sphinganine kinase activity

Definition

Target type: molecularfunction

Catalysis of the reaction: ATP + sphinganine = ADP + sphinganine 1-phosphate. [EC:2.7.1.91]

Sphinganine kinase activity is a key enzymatic step in the biosynthesis of sphingosine-1-phosphate (S1P), a bioactive lipid mediator involved in diverse cellular processes. This activity is catalyzed by sphinganine kinases (SPHKs), which phosphorylate sphinganine at the 1-hydroxyl group, generating sphingosine-1-phosphate (S1P). The reaction requires ATP as a phosphate donor. S1P is a pleiotropic signaling molecule that exerts its effects through binding to five G protein-coupled receptors (S1P1-5) and has been implicated in various physiological and pathological processes, including cell survival, proliferation, migration, inflammation, angiogenesis, and immune regulation. SPHKs exist in multiple isoforms (SPHK1, SPHK2, and SPHK3) with distinct tissue distribution and regulatory mechanisms. They are crucial for maintaining cellular homeostasis and play a role in the development of various diseases. SPHK activity is regulated by a variety of factors, including cellular stress, growth factors, and cytokines. The dysregulation of SPHK activity has been linked to several diseases, including cancer, cardiovascular disease, and neurodegenerative disorders.'
