphocytic leukemia and Burkitt lymphoma. Over-expression of c-Myc has been reported in about 40% tumors.
