The START PITP family. START PITPs are aligned by primary sequence using VectorNTI (Life Technologies), and the alignment is visualized as a cladogram. Proteins discussed in this review are highlighted in color. Accession numbers for the specific amino acid sequences used are in brackets. Class I PITPs are designated in blue, and class II PITPs in red. PITPs from ancient eukaryotes, including Toxoplasma and Trichomonas do not fall into either category.
