AI118493, DNA for thyroid hormone receptor binding site 258bp, P2R3A_HUMAN, PP2A subunit B B72/B130 isoforms, PP2A subunit B isoform PR72/PR130, PP2A subunit B isoform R3 isoform, PP2A subunit B isoforms B72/B130, PP2A subunit B PR72/PR130 isoforms, PP2A subunit B R3 isoform, PPP2R3, Ppp2r3a, PR130, PR59, PR72, Serine/threonine protein phosphatase 2A 72/130 kDa regulatory subunit B, Serine/threonine-protein phosphatase 2A 72/130 kDa regulatory subunit B.
The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment.
