脂质衍生的磷酸肌醇(insitol phosphate, InsPs)由六类InsP激酶(通常称为ipk)的作用产生的第二信使家族组成。遗传研究表明,InsPs在胚胎发育中起着关键作用,但其在哺乳动物细胞功能中的作用机制在很大程度上尚不清楚。本章概述了通过组成活性G蛋白和各种ipk的共表达来操纵细胞InsP谱的方法。它提供了一种上调多种InsPs代谢的机制,从而能够评估这些InsPs对细胞功能的影响。
Lipid-derived inositol phosphates (InsPs) comprise a family of second messengers that arise through the action of six classes of InsP kinases, generally referred to as IPKs. Genetic studies have indicated that InsPs play critical roles in embryonic development, but the mechanisms of action for InsPs in mammalian cellular function are largely unknown. This chapter outlines a method for manipulating cellular InsP profiles through the coexpression of a constitutively active G protein and various IPKs. It provides a mechanism by which the metabolism of a variety of InsPs can be upregulated, enabling the evaluation of the effects of these InsPs on cellular functions.
