摘要: The Myb domain is a highly conserved 50 amino acid motif found in all eukaryotes and often tandem repeats within single protein. DNA binding proteins with three such (3R) are present animals, plants, fungi protists. Invertebrate animals have 3R myb gene, whereas vertebrates studied thus far at least genes. genes of arose by two duplications from B-myb/Dm-myb-like ancestral gene. first duplication appears to resulted neomorphic paralogue central transactivation domain. This new gene then duplicated again give rise A-myb c-myb. An examination wide variety more distantly related domain-containing suggests that the most function may be interaction chromatin rather than DNA.
