Loss of function mutations of the type 2 vasopressin receptor (V2R) in kidney can lead to nephrogenic diabetes insipidus (NDI). We studied a previously described, but uncharacterized mutation of V2R (N321K missense mutation) ...

It was tested whether intrinsic CB1R activation modifies myogenic and agonist induced contraction of intramural coronary resistance arteries of the rat. CB1R protein was detected by immuno-histochemistry and by Western ...

Cells deficient in mitochondrial fusion have been shown to have defects linked to the exchange of inner membrane and matrix components. Because outer-mitochondrial membrane (OMM) constituents insert directly from the ...

G Protein Coupled Receptors (GPCR) can form dimers or higher ordered oligomers, the process of which can remarkably influence the physiological and pharmacological function of these receptors. Quantitative Bioluminescence ...

The role of the highly-conserved 'DRY' motif in the signaling of the CB1 cannabinoid receptor (CB1R) was investigated by introducing single, double and triple alanine mutations into this site of the receptor. We found that ...

Intracellular signaling systems of G protein-coupled receptors are well established, but their role in paracrine regulation of adjacent cells is generally considered as a tissue-specific mechanism. We have shown ...

Plasma membrane (PM) localization of Ras proteins is crucial for transmitting signals upon mitogen stimulation. Posttranslational lipid modification of Ras proteins plays an important role in their recruitment to the PM. ...

The cannabinoid CB1 receptor (CB1R) is,a G protein-coupled receptor, which couples to the G(i/o) family of heterotrimeric G proteins. The receptor displays both basal and agonist-induced signaling and internalization. ...
