| T1 |
0-77 |
Sentence |
denotes |
Molecular cloning and expression of a novel chondroitin 6-O-sulfotransferase. |
| T2 |
78-308 |
Sentence |
denotes |
A novel human chondroitin 6-O-sulfotransferase, designated C6ST-2, was identified by BLAST analysis of expressed sequence tag using the sequence of a previously described human chondroitin 6-O-sulfotransferase (C6ST-1) as a probe. |
| T3 |
309-448 |
Sentence |
denotes |
The new cDNA sequence revealed an open reading frame coding for a protein of 486 amino acids with a type II transmembrane protein topology. |
| T4 |
449-599 |
Sentence |
denotes |
The amino acid sequence displayed 24% identity to the human C6ST-1, and the highest sequence identity was found in the COOH-terminal catalytic domain. |
| T5 |
600-759 |
Sentence |
denotes |
The expression of a soluble recombinant form of the protein in COS-1 cells produced an active sulfotransferase with marked specificity for polymer chondroitin. |
| T6 |
760-930 |
Sentence |
denotes |
In contrast, keratan sulfate and oligosaccharides containing the Galbeta1-4GlcNAc sequence, which are good acceptor substrates for the C6ST-1, hardly served as acceptors. |
| T7 |
931-1108 |
Sentence |
denotes |
The identification of the reaction product indicated that the enzyme is a novel chondroitin 6-O-sulfotransferase (C6ST-2) that mainly transfers sulfate to N-acetylgalactosamine. |
| T8 |
1109-1201 |
Sentence |
denotes |
The coding region of C6ST-2 was contained in a single exon and localized to chromosome Xp11. |
| T9 |
1202-1306 |
Sentence |
denotes |
Northern blot analysis of human brain poly(A)(+) RNA revealed a single transcript of 2.4 kilobase pairs. |
| T10 |
1307-1490 |
Sentence |
denotes |
Reverse transcription-polymerase chain reaction analysis showed that C6ST-2 is developmentally regulated in various tissues with expression persisting through adulthood in the spleen. |
| T11 |
1491-1809 |
Sentence |
denotes |
Thus, we demonstrated the redundancy in chondroitin 6-O-sulfotransferases capable of forming chondroitin 6-sulfate, which is important for understanding the mechanisms leading to specific changes in the sulfation profile of chondroitin sulfate chains in various tissues during development and malignant transformation. |
