Receptor oligomerization: from early evidence to current understanding in class B GPCRs [PDF]
Dimerization or oligomerization of G protein-coupled receptors (GPCRs) are known to modulate receptor functions in terms of ontogeny, ligand-oriented regulation, pharmacological diversity, signal transduction and internalization.

Parathyroid hormone receptors PTH1R and PTH2R are poorly studied in the pathology of the vertebral column and may be involved in both ectopic ossification of the vertebral ligaments and fibrous growth of the extracellular matrix, as well as in other ...

The Unicellular State as a Point Source in a Quantum Biological System. [PDF]
A point source is the central and most important point or place for any group of cohering phenomena. Evolutionary development presumes that biological processes are sequentially linked, but neither directed from, nor centralized within, any specific ...

Molecular Mechanisms of Parathyroid Disorders in Chronic Kidney Disease
Secondary hyperparathyroidism (SHP) is a common complication of chronic kidney disease (CKD) that induces morbidity and mortality in patients. How CKD stimulates the parathyroid to increase parathyroid hormone (PTH) secretion, gene expression and cell ...

Tctex-1 augments G protein-coupled receptor-mediated Gs signaling by activating adenylyl cyclase
Proteins interacting with G protein-coupled receptors (GPCRs) can modulate signal transduction of these receptors. However, the regulatory mechanisms of the interacting proteins are diverse and largely unknown.

Secretion of parathyroid hormone may be coupled to insulin secretion in humans
Objective: Parathyroid hormone (PTH) is a key hormone in regulation of calcium homeostasis and its secretion is regulated by calcium. Secretion of PTH is attenuated during intake of nutrients, but the underlying mechanism(s) are unknown.

Loss of receptor activity-modifying protein 2 in mice causes placental dysfunction and alters PTH1R regulation. [PDF]
Receptor activity-modifying protein 2 (Ramp2) is a single-pass transmembrane protein that heterodimerizes with several family B G-protein coupled receptors to alter their function.
