Putative Daphnia pulex PROTEIN PHOSPHATASE 2A (PP2A) proteins. (A) Alignment of Drosophila melanogaster PP2A catalytic subunit MICROTUBULE STAR (MTS) protein (Drome-MTS) with D. pulex MTS (Dappu-MTS). (B1). Alignment of D. melanogaster PP2A regulatory subunit WIDERBORST (WBT) protein (Drome-WBT) with D. pulex WBT A (Dappu-WBT A). (B2). Alignment of Dappu-WBT A and Dappu-WBT B. (C). Alignment of D. melanogaster PP2A regulatory subunit TWINS (TWS) protein (Drome-WBT) with D. pulex TWS (Dappu-TWS). In the line immediately below each sequence grouping, stars indicated amino acids that are identically conserved, while single and double dots denote amino acids that are similar in structure. In this figure, protein phosphatase 2A catalytic, coiled-coil and WD40 domains identified by SMART analyses are highlighted in dark green, pink and dark red, respectively.
