Protein Kinase A Subunit α Catalytic and A Kinase Anchoring Protein 79 in Human Placental Mitochondria

Components of protein phosphorylation signalling systems have been discovered in mitochondria and it has been proposed that these molecules modulate processes including oxidative phosphorylation, apoptosis and steroidogenesis. We used electrophoresis and Western blots probed with specific antibodies to protein kinase A α catalytic subunit (PKAα Cat) and A kinase anchoring protein of approximate...

Phytophthora sojae Effector PsCRN70 Suppresses Plant Defenses in Nicotiana benthamiana

Phytophthora sojae, an oomycete pathogen, produces a large number of effector proteins that enter into host cells. The Crinklers (Crinkling and Necrosis, CRN) are cytoplasmic effectors that are conserved in oomycete pathogens and their encoding genes are highly expressed at the infective stages in P. sojae. However, their roles in pathogenesis are largely unknown. Here, we functionally characte...

Activation of the Phosphatidylinositol 3-Kinase Vps34 by a G Protein α Subunit at the Endosome

In the yeast Saccharomyces cerevisiae, the G protein bg subunits are essential for pheromone signaling. The Ga subunit Gpa1 can also promote signaling, but the effectors in this pathway are not well characterized. To identify candidate Gpa1 effectors, we expressed the constitutively active Gpa1 mutant in each of nearly 5000 gene-deletion strains and measured mating-specific responses. Our analy...
