Muscarinic receptor oligomerization
G protein-coupled receptors (GPCRs) have been classically described as monomeric entities that function by binding in a 1:1 stoichiometric ratio to both ligand and downstream signalling proteins. However, in recent years, a growing number of studies has supported the hypothesis that these receptors can interact to form dimers and higher order oligomers although the molecular basis for these int...
متن کاملOligomerization of the cardiac ryanodine receptor C-terminal tail.
The C-terminal 100 amino acids of the RyR (ryanodine receptor), referred to as the C-terminal tail, is a highly conserved sequence that is present in all known RyR isoforms and which has been implicated in channel function. Deleting the final 15 amino acids from the full-length skeletal muscle RyR resulted in an inactive channel, attributed to impaired assembly of a tetrameric RyR complex [Gao,...
متن کاملStochastic models of receptor oligomerization by bivalent ligand.
In this paper, we develop stochastic models of receptor binding by a bivalent ligand. A detailed kinetic study allows us to analyse the role of cross-linking in cell activation by receptor oligomerization. We show how oligomer formation could act to buffer intracellular signalling against stochastic fluctuations. In addition, we put forward the hypothesis that formation of long linear oligomers...
متن کاملG protein-coupled receptor oligomerization revisited: functional and pharmacological perspectives.
Most evidence indicates that, as for family C G protein-coupled receptors (GPCRs), family A GPCRs form homo- and heteromers. Homodimers seem to be a predominant species, with potential dynamic formation of higher-order oligomers, particularly tetramers. Although monomeric GPCRs can activate G proteins, the pentameric structure constituted by one GPCR homodimer and one heterotrimeric G protein m...
متن کاملOligomerization and Endocytosis of the α-Factor Receptor: A Dissertation
Factor receptors from Saccharomyces cerevisiae are G-protein-coupled receptors containing seven transmembrane segments. The abilty of a-factor receptors to form oligomeric complexes with each other and with other proteins was investigated. Both in vivo and in vitro evidence was obtained that suggests homo-oligomerization of receptors in the plasma membrane. When the membranes from cells coexpre...
