Rho-Rac guanine nucleotide exchange factor 2 (ARHGEF2), which activates Ras homolog family member A (RHOA), is anchored to the microtubule network and sequestered in an inhibited state through binding to dynein light chain Tctex-1 type 1 (DYNLT1). We showed in mammalian cells that liver kinase B1 (LKB1) activated the microtubule affinity-regulating kinase 3 (MARK3), which in turn phosphorylated ARHGEF2 at Ser151 This modification disrupted the interaction between ARHGEF2 and DYNLT1 by generating a 14-3-3 binding site in ARHGEF2, thus causing ARHGEF2 to dissociate from microtubules. |

Here we identify a region in the carboxyl terminus of gef-h1 that is important for suppression of its guanine nucleotide exchange activity by microtubules. This portion of the protein includes a coiled-coil motif, a proline-rich motif that may interact with src homology 3 domain-containing proteins, and a potential binding site for 14-3-3 proteins. We show that phosphorylation of gef-h1 at ser(885) by pak1 induces 14-3-3 binding to the exchange factor and relocation of 14-3-3 to microtubules. |

We also show that par1b-induced serine 885/serine 959 phosphorylation inhibits rhoa-specific gef activity of gef-h1. As a consequence, gef-h1 phosphorylated on both of the serine residues loses the ability to stimulate rhoa and thereby fails to induce rhoa-dependent stress fiber formation |

The Rho Family GEF Lfc Interacts with Neurabin and Spinophilin. Neurabin and spinophilin are homologous protein phosphatase 1 and actin binding proteins that regulate dendritic spine function. The results obtained in the present study suggest a mechanism by which neurabin or spinophilin contributes to the organization of the F-actin cytoskeleton in dendritic spines, and in turn to the regulation of spine morphology, via the activity-dependent recruitment of the Rho-specific GEF Lfc |
