[Fibrillin-2]: Fibrillins are structural components of 10-12 nm extracellular calcium-binding microfibrils, which occur either in association with elastin or in elastin-free bundles. Fibrillin-2- containing microfibrils regulate the early process of elastic fiber assembly. Regulates osteoblast maturation by controlling TGF-beta bioavailability and calibrating TGF-beta and BMP levels, respectively. . [Placensin]: Hormone secreted by trophoblasts that promotes trophoblast invasiveness (PubMed:32329225). Has glucogenic activity: is able to increase plasma glucose levels (By similarity). . This is the function of FBN2 (fibrillin 2, Ensembl gene identifier ENSG00000138829).
