CERS6, also known as Ceramide Synthase 6, is an enzyme involved in the biosynthesis of ceramides, which are essential components of cell membranes and serve as signaling molecules in various cellular processes. Positioned within the endoplasmic reticulum (ER) of cells, CERS6 plays a crucial role in catalyzing the synthesis of ceramides by acylating sphingoid bases with fatty acyl-CoA substrates. One of the primary functions of CERS6 is its involvement in the generation of specific ceramide species with distinct acyl chain lengths and saturation levels. Ceramides produced by CERS6 can vary in their fatty acyl composition, which influences their biophysical properties and...
