Ric-8A, a Gα protein guanine nucleotide exchange factor potentiates taste receptor signaling
Taste receptors for sweet, bitter and umami tastants are G-protein coupled receptors (GPCRs). While much effort has been devoted to understanding G-protein-receptor interactions and identifying the components of the signalling cascade downstream of these

Dietary Methionine Restriction Regulates Liver Protein Synthesis and Gene Expression Independently of Eukaryotic Initiation Factor 2 Phosphorylation in Mice [PDF]
Background: The phosphorylation of eukaryotic initiation factor 2 (p-eIF2) during dietary amino acid insufficiency reduces protein synthesis and alters gene expression via the integrated stress response (ISR).Objective: We explored whether a Met ...

Bacillus anthracis edema factor substrate specificity: evidence for new modes of action [PDF]
Since the isolation of Bacillus anthracis exotoxins in the 1960s, the detrimental activity of edema factor (EF) was considered as adenylyl cyclase activity only.

The role of the host—Neutrophil biology
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Alkyltransferase Ribozyme for Site‐Specific N4‐Cytidine Alkylation
CSAR is the first ribozyme that catalyzes direct alkylation of an exocyclic amino group of an RNA nucleobase. The ribozyme was isolated as a self‐labeling catalyst from an in vitro selection library and engineered into a trans‐active ribozyme that catalyzes the transfer of a benzyl group from an O6‐modifed guanine to the N4 amino group of a specific ...

Kalirin Interacts with TRAPP and Regulates Rab11 and Endosomal Recycling
Coordinated actions of Rab and Rho are necessary for numerous essential cellular processes ranging from vesicle budding to whole cell movement. How Rab and Rho are choreographed is poorly understood. Here, we report a protein complex comprised of kalirin,

Dbl oncogene expression in MCF-10 A epithelial cells disrupts mammary acinar architecture, induces EMT and angiogenic factor secretion. [PDF]
The proteins of the Dbl family are guanine nucleotide exchange factors (GEFs) of Rho GTPases and are known to be involved in cell growth regulation. Alterations of the normal function of these proteins lead to pathological processes such as developmental

EspM2 is a RhoA guanine nucleotide exchange factor [PDF]
We investigated how the type III secretion system WxxxE effectors EspM2 of enterohaemorrhagic Escherichia coli, which triggers stress fibre formation, and SifA of Salmonella enterica serovar Typhimurium, which is involved in intracellular survival, modulate Rho GTPases.
