TgPPKL is a unique serine/threonine protein phosphatase protein with a kelch-repeat domain. A Schematic diagram of the domain architecture of TgPPKL. PPKL contains kelch-repeat domains at the N-terminus and protein phosphatase domains at the C-terminus. A scale length of 50 amino acids is shown for the protein length displayed in the schematic. B Alignment of PPKL amino acid sequences from different species. PPKL was retrieved from Plasmodium (XP_001348804.1), Babesia (XP_001609688.1), Toxoplasma (GT1 PR59771.1), Cryptosporidium (XP_001388090.1), and Arabidopsis (NP_171844.6). Red and blue rectangular areas indicate relatively conserved amino acid sites
