Deletion of Prkcz Increases Intermittent Ethanol Consumption in Mice

Prkcz has been identified as a gene whose expression is positively correlated with ethanol (EtOH) consumption in mice and is also induced by EtOH. Two proteins are produced from Prkcz: protein kinase M zeta (PKMζ), which is expressed in the nervous system and protein kinase C zeta (PKCζ), which is expressed in other tissues. We examined Prkcz−/− mice that lack PKCζ and PKMζ to investigate
