Histone chaperone regulates replication
F orm follows physics in the fl y eye, say The idea that a small set of physical forces governs the shape of tissues goes back at least a hundred years, but there has been little evidence to support it. Now, Hilgenfeldt et al. show that just two parameters— cell elasticity and adhesion strength—can account for the arrangement of cells in the ommatidium, the 20-cell subunit of the fl y's compoun...
متن کاملHistone chaperone Chz1p regulates H2B ubiquitination and subtelomeric anti-silencing
Chz1p is a histone chaperone that interacts physically and functionally with the histone variant Htz1p, which has been implicated in establishing and maintaining boundaries between transcriptionally inactive heterochromatin and active euchromatin. To investigate the role of Chz1p in chromatin organization, we performed genome-wide expression arrays and chromatin immunoprecipitations of SIR comp...
متن کاملHistone chaperone APLF regulates induction of pluripotency in murine fibroblasts.
Induction of pluripotency in differentiated cells through the exogenous expression of the transcription factors Oct4, Sox2, Klf4 and cellular Myc involves reprogramming at the epigenetic level. Histones and their metabolism governed by histone chaperones constitute an important regulator of epigenetic control. We hypothesized that histone chaperones facilitate or inhibit the course of reprogram...
متن کاملTwo surfaces on the histone chaperone Rtt106 mediate histone binding, replication, and silencing.
The histone chaperone Rtt106 binds histone H3 acetylated at lysine 56 (H3K56ac) and facilitates nucleosome assembly during several molecular processes. Both the structural basis of this modification-specific recognition and how this recognition informs Rtt106 function are presently unclear. Guided by our crystal structure of Rtt106, we identified two regions on its double-pleckstrin homology do...
متن کاملThe co-chaperone BAG3 regulates Herpes Simplex Virus replication.
Viruses as obligate intracellular parasites use host cell proteins to ensure efficient replication and spread. Cellular proteins are required for several stages of a virus life cycle. Here, we identify BAG3, a co-chaperone, as a regulator of herpes virus immediate early gene expression. We report that a herpes simplex virus lacking the gene encoding a potent transcriptional activator, ICP0, is ...
