Abstract

Parathyroid hormone-related protein (PTHrP; gene name PTHLH/Pthlh) acts as a paracrine/autocrine factor to produce a range of effects, including contributing to skeletal development and determining trabecular bone mass. By activating the receptor (PTH1R) that PTHrP shares with parathyroid hormone (PTH), it transduces cascades coupled with the stimulation of cyclic adenosine monophosphate (cAMP) protein kinase A (PKA) and CREB responses. However, in addition to its amino-terminal region that mediates similar actions to PTH, PTHrP has structural features that allow it to exert different activities independent of PTH1R. Relatively little is known about the signalling pathways that guide these a..
