A G-protein beta-subunit is essential for Dictyostelium development.
Recent studies have demonstrated that G-protein-linked signal transduction pathways play a significant role in the developmental program of the simple eukaryotic organism Dictyostelium. We have reported previously the isolation of a G-protein beta-subunit and present here a more complete analysis of this gene. Low-stringency Southern blots and RFLP mapping studies suggest that the beta-subunit ...
متن کاملA G-Protein Subunit Required for Sexual and Vegetative Development and Maintenance of Normal G Protein Levels in Neurospora crassa
The genome of the filamentous fungus Neurospora crassa contains a single gene encoding a heterotrimeric G-protein subunit, gnb-1. The predicted GNB-1 protein sequence is most identical to G proteins from the filamentous fungi Cryphonectria parasitica and Aspergillus nidulans. N. crassa GNB-1 is also 65% identical to the human GNB-1 protein but only 38 and 45% identical to G proteins from buddin...
متن کاملA regulator of G protein signaling-containing kinase is important for chemotaxis and multicellular development in dictyostelium.
We have identified a gene encoding RGS domain-containing protein kinase (RCK1), a novel regulator of G protein signaling domain-containing protein kinase. RCK1 mutant strains exhibit strong aggregation and chemotaxis defects. rck1 null cells chemotax approximately 50% faster than wild-type cells, suggesting RCK1 plays a negative regulatory role in chemotaxis. Consistent with this finding, overe...
متن کاملG-Protein α-Subunit Gsα Is Required for Craniofacial Morphogenesis.
The heterotrimeric G protein subunit Gsα couples receptors to activate adenylyl cyclase and is required for the intracellular cAMP response and protein kinase A (PKA) activation. Gsα is ubiquitously expressed in many cell types; however, the role of Gsα in neural crest cells (NCCs) remains unclear. Here we report that NCCs-specific Gsα knockout mice die within hours after birth and exhibit dram...
متن کاملSuperoxide signalling required for multicellular development of Dictyostelium.
Reactive oxygen species are known to have a signalling role in many organisms. In bacteria and yeast various response systems have evolved to combat oxidative stress which are triggered by reactive oxygen species. Mammals and plants are known to actively generate reactive oxygen species such as superoxide during signalling responses to a variety of extracellular factors. We report here the gene...
