'Gene bookmarking' is a mechanism of epigenetic memory that functions to transmit through mitosis the pattern of active genes and/or genes that can be activated to daughter cells. It is thought that, at a point before mitosis, genes that exist in an open, transcriptionally competent state are bound by proteins or marked by some kind of modification event. This is thought to facilitate the assembly of transcription complexes on the promoters in early G1, thereby ensuring that daughter cells have the same pattern of gene expression as the cell from which they derived. Little is known, however, about these 'bookmarking factors' and modifications or the mechanisms by which they mediate the transmission of transcriptional competence after mitosis is complete. Recent findings have provided new insights into the mechanisms, regulation and biological importance of gene bookmarking in eukaryotic cell function.
