Fibulin 1 is a secreted glycoprotein that becomes incorporated into a fibrillar extracellular matrix. Calcium-binding is apparently required to mediate its binding to laminin and nidogen. It mediates platelet adhesion via binding fibrinogen. Four splice variants which differ in the 3' end have been identified. Each variant encodes a different isoform, but no functional distinctions have been identified among the four variants. [provided by RefSeq, Jul 2008]
Forensic Context
A study in human blood plasma from 103 individuals demonstrated that the protein FBLN1 (Fibulin-1) was significantly upregulated with age and was associated with diabetes, impaired kidney function, and cardiovascular risk markers [Salignon et al. DOI:10.18632/aging.204787].
