Hyaluronan synthase 3 (HAS3)

Catalyzes the addition of GlcNAc or GlcUA monosaccharides into the nascent hyaluronan polymer. Therefore, it's vital to hyaluronan synthesis a major component of most extracellular matrices which has a structural role in cells architectures and regulates cell adhesion, migration and differentiation.

This is one of the isozymes catalyzing that response (By similarity). .
