INTEGRATION OF SIGNALS TO THE CYTOSKELETON BY MODULAR PROTEINS


Mena interacts with receptors, focal adhesion components and bacterial pathogens through its EVH1 domain, and has multiple motifs that potentially couple to the actin cytoskeleton. UNC-73/Trio has an N-terminal domain related to yeast Sec 14, multiple spectrin repeats, and two DH-PH domains that activate Rac and Rho respectively. The signaling pathways that lie upstream of UNC-73/Trio are not well established.
