    This study accomplished a cell-free reconstitution of the sphingolipid regulation of the ORMDL3-SPTLC1 complex to probe the underlying regulatory mechanism. Sphingolipid and ORMDL-dependent regulation of SPTLC1 was demonstrated in isolated membranes, essentially free of cytosol. This suggests that this regulation does not require soluble cytosolic proteins or small molecules such as ATP.

    A novel SPTLC2-S384F variant in 2 unrelated HSAN1 families resulted in elevated plasma 1-deoxySL levels. Expression of this mutant in HEK293 cells increased 1-deoxySL formation. The substrate specificity is affected by phosphorylation at this position.
