Abstract

The study will focus on several important issues that remain to be resolved in relation to the binding of HMG1,2 to DNA and chromatin. The main emphasis will be on the distinguishing features of HMG1 and 2, viz. tandem HMG boxes and a long acidic tail. Particular aspects include: the nature of the cooperative binding of tandem HMG boxes to be the highest- affinity DNA substrate (minicircles); how tandem HMG boxes bind to linear DNA; how (whether) the acidic tail interacts with the rest of the protein (HMG boxes, linkers); and how the tandem HMG boxes and the acidic tail are involved in chromatic binding. We will also assess the importance of the two acetylatable lysine residues in the N-terminal strand of the A domain of the HMG1 for DNA binding.
