VPS35: Two Ways to Recycle the Parathyroid Hormone Receptor (PTH1R) in Osteoblasts

The recombinant parathyroid hormone (PTH) Teriparatide is the only therapy for postmenopausal osteoporosis that increases bone mass (i.e., is anabolic). Its therapeutic action depends on a short “burst” of PTH in the circulation followed by a rapid return to normal levels; if PTH levels remain high, bone loss occurs (i.e., the effect is catabolic) (Frolik et al., 2003). This occurs because PTH ...

Nuclear cytoplasmic shuttling by thyroid hormone receptors. multiple protein interactions are required for nuclear retention.

In this report, we have studied the intracellular dynamics and distribution of the thyroid hormone receptor-beta (TRbeta) in living cells, utilizing fusions to the green fluorescent protein. Wild-type TRbeta was mostly nuclear in both the absence and presence of triiodothyronine; however, triiodothyronine induced a nuclear reorganization of TRbeta. By mutating defined regions of TRbeta, we foun...

Bovine parathyroid hormone enhances osteoclast bone resorption by modulating V-ATPase through PTH1R

The vacuolar-type H+ adenosine triphosphatase (V-ATPase) plays an important role in cellular acidification and bone resorption by osteoclasts. However, the direct effect of bovine parathyroid hormone (bPTH) on V-ATPase has not yet been elucidated. The aim of the present study was to assess the effects of bPTH on V-ATPase and osteoclasts. Osteoclasts from bone marrow (BM)-derived monocytes of C5...

NHERF1 regulates parathyroid hormone receptor desensitization: interference with beta-arrestin binding.

Type 1 parathyroid hormone receptor (PTH1R) activation, desensitization, internalization, and recycling proceed in a cyclical manner. The Na(+)/H(+) exchange regulatory factor 1 (NHERF1) is a cytoplasmic adapter protein that regulates trafficking and signaling of several G protein-coupled receptors (GPCRs) including the PTH1R. The mineral ion wasting and bone phenotype of NHERF1-null mice sugge...

Nuclear-Cytoplasmic Trafficking of NTF2, the Nuclear Import Receptor for the RanGTPase, Is Subjected to Regulation

NTF2 is a cytosolic protein responsible for nuclear import of Ran, a small Ras-like GTPase involved in a number of critical cellular processes, including cell cycle regulation, chromatin organization during mitosis, reformation of the nuclear envelope following mitosis, and controlling the directionality of nucleocytoplasmic transport. Herein, we provide evidence for the first time that translo...
