内容記述 | Growth cone motility and morphology, which are critical for axon guidance, are controlled through intracellular events such as actin cytoskeletal reorganization and vesicular trafficking. The membrane phospholipid phosphatidylinositol 4,5-bisphosphate [PI(4,5)P2] has been implicated in regulation of these cellular processes in a diverse range of cell types. The main kinases involved in the production of PI(4,5)P2 are the type I phosphatidylinositol 4-phosphate 5-kinase (PIP5K) family, which consist of three isozymes, α, β and γ. Here, we demonstrate the involvement of PIP5Kβ in growth cone dynamics. Overexpression of a lipid kinase-deficient mutant of PIP5Kβ (PIP5Kβ-KD) in mouse dorsal root ganglion (DRG) neurons stimulated axon elongation and increased growth cone size, whereas wild-type PIP5Kβ tended to show opposite effects. Furthermore, PIP5Kβ-KD inhibited growth cone collapse of DRG neurons induced by semaphorin 3A (Sema3A). These results provide evidence that PIP5Kβ negatively regulates axon elongation and growth cone size and is involved in the cellular signaling pathway for Sema3A-triggered repulsion in DRG neurons. | |||||
