Entrez Gene Summary for FBN3 Gene

  • This gene encodes a protein that belongs to the fibrillin gene family. Fibrillins are extracellular matrix molecules that assemble into microfibrils in many connective tissues. This gene is most highly expressed in fetal tissues and its protein product is localized to extracellular microfibrils of developing skeletal elements, skin, lung, kidney, and skeletal muscle. This gene is potentially involved in Weill-Marchesani syndrome. While several transcript variants may exist for this gene, their full-length natures have not been described to date.

GeneCards Summary for FBN3 Gene

FBN3 (Fibrillin 3) is a Protein Coding gene. Diseases associated with FBN3 include weill-marchesani syndrome. Among its related pathways are ERK Signaling and ERK Signaling. GO annotations related to this gene include calcium ion binding and extracellular matrix structural constituent. An important paralog of this gene is NPNT.

UniProtKB/Swiss-Prot for FBN3 Gene

  • 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-containing microfibrils provide long-term force bearing structural support.
