CC   -!- FUNCTION: May catalyze both beta-1,3 and beta-1,4 glycosidic linkage on
CC       beta-D-glucan. Essential for (1,3;1,4)-beta-D-glucans synthesis in
CC       grasses and cereals (Poaceae). The mixed-linked glucans (which are not
CC       present in walls of dicotyledons or most other monocotyledonous plants)
CC       are particularly important constituents of the walls of the starchy
CC       endosperm and aleurone cells of cereal grains such as oats, wheat, rice
CC       and barley. They can account for up to 70% by weight of the wall (By
CC       similarity). {ECO:0000250, ECO:0000269|PubMed:16574868}.
CC   -!- SUBCELLULAR LOCATION: Golgi apparatus membrane {ECO:0000305}; Multi-
CC       pass membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase 2 family. Plant
CC       cellulose synthase-like F subfamily. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAF21858.2; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
