功能概要

通过将第二信使肌醇 1,4,5-三磷酸磷酸化为 Ins (1,3,4,5) P4 来调节肌醇磷酸代谢。肌醇 1,4,5-三磷酸 3-激酶的活性负责调节大量在细胞信号传导中很重要的肌醇多磷酸盐的水平。钙/钙调蛋白和蛋白质磷酸化机制均控制其活性。它也是环 AMP 依赖性蛋白激酶、钙/钙调蛋白依赖性蛋白激酶 II 和体外蛋白激酶 C 的底物。[RefSeq 提供,2011 年 4 月]

Regulates inositol phosphate metabolism by phosphorylation of second messenger inositol 1,4,5-trisphosphate to Ins(1,3,4,5)P4. The activity of the inositol 1,4,5-trisphosphate 3-kinase is responsible for regulating the levels of a large number of inositol polyphosphates that are important in cellular signaling. Both calcium/Calmodulin and protein phosphorylation mechanisms control its activity. It is also a substrate for the cyclic AMP-dependent protein kinase, calcium/calmodulin- dependent protein kinase II, and protein kinase C in vitro.[provided by RefSeq, Apr 2011]
