Scott‡ From the Howard Hughes Medical Institute, Vollum Institute, Oregon Health Sciences University, Portland, Oregon 97201 Guanine nucleotide exchange factors of the Dbl family exchange factors such as PDZ Rho-GEF, KIAA0380, or relay signals from membrane receptors to Rho family GTRAP48 (12–14). GTPases. We now demonstrate that a longer transcript A universal hallmark of exchange factors that activate GTP- of the Lbc gene encodes a chimeric molecule, which we ases of the Rho family is a conserved region of 250 residues have called AKAP-Lbc, that functions as an A-kinase- that contains a Dbl homology (DH) domain followed by a pleck- anchoring protein (AKAP) and a Rho-selective guanine strin homology domain (9). The DH domain contains the nu- nucleotide exchange factor.
