High glycogen in oysters contributes to their flavor, quality, and hardiness, making it a crucial target trait for breeding purposes. Until now, the upstream regulatory mechanism for glycogen synthesis has remained unclear. Protein phosphatase-1 regulatory subunit 3 (PPP1R3) is a member of a family that directs the protein phosphatase-1 (PP1) to glycogen, resulting in the activation of glycogen synthase (GS) and the inactivation of glycogen phosphorylase (GP). However, their functions in molluscan species have remained unclear until now. In our study, we verified the function of the PP1 alpha/PPP1R3D pathways in the glycogen metabolism process in Crassostrea gigas. Initially, we conducted a phylogenetic analysis and identified two PP1 and PPP1R3 members in molluscan species, emphasizing copy number variations in eukaryotic animals. Additionally, we identified distinct substitutions of conserved motifs specific to bivalves, Cephalopoda, or Gastropods, revealing functional diversity in PP1 and PPP1R3. Our primary focus was on PP1 alpha/PPP1R3D in the oyster C.gigas, detected in the muscle glycogen fraction of bivalve species, with mRNA expression showing a positive correlation with glycogen content.
