PR52, or Protein phosphatase 2 regulatory subunit B, gamma, is a human gene encoded by PPP2R2C. It may also be known as: Serine/threonine-protein phosphatase 2A 55 kDa regulatory subunit B gamma isoform; PP2A subunit B isoform B55-gamma; PP2A subunit B isoform PR55-gamma; PP2A subunit B isoform R2-gamma; PP2A subunit B isoform gamma; IMYPNO1; B55-GAMMA; IMYPNO; PR55G; protein phosphatase 2, regulatory subunit B, gamma. The encoded protein has an amino acid length of 447 and a mass of 51.5 kDa. Other isoforms may exist. PR52 is a member of the Phosphatase 2A regulatory subunit B family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
