title: Histone H1: Lessons from Drosophila.
abstract: Eukaryotic genomes are structured in the form of chromatin with the help of a set of five small basic proteins, the histones. Four of them are highly conserved through evolution, form the basic unit of the chromatin, the nucleosome, and have been intensively studied and are well characterized. The fifth histone, histone H1, adds to this basic structure through its interaction at the entry/exit site of DNA in the nucleosome and makes an essential contribution to the higher order folding of the chromatin fiber. Histone H1 is the less conserved histone and the less known of them. Though for long time considered as a general repressor of gene expression, recent studies in Drosophila have rejected this view and have contributed to uncover important functions on genome stability and development. Here we present some of the most recent data obtained in the Drosophila model system and discuss how the lessons learnt in these studies compare and could be applied to all other eukaryotes.
