The FAM20B protein plays a key role in regulating mature glycosaminoglycan (GAG) chains by catalyzing xylose 2-O-phosphorylation in the glycosaminoglycan-protein linking region of the proteoglycan. This process is critical for the synthesis of sulfated GAGs (such as heparan sulfate and chondroitin sulfate) on the common GAG-protein linking region (GlcUAbeta1-3Galbeta1-3Galbeta1-4Xylbeta1-O-Ser) of the core protein. FAM20B Protein, Human (HEK293, Fc) is the recombinant human-derived FAM20B protein, expressed by HEK293 , with N-hFc labeled tag.
