Characterization of DNA-PK-Bound End Fragments Using GLASS-ChIP.” Methods Mol Biol, 2444, Pp. 171-182. Abstract. “
Endonucleolytic cleavage of DNA ends by the human Mre11-Rad50-Nbs1 (MRN) complex occurs in a manner that is promoted by DNA-dependent protein kinase (DNA-PK). A method is described to isolate DNA-PK-bound fragments released from chromatin in human cells using a modified Gentle Lysis and Size Selection chromatin immunoprecipitation (GLASS-ChIP) protocol. This method, combined with real-time PCR or next-generation sequencing, can identify sites of MRN endonucleolytic cutting adjacent to DNA-PK binding sites in human cells.
