Abstract:
The work within this thesis is concerned with the creation of a temperature-sensitive Schizosaccharomyces pombe marker protein, and the regulation of the pheromone communication system of Sz. pombe reporter strains by RGS proteins. There are a limited number of marker proteins available for use in the genetic manipulation of Sz. pombe, and the generation of a temperature-sensitive Ura4p was envisaged to expand the scope of carrying out sequential gene disruptions in the fission yeast. PCR-based mutagenesis was used to introduce mutations in the ura4 cassette, and a leucine to proline mutation

Abstract:
G proteins are alpha-beta-gamma heterotrimers in the resting state, bound to GDP and complexed with the unbound receptor. Once the receptor becomes occupied, the alpha subunit exchanges GDP for GTP, becomes activated, and dissociates from the receptor and can stimulate or inhibit many intracellular activities such as phosphorylation and channel conductance. For example, Gs and Golf alpha subunits stimulate and Gi alpha subunits inhibit adenylyl cyclase. Go alpha subunits are abundant in brain, but are of unknown function. cDNAs for the alpha subunit have been cloned. In order to examine the r

Abstract:
Regulators of G protein signaling (RGSs) are negative regulators of G protein coupled receptors (GPCRs). Our lab has demonstrated that yeast Saccharomyces cerevisiae is a useful system to study RGS and G protein signaling. Mammalian RGSs can be expressed in yeast and favored to interact with mammalian GPCRs as well.<br>Based on the observation that human RGS1 causes yeast cell growth arrest, I therefore used RGS1 expressing yeast cells to screen a mouse T cell cDNA library in order to find potential interacting proteins. From the screen, I identified a mouse sphingomyelin synthase 1 (SMS1) cDN

Palmitoylation variant GPCR-G protein fusion proteins were created between the porcine u2A-adrenoceptor or the human 5-HT1A-serotonin receptor and the pertussis toxin resistant, Cys35lIle, form of the rat Go1u protein. These palmitoylation-variant fusions were transiently expressed in HEK293T cells prior to analysis of the regulation of palmitoylation and the functional consequences of palmitoylation for both the GPCR and G protein parts of the fusions. When the regulation of palmitoylation was studied for u2A-adrenoceptor-GoluCys35IIle fusion proteins, dynamic palmitoylation and depalmitoylat

Abstract:
The Rho family of GTPases plays a crucial role in the regulation of diverse cellular processes, including proliferation and actin cytoskeletal rearrangement to promote cell migration. However, dysregulation of RhoGTPases has been associated with disease, particularly cancers such as leukemia. Despite this, RhoGTPases are rarely mutated in cancer. Rather, dysregulation of their regulatory proteins through mutation or overexpression contributes to disease pathogenesis. RhoGTPases are activated through Rho guanine nucleotide exchange factors (GEFs). Although over eighty RhoGEFs have been identifi

Abstract:
G-protein coupled receptor signaling (GPCR) is essential for regulating a large variety of hormonal, sensory and neuronal processes in eukaryotic cells. Because the regulation of these physiological responses is critical, GPCR signaling pathways are carefully controlled at different levels within the cascade. Phosducin-like protein 1 (PhLP1) can bind the G protein βγ dimer and participate in GPCR signaling. Recent evidence has supported the concept that PhLP1 can serve as a co-chaperone of the eukaryotic cytosolic chaperonin complex CCT/TRiC to mediate G βγ assembly. Although a general mechani

Abstract:
Signal transduction by G-proteins (a heterotrimer membrane protein composed of an α, β, and γ subunit) requires that the α-subunit undergoes a transition from a GDP-bound inactive state to an activated GTP-bound state. The exchange of GDP for GTP leads to a conformational change in the α-subunit that results in the loss of affinity for the βγ subunits. We predicted that appropriate genetic manipulation of key regions of the α-subunit could result in the induction of the active conformation that would mimic at least in part the activated GTP-bound state.
