Cytosolic glycogen branching enzyme (GBE1) associated with glycogen granules transfers terminal alpha(1,4) glucose blocks to form alpha(1,6) branches on growing glycogen molecules formed on glycogenin 1 (GYG1) complexed with unphosphorylated glycogen synthase 1 (GYS1-a) (Bao et al. 1996; Roach et al. 2012).
