Protein attributes

Sequence length	735 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Transfers the glycosyl residue from UDP-Glc to the non-reducing end of alpha-1,4-glucan.
Catalytic activity	UDP-glucose ((1->4)-alpha-D-glucosyl)(n) = UDP + ((1->4)-alpha-D-glucosyl)(n+1).
Enzyme regulation	Allosteric activation by glucose-6-phosphate. Phosphorylation reduces the activity towards UDP-glucose. When in the non-phosphorylated state, glycogen synthase does not require glucose-6-phosphate as an allosteric activator; when phosphorylated it does.
Pathway	Glycan biosynthesis; glycogen biosynthesis.
Post-translational modification	Phosphorylation at Ser-8 is required for modification of Ser-11 by casein kinase I.
Sequence similarities	Belongs to the glycosyltransferase 3 family.
