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 Degradation of the extracellular matrix. Gene Ontology (GO) annotations related to this gene include calcium ion binding and extracellular matrix binding. An important paralog of this gene is FBN2.

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).
