O-Phospho-L-serine (CAS 407-41-0)

O-Phospho-L-serine, a naturally occurring phospholipid, holds a vital presence within the cell membranes of all eukaryotic cells. Functioning as a small molecule, it plays a role in cell signaling pathways and participates in various cellular processes, including cell growth, differentiation, and apoptosis. PS assumes the significant responsibility of regulating cell membrane structure and function while actively engaging in diverse metabolic and biochemical pathways. The precise mechanism of action of O-Phospho-L-serine remains partially elucidated. It is understood that Phosphoserine binds to specific proteins, such as G proteins, thereby modulating their activity by either activating or inhibiting them. Moreover, Phosphoserine demonstrates an ability to interact with other proteins like nuclear receptors, thereby exerting regulatory control over their activity. Additionally, O-Phospho-L-serine engages in interactions with other phospholipids, such as phosphatidylinositol, consequently influencing their activity as well. O-Phospho-L-serine may act to elicit a range of biochemical and physiological effects, including the regulation of cell proliferation, differentiation, and apoptosis. It also participates in vital functions such as cell signaling pathways, membrane structure and function, as well as metabolic pathways.
