Abstract
In this study we describe the identification and characterization of a novel cytosolic protein of the guanine exchange factor (GEF) family. The human cDNA corresponds to predicted human protein FLJ00128/FLJ10357 located on chromosome 14q11.2. The deduced protein sequence contains in its C-terminus a RhoGEF domain followed by a pleckstrin domain. Its N-terminus, central region and RhoGEF/pleckstrin domain are homologous to the recently identified zebrafish Quattro protein, which is involved in morphogenetic movements mediated by the actin cytoskeleton. Based on the homology of our protein's RhoGEF domain to the RhoGEF domains of Trio, Duo and Duet and its homology with Quattro, we named it Solo. The Solo mRNA is ubiquitously expressed but enriched in brain, its expression peaks perinatally and it undergoes extensive alternative splicing. In both myoblasts and neuroblastoma cells, the Solo protein is concentrated around the nucleus.
