Fibulin 1: Products

Fibulin 1 is a matricellular glycoprotein component of the elastic fiber core in connective tissues. It self-aggregates and additionally binds to several extracellular matrix and cellular proteins including Aggrecan, Versican, Fibronectin, ECM1, NOV/CCN3, and pro-HB-EGF. Fibulin 1c enhances ADAMTS-1 mediated cleavage of Aggrecan and Versican and can itself be cleaved by neutrophil elastase or MMP-13.

It functions as a bridge between Fibrinogen and Fibrin, enabling Fibrin attachment to the platelet cell surface via Integrin alpha 2 beta 3. Fibulin 1 inhibits cardiomyocyte proliferation and Fibronectin-mediated cell adhesion and can promote bone formation.
