Function of the c-Myc oncoprotein

G J Kato et al. FASEB J. 1992 Sep.

Abstract

The c-Myc protein, the product of the c-myc proto-oncogene, is a nuclear phosphoprotein with DNA binding properties. Deregulated c-myc expression participates in the development of experimentally induced tumors, and its expression appears to be abnormal in many naturally occurring malignancies. Although the precise molecular mechanism of c-Myc activity in oncogenesis and in normal cell proliferation is unknown, recent advances have uncovered a series of molecular and cellular properties of c-Myc. These properties include nuclear localization, transcriptional activation, oligomerization nonspecific and specific DNA binding. Recently, the c-Myc protein was found to heterodimerize with Max, a protein that cooperates with c-Myc to bind specifically to a core DNA sequence, CAC(G/A)TG. These characteristics suggest that c-Myc participates in the regulation of gene transcription in normal and neoplastic cells.
