摘要
Recent observations suggest that diacylglycerol kinase (DGK) is one of the key enzymes involved in the regulation of signal transduction. It attenuates protein kinase C activity and cell cycle progression of T-lymphocytes, through controlling the intracellular levels of the second messengers, diacylglycerol and phosphatidic acid. To date, eight DGK isozymes containing characteristic zinc finger structures in common have been identified. Type I DGKs (alpha, beta and gamma) contain EF-hand motifs that contribute to the calcium-dependent activities of this type of DGK. A pleckstrin homology and/or an EPH C-terminal tail homology domains are found in type II isozymes (DGK delta and eta). DGK epsilon represents a third type of DGK that selectively phosphorylates arachidonate-containing diacylglycerol, DGK zeta (type IV) and DGK theta (type V) contain four tandem ankyrin repeats and a Ras-associating domain, respectively.
