Chromatin remodeling factors and DNA replication.
Chromatin structures have to be precisely duplicated during DNA replication to maintain tissue-specific gene expression patterns and specialized domains, such as the centromeres. Chromatin remodeling factors are key components involved in this process and include histone chaperones, histone modifying enzymes and ATP-dependent chromatin remodeling complexes. Several of these factors interact dir...
متن کاملChromatin remodeling and initiation of DNA replication.
While much has been learned in recent years about the process of chromatin remodeling and its role in activation of transcription, relatively little has been reported on the role of chromatin remodeling in DNA replication. However, it is well established that transcription factors and chromatin structure play an important role in replication origin usage. Recent work has begun to indicate that ...
متن کاملFunction of the INO80 chromatin remodeling complex in DNA replication.
ATP-dependent chromatin remodeling complexes are involved in several nuclear processes. In particular the INO80 remodeling complex is an essential factor during transcription and DNA repair. Recently, several labs have described a novel role for INO80 during DNA replication. Moreover, Falbo et al. have presented evidence linking INO80's activities to the DNA damage tolerance pathways during rep...
متن کاملMaking of Viral Replication Organelles by Remodeling Interior Membranes
Positive-stranded RNA (+RNA) viruses exploit host cell machinery by subverting host proteins and membranes and altering cellular pathways during infection. To achieve robust replication, some +RNA viruses, such as poliovirus (PV), build special intracellular compartments, called viral replication organelles. A recent work from the Altan-Bonnett laboratory [1] gave new insights into the formatio...
متن کاملIno80 Chromatin Remodeling Complex Promotes Recovery of Stalled Replication Forks
BACKGROUND Chromatin remodeling complexes facilitate the access of enzymes that mediate transcription, replication or repair of DNA by modulating nucleosome position and/or composition. Ino80 is the DNA-dependent Snf2-like ATPase subunit of a complex whose nucleosome remodeling activity requires actin-related proteins, Arp4, Arp5 and Arp8, as well as two RuvB-like DNA helicase subunits. Budding...
