Protein Name: Serine/threonine-protein phosphatase 2A 55 kDa regulatory subunit B delta isoform

UniprotKB/SwissProt ID: Q66LE6 (Q66LE6)

Gene Name: PPP2R2D

Organism: Homo sapiens (Human)

Function: Substrate-recognition subunit of protein phosphatase 2A (PP2A) that plays a key role in cell cycle by controlling mitosis entry and exit. Involved in chromosome clustering during late mitosis by mediating dephosphorylation of MKI67 (By similarity). The activity of PP2A complexes containing PPP2R2D (PR55-delta) fluctuate during the cell cycle: the activity is high in interphase and low in mitosis (By similarity)
