Differential complementation of a Neurospora crassa Galpha(i) mutation using mammalian Galpha protein genes.

Abstract excerpt

Heterotrimeric (alphabetagamma) G proteins interact with sensory receptors to transduce signals to downstream effectors in eukaryotes. We previously reported that GNA-1 from Neurospora crassa is a microbial member of the Galphai family found in higher organisms. Deletion of gna-1 leads to female sterility, slower growth rates on normal and hyperosmotic solid medium, and increased resistance to heat and oxidative...
