Myb binding proteins: regulators and cohorts in transformation.

The c-Myb and v-Myb proteins are transcription factors that regulate cell proliferation and differentiation. Both Myb proteins have been shown to interact with a number of cellular proteins, some of which are transcription factors that cooperate to activate specific promoters, while others regulate the transcriptional activity of Myb in specific contexts. By comparing and analysing the types of proteins that bind Myb, and the conserved domains of Myb that interact with other proteins, conclusions can be drawn regarding the role of specific partner proteins in the regulation of gene expression, cell proliferation and disease.
