General description

N-20:4 L-Serine (ARA-S), a unique lipoamino acid is endogenous in nature. It is localized to the brain. It has structural resemblance with anandamide, an endocannabinoid.

Biochem/physiol Actions

N-20:4 L-Serine (ARA-S) is a signaling lipid that regulates neuronal-type Ca2+ channels in the brain. ARA-S is known to produce endothelium-dependent arterial vasodilatation in vitro. It is also found to exert neuroprotective action following brain injury.

Traumatic brain injury (TBI) represents the leading cause of death in young individuals. It triggers the accumulation of harmful mediators, leading to secondary damage, yet protective mechanisms are also set in motion. The endocannabinoid (eCB) system consists of ligands, such

The novel endocannabinoid-like lipid N-arachidonoyl L-serine (ARA-S) causes vasodilation through both endothelium-dependent and -independent mechanisms. We have analyzed the vasorelaxant effect of ARA-S in isolated vascular preparations and its effects on Ca(2+)-activated K(+) currents in human embryonic kidney cells stably

Studies on vesicle formation by the Coat Protein I (COPI) complex have contributed to a basic understanding of how vesicular transport is initiated. Phosphatidic acid (PA) and diacylglycerol (DAG) have been found previously to be required for the fission stage

Diacylglycerol kinase (DGK) η plays important roles in various patho-physiological events such as oncogenesis. In this study, we performed an enzymological characterization of DGKη splice variant 1 (DGKη1). The Km value for diacylglycerol was 0.14 mol%. Intriguingly, the Km value
