PPP2R5D
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. PP2A consists of a common heterodimeric core enzyme, composed of a 36 kDa catalytic subunit (subunit C) and a 65 kDa constant regulatory subunit (PR65 or subunit A), that associates with a variety of regulatory subunits. Proteins that associate with the core dimer include three families of regulatory subunits B (the R2/B/PR55/B55, R3/B''/PR72/PR130/PR59 and R5/B'/B56 families), the 48 kDa variable regulatory subunit, viral proteins, and cell signaling molecules. Interacts with SGOL1. By retinoic acid; in neuroblastoma cell lines. Isoform Delta-2 is widely expressed. Isoform Delta-1 is highly expressed in brain. Belongs to the phosphatase 2A regulatory subunit B56 family. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
