Mechanisms for Reversible Regulation between G13 and Rho Exchange Factors [PDF]
Journal of Biological Chemistry, 2002 The heterotrimeric G proteins, G(12) and G(13), mediate signaling between G protein-coupled receptors and the monomeric GTPase, RhoA. One pathway for this modulation is direct stimulation by Galpha(13) of p115 RhoGEF, an exchange factor for RhoA. The GTPase activity of both Galpha(12) and Galpha(13) is increased by the N terminus of p115 Rho guanine ...

Purification and characterization of the alpha subunit of G13.
Journal of Biological Chemistry, 1994 Specific antisera were produced to peptides representing the carboxyl terminus of alpha 13, a recently identified alpha subunit of the heterotrimeric guanine nucleotide-binding proteins (G proteins). Immunodetection with the antisera indicated that the 43-kDa protein is expressed ubiquitously at low levels (0.005-0.05% of membrane protein) in tissues ...

Purification of the G-protein G13 from rat brain membranes [PDF]
Biochemical Journal, 1994 Significant amounts of G13, a member of the recently described G12-subfamily of heterotrimeric G-proteins, have been detected in rat brain membranes by specific antisera. The alpha-subunits of G13 (G alpha 13) were purified by using a combination of conventional and subunit-exchange chromatography.
