| Research Abstract |
In this study, the physiological functions of lipid signaling molecule-producing enzymes, PIP5K and PLD, have been investigated. It was found that PIP5Kγ661 is dephosphorylated upon NMDA stimulation of hippocampal neurons, interacts with the adaptor complex AP-2 and stimulates the endocytosis of AMPA receptors, thereby inducing the long-term depression. On the other hand, PIP5Kα and PIP5Kβ were found to regulate spermatogenesis. Lastly, it was suggested that PLD is not involved in the neutrophil functions, such as superoxide generation and enzyme release, although the involvement of PLD in these neutrophil functions have been reported.
