PPR1A rabbit pAb

Function: Inhibitor of protein-phosphatase 1. This protein may be important in hormonal control of glycogen metabolism. Hormones that elevate intracellular cAMP increase I-1 activity in many tissues. I-1 activation may impose cAMP control over proteins that are not directly phosphorylated by PKA. Following a rise in intracellular calcium, I-1 is inactivated by calcineurin (or PP2B). Does not inhibit type-2 phosphatases. PTM: Phosphorylation of Thr-35 is required for activity. similarity: Belongs to the protein phosphatase inhibitor 1 family. subunit: Interacts with PPP1R15A.
