General annotation (Comments)

Function	Neuroendocrine peptide which is a critical regulator of cellular and organ growth, development, migration, differentiation and survival and of epithelial calcium ion transport. Regulates endochondral bone development and epithelial-mesenchymal interactions during the formation of the mammary glands and teeth. Required for skeletal homeostasis. Promotes mammary mesenchyme differentiation and bud outgrowth by modulating mesenchymal cell responsiveness to BMPs. Upregulates BMPR1A expression in the mammary mesenchyme and this increases the sensitivity of these cells to BMPs and allows them to respond to BMP4 in a paracrine and/or autocrine fashion. BMP4 signaling in the mesenchyme, in turn, triggers epithelial outgrowth and augments MSX2 expression, which causes the mammary mesenchyme to inhibit hair follicle formation within the nipple sheath By similarity. Osteostatin is a potent inhibitor of osteoclastic bone resorption By similarity.
Subunit structure	PTHrP interacts with PTH1R (via N-terminal extracellular domain) By similarity.
Subcellular location	Cytoplasm By similarity. Nucleus By similarity. Secreted By similarity.
Post-translational modification	There are several secretory forms, including osteostatin, arising from endoproteolytic cleavage of the initial translation product. Each of these secretory forms is believed to have one or more of its own receptors that mediates the normal paracrine, autocrine and endocrine actions By similarity.
Sequence similarities	Belongs to the parathyroid hormone family.
