PR130 is an alias for the gene, Protein phosphatase 2 regulatory subunit B'', alpha, in humans. Other names include: Serine/threonine-protein phosphatase 2A regulatory subunit B'' subunit alpha; PP2A subunit B isoform R3 isoform; PP2A subunit B isoforms B''-PR72/PR130; PP2A subunit B isoforms B72/B130; Serine/threonine-protein phosphatase 2A 72/130 kDa regulatory subunit B; PP2A subunit B isoform PR72/PR130; PPP2R3; PR72; protein phosphatase 2, regulatory subunit B'', alpha. The encoded protein has an amino acid length of 1150 and a mass of 130.3 kDa. Other isoforms may exist. This gene shares homology with other species, including: Mouse, Rat, Zebrafish, Frog, Chicken.
