Bovine Peripheral Myelin Protein P2 (53-78) is a derivative composed of amino acid residues 53 to 78 from the peripheral myelin P2 protein of bovine origin. It acts as a T cell epitope and is used to induce experimental autoimmune neuritis (EAN) in Lewis rats.
Phosphatidylinositol-(4,5)-P2(1,2-dipalmitoyl), a synthetic analog of natural phosphatidylinositol (PtdIns) with C16:0 fatty acids at the sn-1 and sn-2 positions, maintains the inositol and diacylglycerol (DAG) stereochemistry of its natural counterpart. Although phosphatidylinositol phosphates constitute a minor fraction of total membrane phospholipids, they are pivotal in initiating and propagating cellular signals. This compound mirrors the activity of the natural phosphatidylinositol produced by PtdIns-4-phosphate 5-kinase's action on PtdIns-(4)-P1. Its hydrolysis by phosphoinositide (PI)-specific phospholipase C yields inositol triphosphate (IP3) and DAG, crucial secondary messengers in a complex signal transduction pathway.
p2Ca, a naturally processed peptide that derives from a ubiquitous enzyme, alpha-ketoglutarate dehydrogenase, and is recognized in association with the class I MHC protein, Ld, by a CTL clone (2C).
