| Outline of Final Research Achievements |
PLEKHG2 is a Rho family small G protein-specific guanine nucleotide exchange factor (RhoGEF) which is activated by the directly interaction with heterotrimeric G protein Gβγ subunits. However, there are no functional domains other than the Dbl homology (DH) domain and pleckstrin homology (PH) domain, which are active centers, in the structure of PLEKHG 2. In this study, functional regulation via interaction between molecules other than Gβγ subunits and PLEKHG2 was investigated. The interaction between PLEKHG2 and heterotrimeric G protein Gαs subunit, or ABL1, attenuate the activity of PLEKHG2. On the other hand, the interaction between PLEKHG2 and FHL1 activate the activity of PLEKHG2.
