Background Descriptions	The N-deacetylation and N-sulfation of N-acetylglucosamine residues in heparan sulfate and heparin initiate a set of biochemical reactions, which lead to the synthesis of oligosaccharide sequences that have specific ligand binding properties (1). These reactions are catalyzed by the monomeric enzymes GlcNAc Ndeacetylase/N-sulfotransferases (NDSTs), which have two catalytic activities (1). Multiple NDST isozymes have been identified, each having unique tissue distribution and enzymatic properties (2). Phylogenetic data suggests that NDST1-4 evolved from a common ancestral gene, which diverged to give rise to two subtypes, NDST1/2 and NDST3/4 (2). NDST1, which maps to human chromosome 5q32-q33.1, shares the most homology with NDST2, which maps to human chromosome 10q22 (3,4). The least conserved amino acids between these two enzymes are found in the N-terminus/putative transmembrane regions (3). The human NDST3 and NDST4 genes are closely linked on chromosome 4, mapping to chromosome 4q25-26 and 4q26-27, respectively (2,5,6). RT-PCR analysis of various mouse tissues reveals a restricted pattern of NDST3 and NDST4 mRNA expression when compared with that of NDST1 and NDST2, which are abundantly and ubiquitously expressed (2).

Protein Information
Name	NDST4
Synonyms	HSST4
Function	Essential enzyme that catalyzes the N-sulfation of glucosamine (GlcNAc) of the glycosaminoglycan in heparan sulfate (PubMed:29158133). Modifies the GlcNAc-GlcA disaccharide repeating sugar backbone to make N-sulfated heparosan, a prerequisite substrate for later modifications in heparin biosynthesis (PubMed:29158133). Has no deacetylase activity but high sulfotransferase activity (PubMed:29158133). Plays a crucial role in the differentiation of colonic progenitor cells (By similarity).
Cellular Location	Golgi apparatus membrane; Single- pass type II membrane protein
