Has3 - hyaluronan synthase 3

Enables hyaluronan synthase activity. Involved in extracellular matrix assembly and extracellular polysaccharide biosynthetic process. Acts upstream of or within hyaluronan biosynthetic process. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; central nervous system; sensory organ; skin; and urinary system. Orthologous to human HAS3 (hyaluronan synthase 3). [provided by Alliance of Genome Resources, Apr 2022]
