Preferred Label : GTP-Binding protein alpha subunits;
MeSH definition : The GTPase-containing subunits of heterotrimeric GTP-binding proteins. When dissociated
from the heterotrimeric complex these subunits interact with a variety of second messenger
systems. Hydrolysis of GTP by the inherent GTPase activity of the subunit causes it
to revert to its inactive (heterotrimeric) form. The GTP-Binding protein alpha subunits
are grouped into families according to the type of action they have on second messenger
systems.;
MeSH synonym : g protein alpha subunit; gtp-binding protein alpha subunit; gtp binding protein alpha subunit; g-protein alpha subunit; alpha subunit, g-protein; GTP binding protein alpha subunits;
