The chromatin remodeling subunit Baf200 promotes normal hematopoiesis and inhibits leukemogenesis
BACKGROUND Adenosine triphosphate (ATP)-dependent chromatin remodeling SWI/SNF-like BAF and PBAF complexes have been implicated in the regulation of stem cell function and cancers. Several subunits of BAF or PBAF, including BRG1, BAF53a, BAF45a, BAF180, and BAF250a, are known to be involved in hematopoiesis. Baf200, a subunit of PBAF complex, plays a pivotal role in heart morphogenesis and coro...
متن کاملChromatin Remodeling, DNA Damage Repair and Aging
Cells are constantly exposed to a variety of environmental and endogenous conditions causing DNA damage, which is detected and repaired by conserved DNA repair pathways to maintain genomic integrity. Chromatin remodeling is critical in this process, as the organization of eukaryotic DNA into compact chromatin presents a natural barrier to all DNA-related events. Studies on human premature aging...
متن کاملSnapShot: Chromatin Remodeling Complexes
Unique subunits Swp82, Taf14, Snf6, Snf11 Rsc3,5,7,9, 10,30, Htl1, Ldb7, and Rtt102 INO80 regulates transcription and is involved in DNA repair and cellcycle checkpoint adaptation. It has ATP-dependent nucleosome mobilization activity in vitro. SWR1 regulates transcription and is also involved in deposition of histone H2AZ, chromosome stability, and cell-cycle checkpoint adaptation. In vitro it...
متن کاملISWI chromatin remodeling complexes in the DNA damage response
Regulation of chromatin structure is an essential component of the DNA damage response (DDR), which effectively preserves the integrity of DNA by a network of multiple DNA repair and associated signaling pathways. Within the DDR, chromatin is modified and remodeled to facilitate efficient DNA access, to control the activity of repair proteins and to mediate signaling. The mammalian ISWI family ...
متن کاملThe Human SRCAP Chromatin Remodeling Complex Promotes DNA-End Resection
BACKGROUND Repair of DNA double-strand breaks (DSBs) by homologous recombination requires 5'-3' resection of the DSB ends. In vertebrates, DSB resection is initiated by the collaborative action of CtIP and the MRE11-RAD50-NBS1 (MRN) complex. However, how this process occurs within the context of chromatin is still not well understood. RESULTS Here we identify the human SRCAP chromatin remodel...
