abstract：:Immunoglobulin genes contain a conserved eight base sequence element 5' to the site of transcription initiation. This octamer can serve as a site for the binding of nuclear proteins which are presumably involved in the cell type specific expression of this family of genes. In studying the binding of nuclear proteins t...

abstract：:DNA double-strand breaks are repaired by end-joining or homologous recombination. A key-committing step of recombination is DNA end resection. In resection, phosphorylated CtIP first promotes the endonuclease of MRE11-RAD50-NBS1 (MRN). Subsequently, CtIP also stimulates the WRN/BLM-DNA2 pathway, coordinating thus both...
