Comments
Of the four diacylglycerol kinases (DGK) isozymes found in the nucleus, DGKζ is the only one to contain a nuclear localization signal. DGKζ regulates nuclear diacylglycerol levels as well as cell cycle progression from G1 to S phase through decreased phosphorylation of retinoblastoma protein (pRb). Impaired nuclear export of DGKζ increased cell cycle arrent in C2C12 cells. It has also been speculated that the absence of the COOH-terminus of DGKζ enhance its interactions with CRM1.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
