Further evidence supporting a role for gs signal transduction in severe malaria pathogenesis.
With the functional demonstration of a role in erythrocyte invasion by Plasmodium falciparum parasites, implications in the aetiology of common conditions that prevail in individuals of African origin, and a wealth of pharmacological knowledge, the ...

Persistent activation of the α subunit of Gs promotes its removal from the plasma membrane [PDF]
As assessed both by cholera-toxin-catalysed ADP-ribosylation and by immunoblotting with an anti-peptide antiserum raised against the C-terminal decapeptide of forms of Gs alpha (the alpha subunit of the stimulatory guanine nucleotide-binding protein), rat glioma C6 BU1 cells express two forms of Gs alpha: a major 44 kDa form and a much less prevalent ...

New mutations at the imprinted Gnas cluster show gene dosage effects of Gsα in postnatal growth and implicate XLαs in bone and fat metabolism, but not in suckling [PDF]
The imprinted Gnas cluster is involved in obesity, energy metabolism, feeding behavior, and viability. Relative contribution of paternally expressed proteins XLαs, XLN1, and ALEX or a double dose of maternally expressed Gsα to phenotype has not been ...

The Pathogenic TSH β-Subunit Variant C105Vfs114X Causes a Modified Signaling Profile at TSHR [PDF]
1) Background: Central congenital hypothyroidism (CCH) is a rare endocrine disorder that can be caused by mutations in the β-subunit of thyrotropin (TSHB).

ER/K linked GPCR-G protein fusions systematically modulate second messenger response in cells. [PDF]
FRET and BRET approaches are well established for detecting ligand induced GPCR-G protein interactions in cells. Currently, FRET/BRET assays rely on co-expression of GPCR and G protein, and hence depend on the stoichiometry and expression levels of the ...
