Protocol for sleep analysis in the brain of genetically modified adult mice

Elucidating the molecular pathways that regulate animal behavior such as sleep is essential for understanding how the brain works. However, to examine how a certain functional domain of protein is involved in animal behavior is challenging. Here, we present a protocol for inducing endogenous protein that lacks a specific functional domain using Cre-mediated allele modification in neurons followed by electroencephalogram/electromyogram (EEG/EMG) recording to study the role of kinases in sleep. This strategy is applicable to other gene targets or behaviors. For complete details on the use and execution of this protocol, please refer to Iwasaki et al. (2021).
