Sulfatide synthesis and its subcellular distribution kinetics was followed in the myelinating brain of 17-day-old mice. Pulse-labeling-chasing conditions were achieved by an intraperitoneal injection of (35S)sulfate followed 2 h later by a second injection of a high dose of unlabeled sulfate. At 1, 2, 3, 4, and 6 h after the (35S)sulfate injection, the brains were removed, homogenized, and subcellular fractions were obtained by differential and discontinuous sucrose gradient centrifugation (Eichberg, J., Whittaker, V. P., and Dawson, R. M. (1964) Biochem. J. 92, 91-100). The microsomal membranes were further subfractionated (Siegrist, H. P., Burkart, T., Wiesmann, U. N., Herschkowitz, N. N., and Spycher, M. A. (1979) J. Neurochem. 33, 497-504) into light myelin, plasma membranes, Golgi vesicles, endoplasmic reticulum membranes, and heavy vesicles associated with acid hydrolase activities. The [35S]sulfatide-labeling kinetics was measured in all subcellular fractions. The results indicate that sulfatides are synthesized in the Golgi-endoplasmic reticulum complex and transferred in vesicles at least partially associated with lysosomes to the myelin membranes. The association of sulfatides with lysosomes could explain the existence of the previously described labile pool of newly synthesized sulfatides (Burkart, T., Hofmann, K., Siegrist, H. P., Herschkowitz, N. N., and Wiesmann, U. N. (1981) Dev. Biol. 83, 42-48) and also could be a form of vesicular transport to the myelin.
