The recombinant human N-deacetylase/N-sulfotransferase 3 (NDST3) protein is a key enzyme involved in the biosynthesis of heparan sulfate (HS) and heparin sulfate, which are critical components of the extracellular matrix and cell surfaces. NDST3 belongs to the NDST enzyme family, which catalyzes the dual enzymatic reactions of N-deacetylation and N-sulfation during HS chain modification. These modifications determine the sulfation patterns of HS, influencing its interactions with growth factors, cytokines, and other signaling molecules that regulate cellular processes such as adhesion, proliferation, and differentiation.
NDST3 is expressed in various tissues and plays a role in developmental and pathological conditions, including cancer, inflammation, and neurological disorders. Dysregulation of NDST3 has been linked to altered HS sulfation patterns, which may contribute to disease progression by modulating signaling pathways like FGF2 and Wnt.
Recombinant NDST3 is typically produced in mammalian or insect expression systems, retaining its enzymatic activity for use in structural and functional studies. Its applications include elucidating HS biosynthesis mechanisms, screening for enzyme inhibitors or activators, and exploring therapeutic strategies targeting HS-dependent pathways. Research on NDST3 provides insights into how glycan modifications impact cellular communication and disease, highlighting its potential as a biomarker or therapeutic target.
