Diacylglycerol kinase (DGK) is an enzyme that converts diacylglycerol (DG) to phosphatidic acid (PA). As both DG and PA serve as lipidic second messengers, DGK plays a pivotal role in controlling the balance of two signaling pathways mediated by DG and PA in cellular functions. DGKζ, one member of the mammalian DGK family, is reported to contain a nuclear localization signal, which suggests its functional role in the nucleus. Previously, morphological studies using tagged expression vectors and immunostaining of rat tissues or cells have revealed that DGKζ localizes mainly to the nucleus. However, a limited number of studies reported the detailed localization of native protein of DGKζ in human tissues and cells. In this study, we developed a novel anti-human DGKζ monoclonal antibody, DzMab-1, which is very advantageous in immunocytochemistry of human cultured cells.
