Anti-CHSTF CHST15 Antibody

Carbohydrate sulfotransferase 15;2.8.2.33; B-cell RAG-associated gene protein; hBRAG; N-acetylgalactosamine 4-sulfate 6-O-sulfotransferase; GalNAc4S-6ST; CHST15; BRAG, GALNAC4S6ST, KIAA0598;

Expressed in B-cell-enriched tissues but not in fetal or adult thymus. Expressed in fetal and adult spleen, lymph node, tonsil, bone marrow and peripheral leukocytes. Not expressed in T-cells. In pro-B, pre-B, and mature B-cell lines, it colocalizes with RAG1.

Sulfotransferase that transfers sulfate from 3'- phosphoadenosine 5'-phosphosulfate (PAPS) to the C-6 hydroxyl group of the GalNAc 4-sulfate residue of chondroitin sulfate A and forms chondroitin sulfate E containing GlcA-GalNAc (4,6-SO (4) ) repeating units. It also transfers sulfate to a unique non- reducing terminal sequence, GalNAc (4SO4) -GlcA (2SO4) -GalNAc (6SO4), to yield a highly sulfated structure similar to the structure found in thrombomodulin chondroitin sulfate. May also act as a B- cell receptor involved in BCR ligation-mediated early activation that mediate regulatory signals key to B-cell development and/or regulation of B-cell-specific RAG expression; however such results are unclear in vivo.
