Regulation and Physiological Functions of G12/13-Mediated Signaling Pathways [PDF]

Neurosignals, 2009
Accumulating data indicate that G12 subfamily (Galpha12/13)-mediated signaling pathways play pivotal roles in a variety of physiological processes, while aberrant regulation of this pathway has been identified in various human diseases. It has been demonstrated that Galpha12/13-mediated signals form networks with other signaling proteins at various ...
