Sphingosine kinase 1 in complex with PF-543
| ||||||||||||
Structural highlights
FunctionSPHK1_HUMAN Catalyzes the phosphorylation of sphingosine to form sphingosine 1-phosphate (SPP), a lipid mediator with both intra- and extracellular functions. Also acts on D-erythro-sphingosine and to a lesser extent sphinganine, but not other lipids, such as D,L-threo-dihydrosphingosine, N,N-dimethylsphingosine, diacylglycerol, ceramide, or phosphatidylinositol.[1] Publication Abstract from PubMedThe most potent inhibitor of Sphingosine Kinase 1 (SPHK1) so far identified is PF-543. The crystal structure of SPHK1 in complex with inhibitor PF-543 to 1.8 A resolution reveals the inhibitor bound in a bent conformation analogous to that expected of a bound sphingosine substrate but with a rotated head group. The structural data presented will aid in the design of SPHK1 and SPHK2 inhibitors with improved properties.
