Png, or Protein phosphatase 1 regulatory inhibitor subunit 14B, is a human gene encoded by PPP1R14B. It may also be known as: Protein phosphatase 1 regulatory subunit 14B; Phospholipase C-beta-3 neighbouring gene protein; PHI-1; PLCB3N; PNG; SOM172; protein phosphatase 1, regulatory (inhibitor) subunit 14B. The encoded protein has an amino acid length of 147 and a mass of 15.9 kDa. Png is a member of the PP1 inhibitor family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Arabidopsis, Frog.
