Schematic representation of wild-type and truncated Tiam1 cDNA
constructs used in this study. Proteins are depicted to scale. M,
myristoylation signal; P, region rich in proline, glutamate, serine,
and threonine; PHn and PHc, NH2-terminal and COOH-terminal
pleckstrin homology domains; DHR, Discus-large homology region; DH, Dbl
homology domain; WT, wild type.
