Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION 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.FUNCTION Hormone secreted by trophoblasts that promotes trophoblast invasiveness (PubMed:32329225). Has glucogenic activity: is able to increase plasma glucose levels (By similarity).SUBUNIT Interacts with BMP2, BMP4, BMP7, BMP10 and GDF5 (PubMed:18339631). Interacts with MFAP2 and MFAP5 (PubMed:15131124). Interacts with ADAMTSL5 (PubMed:23010571). Interacts with MFAP4 (PubMed:26601954).INTERACTION Fibrillin-2 and Placensin chains are still linked together during the secretion from cells, but are subsequently separated by furin.SUBCELLULAR LOCATION Secreted by placental cells.ALTERNATIVE PRODUCTS Almost exclusively expressed in placenta (PubMed:32329225). Expressed at much lower level in other tissues (PubMed:32329225). Expressed in fetal eye (18 weeks)in the retinal pigment epithelium (RPE), the choroid, Bruch's membrane and in the sclera (PubMed:24899048). Not expressed in the neural retina (PubMed:24899048).TISSUE SPECIFICITY Present at high level in cytotrophoblasts as compared with syncytiotrophoblasts at 8-9 weeks of pregnancy (at protein level) (PubMed:32329225). Levels in the serum increase during pregnancy (at protein level) (PubMed:32329225).PTM N-glycosylated.PTM O-glycosylated on serine residues by POGLUT2 and POGLUT3.DISEASE The disease is caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the fibrillin family.
