The protein encoded by the HAS3 gene is involved in the synthesis of the unbranched glycosaminoglycan hyaluronan, orhyaluronic acid, which is a major constituent of the extracellular matrix. This gene is a member of the NODC/HAS genefamily. Compared to the proteins encoded by other members of this gene family, this protein appears to be more of aregulator of hyaluronan synthesis. Two transcript variants encoding different isoforms have been found for this gene.(provided by RefSeq)
