我们证明了脂质磷酸酶相关蛋白(PLPPR)可以通过与RhoGDI相互作用来调节神经元的黏附和细胞骨架,RhoGDI调节RhoA和rac1 GTP酶。描述这些结果的论文已经发表。 PLPPR,像许多跨膜受体一样,在靠近膜的胞外位置被切割。我们现在已经证明,这种切割是通过一种类似呋喃的蛋白酶进行的。裂解释放出与其他跨膜分子相关联的原始受体片段。此外,我们还证明了这种分裂是可以调节的。进一步的实验将确定切割在调制信号转导中的确切作用。
英文摘要
We demonstrated the the Lipid Phosphate Phosphatase-Related Proteins (PLPPRs) can modulate neuronal adhesion and the cytoskeleton through interactions with RhoGDI that modulated both RhoA and Rac1 GTPases. Papers describing these results have been published. PLPPRs, like many transmembrane receptors, are cleaved at an extracellular site near the membrane. We have now demonstrated that this cleavage is through a furin-like protease. The cleavage releases a fragment of the original receptor that associates with other transmembrane molecules. In addition, we showed that this cleavage can be regulated. Further experiments will determine the exact role of cleavage in modulating signal transduction.
