title: Histone chaperones: modulators of chromatin marks.
abstract: The many factors that control chromatin biology play key roles in essential nuclear functions like transcription, DNA damage response and repair, recombination, and replication and are critical for proper cell-cycle progression, stem cell renewal, differentiation, and development. These players belong to four broad classes: histone modifiers, chromatin remodelers, histone variants, and histone chaperones. A large number of studies have established the existence of an intricate functional crosstalk between the different factors, not only within a single class but also between different classes. In light of this, while many recent reviews have focused on structure and functions of histone chaperones, the current text highlights novel and striking links that have been established between these proteins and posttranslational modifications of histones and discusses the functional consequences of this crosstalk. These findings feed a current hot question of how cell memory may be maintained through epigenetic mechanisms involving histone chaperones.
