Entrez Gene Summary for FBLN2 Gene

  • This gene encodes an extracellular matrix protein, which belongs to the fibulin family. This protein binds various extracellular ligands and calcium. It may play a role during organ development, in particular, during the differentiation of heart, skeletal and neuronal structures. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

GeneCards Summary for FBLN2 Gene

FBLN2 (Fibulin 2) is a Protein Coding gene. Diseases associated with FBLN2 include Familial Osteochondritis Dissecans and Osteochondritis Dissecans. Among its related pathways are Elastic fibre formation and Cell adhesion_Cell-matrix glycoconjugates. GO annotations related to this gene include calcium ion binding and extracellular matrix binding. An important paralog of this gene is FBN3.

UniProtKB/Swiss-Prot for FBLN2 Gene

  • Its binding to fibronectin and some other ligands is calcium dependent. May act as an adapter that mediates the interaction between FBN1 and ELN (PubMed:17255108).
