Domain composition and phylogeny of PHLPP isoforms
A. Domain composition of PHLPP family members showing the Ras association domain (RA; dark blue), pleckstrin homology domain (PH; cyan), Leucine rich repeat (LRR; orange) region, PP2C domain (yellow), and PDZ binding motif (pink). Gray arrow head denotes the splice site for PHLPP1β. B. Phylogenetic tree of PPM phosphatase domains (human) showing PHLPP as a discrete subfamily (highlighted in yellow) of the PP2C class. Sequences were aligned using ClustalW (Gonnet matrix)
