Identification
HMDB Protein ID CDBP03167
Secondary Accession Numbers Not Available
Name Protein phosphatase 1 regulatory subunit 1A
Description Not Available
Synonyms
  1. I-1
  2. IPP-1
  3. Protein phosphatase inhibitor 1
Gene Name PPP1R1A
Protein Type Enzyme
Biological Properties
General Function Involved in phosphoprotein phosphatase inhibitor activity
Specific 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
