Molecular cloning and expression of human chondroitin 6-sulfotransferase.
Using cDNA of chick chondroitin 6-sulfotransferase (C6ST), human C6ST cDNA has been isolated. The amino acid sequence of human C6ST displayed 74% identity to chick C6ST. The major difference in amino acid sequence between chick C6ST and human C6ST was the presence of a unique hydrophilic domain in human C6ST. A 7.8-kb message of C6ST was expressed ubiquitously in various human adult tissues, indicating a rather diverse function of C6ST.
