c-Myc is a very potent oncogene upregulated in various types of cancer. c-Myc, through its role as a transcription factor, alters the expression of hundreds of target genes, often oncogenes or tumor suppressors. Clone 9E10 recognizes recombinant proteins that incorporate the c-Myc epitope tag and detects human c-Myc proteins and peptides in random coil rather than alpha-helix structures.
