Technical Data
Carbohydrate Sulfotransferase 5 (CHST5, Carbohydrate (N-acetylglucosamine 6-O) sulfotransferase 5, ALYE870, FLJ22167, GlcNAc6ST-3, GST4-alpha, hIGn6ST, I-GlcNAc6ST, Intestinal GlcNAc-6-sulfotransferase, MGC74625, PRO1886)
CHST5 (Carbohydrate sulfotransferase 5; also GlcNAc6ST-3, I-GlcNAc6ST and GST4 alpha) is likely a 53-56kD member of the sulfotransfease family of enzymes. It is a Golgi-embedded enzyme that is found in T cells, B cells and intestinal epithelium. It appears to act only on short carbohydrates and transfers sulfate to position #6 of mucin-associated GlcNAc. Human CHST5 is a 390aa type II transmembrane protein. It contains a short cytoplasmic segment (aa1-9) and a long luminal domain (aa28-390) that contains an enzymatic region (aa180-358). There is one alternate start site that is 22aa upstream of the standard site. Humans have a GST4-alpha and -beta gene, the result of gene duplication. Over aa28-390, these two gene products share 87% aa identity. Mouse has only one GST4 gene, and it is functionally related to human GST4- beta. Over aa 28-390, human GST4-alpha/CHST5 is 78% aa identical to mouse GST4.
