NanoDam is a technique for genome-wide profiling of the binding targets of any endogenously tagged chromatin-binding protein in vivo, without the need for antibodies, crosslinking, or immunoprecipitation. Here, we explain the procedure for NanoDam experiments in Drosophila, starting from a genetic cross, to the generation of sequencing libraries and, finally, bioinformatic analysis. This protocol can be readily adapted for use in other model systems after simple modifications. For complete details on the use and execution of this protocol, please refer to Tang et al. (2022).
