The glycogenin-linked primer allows glycogen synthase to extend glucose chains, while the glycogen branching enzyme creates the α-1,6 linkages that produce mature glycogen. GYG1 and related glycogenin proteins are therefore important for glycogen structure, glucose storage, liver and muscle metabolism, and normal energy regulation.

It creates α-1,6 glycosidic linkages between glucose chains, working together with glycogenin and glycogen synthase during glycogenesis. Proper glycogen branching allows efficient glucose storage and mobilization in the liver and skeletal muscle. Defects in GBE1 can cause glycogen storage disease type IV, highlighting the importance of glycogen structure in normal metabolism.
