Disease

[PLCE1_HUMAN] Familial idiopathic steroid-resistant nephrotic syndrome with diffuse mesangial sclerosis;Familial idiopathic steroid-resistant nephrotic syndrome with focal segmental hyalinosis. The disease is caused by mutations affecting the gene represented in this entry.

Function

[PLCE1_HUMAN] The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes. PLCE1 is a bifunctional enzyme which also regulates small GTPases of the Ras superfamily through its Ras guanine-exchange factor (RasGEF) activity. As an effector of heterotrimeric and small G-protein, it may play a role in cell survival, cell growth, actin organization and T-cell activation.^{[1] [2] [3] [4] [5] [6] [7]}
