Multiple functions of MRN in end-joining pathways during isotype class switching.

abstract：:The ISWI family of ATP-dependent chromatin remodelers represses transcription by changing nucleosome positions. ISWI regulates nucleosome positioning by requiring a minimal length of extranucleosomal DNA for moving nucleosomes. ISW2 from Saccharomyces cerevisiae, a member of the ISWI family, has a conserved domain cal...
