Identification of bdm-1, a gene involved in G protein b-subunit function and a-subunit accumulation

Targeted disruption of Ga and Gb genes has established the requirement of an intact G protein signaling pathway for optimal execution of several important physiological processes, including pathogenesis, in the chestnut blight fungus Cryphonectria parasitica. We now report the identification of a G protein signal transduction component, beta disruption mimic factor-1, BDM-1. Disruption of the c...

Trichoderma atroviride G-protein alpha-subunit gene tga1 is involved in mycoparasitic coiling and conidiation.

The soil fungus Trichoderma atroviride, a mycoparasite, responds to a number of external stimuli. In the presence of a fungal host, T. atroviride produces hydrolytic enzymes and coils around the host hyphae. In response to light or nutrient depletion, asexual sporulation is induced. In a biomimetic assay, different lectins induce coiling around nylon fibers; coiling in the absence of lectins ca...

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 ...

Cloning and Expression of Heat Shock Protein 60kDa Gene from Brucella melitensis as Subunit Vaccine

Brucellosis is caused by the bacterium Brucella and affects various domestic and wild species. GroEL (Heat Shock Protein 60kDa) as one of the major antigens that stimulate the immune system, increases Brucella survival. The aim of the current study was to clone and express GroEL in Escherichia coli in order to design subunit vaccine. Amplifying was performed using specific primers. The full-len...

High glucose condition down-regulates the inhibitory G-protein subunit, Gαi, in pheochromocytoma PC12 cells

Introduction: G-proteins have an important role in the cell signaling of numerous receptors. The situation of G-proteins in health and disease and their critical role in the development of diabetic side effects is an interested scientific field. Here, the changes in the expression of G-protein subunits (Gαi, Gαs and Gβ) were evaluated in hyperglycemic situation of PC12 cells as...
