NX_Q9BQB4 - SOST - Sclerostin - Function. Negative regulator of bone growth that acts through inhibition of Wnt signaling and bone formation. Humans lacking sclerostin display progressive bone over-growth due to increased bone formation. Although it is well is crucial to mediate the inhibitory function of sclerostin on Wnt1/ -catenin signaling and on bone formation.
Similarly, mice with breast cancer–induced metastatic bone disease have a reduced ex vivo muscle contractility compared with healthy animals ( Figure 4A ) ( 17 ). In this review, we discuss the biology of Wnt signaling and sclerostin inhibition. We then discuss human disorders of decreased sclerostin function and animal models of sclerostin inhibition. Both have served to elucidate the effects of decreased sclerostin levels and function – increased bone mass and strength and fewer fractures. 2011-10-04 · Sclerostin is a product of mature osteocytes embedded in mineralised bone and is a negative regulator of bone mass and osteoblast differentiation. While evidence suggests that sclerostin has an anti-anabolic role, the possibility also exists that sclerostin has catabolic activity. To test this we treated human primary pre-osteocyte cultures, cells we have found are exquisitely sensitive to View protein in InterPro IPR029034, Cystine-knot_cytokine IPR008835, Sclerostin/SOSTDC1 IPR015665 PANTHER i PTHR14903 , PTHR14903, 1 hit PTHR14903:SF4 , PTHR14903:SF4, Sclerostin antibodies in osteoporosis: latest evidence and therapeutic potential Michael R. McClung Abstract: Sclerostin is an osteocyte-derived glycoprotein that inhibits Wnt/β-catenin signaling and activation of osteoblast function, thereby inhibiting bone formation.

Sclerostin is produced in osteocytes, which are a type of bone cell. The main function of sclerostin is to stop (inhibit) bone formation. The maintenance of bone over time requires a balance between the formation of new bone tissue and the breakdown and removal (resorption) of old bone tissue. Genetic studies in humans and mice have shown that the secreted protein sclerostin is a key negative regulator of bone formation, although the magnitude and extent of sclerostin's role in the control of bone formation in the aging skeleton is still unclear. 2020-11-18 · Sclerostin is highly expressed by osteocytes, negatively regulates canonical Wnt signaling pathways by binding to low-density lipoprotein receptor-related protein (LRP) 5/6, and suppresses osteoblast differentiation and/or function. Sclerostin, the product of the SOST gene, is a secreted inhibitor of Wnt signaling that is produced by osteocytes to regulate bone formation.
However, Thouverey and Caverzasio found that sclerostin not only functions by inhibiting canonical Wnt signaling, but also activates platelet-derived growth factor receptor signaling to inhibit osteoblast di erentiation [23].

(2003) found that recombinant human sclerostin bound BMP2, BMP4, BMP5 ( 112265 ), BMP6, and BMP7 in vitro with similar binding kinetics and affinities. Sclerostin is an osteocyte derived protein that inhibits bone formation. Antagonizing its function is a potential therapeutic strategy to increase high quality bone. Our studies will allow an atomic-level understanding of the interface between sclerostin and three protein partners that mediate sclerostin function. complete loss of function of sclerostin and thus to the characteristic sclerosteosis phenotype.

However, since sclerostin was subsequently shown not to inhibit early BMP‐induced responses in vitro, it was suggested that it might act by modulating Wnt signaling ( 9 ). 2021-03-29 · Sclerostin (gene name Sost) is a secreted 27 kDa glycoprotein that inhibits the differentiation and activity of bone-forming osteoblasts by antagonizing the Wnt/β-catenin signaling pathway (Baron and Gori, 2018; Drake and Khosla, 2017).
