Acetyl-coenzyme A transporter 1Acetyl-coenzyme A transporter 1 also known as solute carrier family 33 member 1 is a protein that in humans is encoded by the SLC33A1 gene.FunctionThe protein encoded by this gene is required for the formation of O-acetylated gangliosides. The encoded protein is predicted to contain 6 to 10 transmembrane domains, and a leucine zipper motif in transmembrane domain III.Clinical significanceDefects in this gene have been reported to cause spastic paraplegia autosomal dominant type 42 in one Chinese family, but not in similar patients of European descent.
