Parathyroid hormone without parathyroid glands.
In mammals, PTH is a component in a complex signaling system involving three structurally related ligands and two G protein-coupled receptors, which share significant amino acid sequence homology (Fig. 1). PTH is a peptide hormone comprising 84 amino acids that is made by the parathyroid glands (and to a much smaller extend by the thymus) and acts through the PTH/PTH-related peptide (PTHrP) rec...
متن کاملPTHLH (parathyroid hormone-like hormone)
DNA/RNA Description PTHLP is encoded by a single gene that is highly conserved among species. The gene is composed of 7 exons spanning a region of 13,899 bases (Start: 28,002,284 bp from pter; End: 28,016,183 bp from pter). Orientation: minus strand. The genomic DNA for the PTHLP gene was isolated from a human placental genomic library. Transcription The sequence is supported by 3 sequences fro...
متن کاملSignalling from parathyroid hormone.
PTH (parathyroid hormone), acting via type 1 PTH receptors, is a major regulator of plasma [Ca(2+)]. The G-protein, G(s), is an essential component of the sequence linking PTH to plasma Ca(2+) regulation, but the relative importance of intracellular signals, including Ca(2+) and cAMP, that lie downstream of G(s) is not resolved.
متن کاملUnderstanding parathyroid hormone action.
In addition to regulating serum calcium and stimulating bone resorption, parathyroid hormone (PTH) is known to stimulate bone formation under certain conditions. The mechanisms behind this counterintuitive anabolic action are largely unknown. We have set out to identify PTH-regulated genes that might be responsible for each of these contrasting effects of the hormone. This article describes our...
متن کاملExpression of parathyroid hormone-related protein and the parathyroid hormone/parathyroid hormone-related protein receptor in rat thymic epithelial cells.
Thymic epithelial cells are an important source of cytokines and other regulatory peptides which guide thymocyte proliferation and maturation. Parathyroid hormone-related protein (PTHrP), a cytokine-like peptide, has been reported to affect the proliferation of lymphocytes in vitro. The studies presented here were undertaken to test the hypotheses that PTHrP is produced locally within the thymu...
