Gain of function mutants: Ion channels and G protein-coupled receptors [PDF]
, 2000 Many ion channels and receptors display striking phenotypes for gain-of-function mutations but milder phenotypes for null mutations. Gain of molecular function can have several mechanistic bases: selectivity changes, gating changes including constitutive

Interaction of Prokineticin Receptors with Accessory Proteins
Encyclopedia, 2023 G protein-coupled receptors (GPCRs) are transmembrane proteins that mediate the intracellular pathway of signals not only through heterotrimeric GTP-binding proteins (G proteins) but also through their associations with a variety of additional partner ...

Regulators of G protein signalling proteins in the human myometrium [PDF]
, 2009 The contractile state of the human myometrium is controlled by extracellular signals that promote relaxation or contraction. Many of these signals function through G proteincoupled receptors at the cell surface, stimulating heterotrimeric G proteins and ...

GPCRs in Intracellular Compartments: New Targets for Drug Discovery
Biomolecules, 2022 The architecture of eukaryotic cells is defined by extensive membrane-delimited compartments, which entails separate metabolic processes that would otherwise interfere with each other, leading to functional differences between cells.

G-protein-coupled receptor kinases
Trends in Biochemical Sciences, 1991 Rhodopsin kinase and the beta-adrenergic receptor kinase (beta ARK) catalyse the phosphorylation of the activated forms of the G-protein-coupled receptors, rhodopsin and the beta 2-adrenergic receptor (beta 2AR), respectively. The interaction between receptor and kinase is independent of second messengers and appears to involve a multipoint attachment ...

Lysophosphatidic Acid Signaling in Cancer Cells: What Makes LPA So Special?
Cells, 2021 Lysophosphatidic acid (LPA) refers to a family of simple phospholipids that act as ligands for G protein-coupled receptors. While LPA exerts effects throughout the body in normal physiological circumstances, its pathological role in cancer is of great ...
