glycogenin Self-glucosylates, via an inter-subunit mechanism, to form an oligosaccharide primer that serves as substrate for glycogen synthase. Belongs to the glycosyltransferase 8 family. Glycogenin subfamily. Highly expressed in skeletal muscle and heart, with lower levels in brain, lung, kidney and pancreas. 3 alternatively spliced human isoforms have been reported.
