Figure 2

Cartoon representation of rat PITPα complexed to PtdCho. (a). Structural domains of the class I PITPs displayed on a representative PITP (PDB:1T27). The lipid binding core is shown in blue, the regulatory loop in green, and the C-terminal region in red. The PtdCho molecule is in transparent spheres with standard CPK coloring; (b) Conserved sequence motifs mapped onto the same structure. The four conserved sequence motifs; m4, m9, m13, m14, and m23, representing branch points in the cladogram shown in Figure 3 are in purple and are annotated. The remaining sequence motifs are in gold, regions not present in conserved sequence motifs are colored grey; (c). Image B is rotated 90° counterclockwise around a vertical axis.
