TheDictyosteliumGα5 subunit has been shown to reduce cell viability, inhibit folate chemotaxis and accelerate tip morphogenesis and gene expression during multicellular development. Alteration of the D-motif (mitogen-activated protein kinase docking site) at the amino terminus of the Gα5 subunit or the loss of extracellular signal-regulated kinase (ERK)1 diminished the lethality associated with the overexpression or constitutive activation of the Gα5 subunit. The amino-terminal D-motif of the Gα5 subunit was also found to be necessary for the reduced cell size, small aggregate formation and precocious developmental gene expression associated with Gα5 subunit overexpression. This D-motif also contributed to the aggregation delay in cells expressing a constitutively active Gα5 subunit, but the D-motif was not necessary for the inhibition of folate chemotaxis. These results suggest that the amino-terminal D-motif is required for some but not all phenotypes associated with elevated Gα5 subunit functions during growth and development and that ERK1 can function in Gα5 subunit-mediated signal transduction.
