CC -!- FUNCTION: Bifunctional glycosyltransferase with both alpha-1,3-
CC xylosyltransferase and beta-1,3-glucuronyltransferase activities
CC involved in the maturation of alpha-dystroglycan (DAG1) by
CC glycosylation leading to DAG1 binding to laminin G-like domain-
CC containing extracellular proteins with high affinity. Elongates the
CC glucuronyl-beta-1,4-xylose-beta disaccharide primer structure initiated
CC by B4GAT1 by adding repeating units [-3-Xylose-alpha-1,3-GlcA-beta-1-]
CC to produce a heteropolysaccharide. Requires the phosphorylation of core
CC M3 (O-mannosyl trisaccharide) by POMK to elongate the glucuronyl-beta-
CC 1,4-xylose-beta disaccharide primer (By similarity). Plays a key role
CC in skeletal muscle function and regeneration (By similarity).
CC {ECO:0000250|UniProtKB:O95461, ECO:0000250|UniProtKB:Q9Z1M7}.
