- Fibulin 5, also known as DANCE and EVEC, is a secreted 55kD matricellular glycoprotein that plays an important role in elastic fiber network assembly and angiogenesis. Mature human Fibulin 5 contains an N-terminal EGF-like domain with an RGD motif, a 44aa spacer region, five more tandem EGF-like domains, and a 115aa Fibulin-like C-terminal region. Mature human Fibulin 5 shares 95% aa sequence identity with mouse and rat Fibulin 5. Fibulin 5 i s expressed by smooth muscle cells and endothelial cells of the developing asculature as well as by migrating neural crest cells and l unginterstitial fibroblasts. It is downregulated in the adult vasculature but is re-expressed at aortic branching points, in the uterus, and at sites of mechanical or at herosclerotic injury. The RGD motif of Fibulin 5 binds to several cell surface Integrins including aVb3, aVb5, a9b1, a4b1, and a5b1. The calcium-dependent binding of Fibulin 5 to elastic fibers serves to anchor cells to the extracellular matrix. Fibulin 5 promotes elastic fiber assembly and maturation by organizing Tropoelastin, LTBP-2, and the crosslinking lysyl oxidase-like enzymes LOXL1, 2, and 4 along Fibrillin microfibrils. In aged mice with decreased tissue elasticity, proteolytic removal of the N-terminal EGF-like domain prevent s Fibulin 5 from interacting with Fibrillin-1 microfibrils. Fibulin 5 functions as an angiogenesis inhibitor by inhibiting vascular smooth muscle proliferation a migration and by limiting vascular sprouting. Fibulin 5 is downregulated in many malignancies. When experimentally re-expressed, however, Fibulin 5 enhances tumor cell invasiveness and cooperates with TGF-b i n initiating and promoting epithelial-mesenchymal transition (EMT). Defects in Fibulin 5 expression or function can result in a loss of connective tissue Integrity, cardiac elasticity, and ability to remodel the vasculature after injury.
