Microfibrillar associated protein 5
MAGP-2, Microfibril-associated glycoprotein-2
This gene encodes a 25-kD microfibril-associated glycoprotein which is rich in serine and threonine residues. It lacks a hydrophobic carboxyl terminus and proline-, glutamine-, and tyrosine-rich regions, which are characteristics of a related 31-kDa microfibril-associated glycoprotein (MFAP2). The close similarity between these two proteins is confined to a central region of 60 aa where precise alignment of 7 cysteine residues occurs. The structural differences suggest that this encoded protein has some functions that are distinct from those of MFAP2. [provided by RefSeq, Jul 2008] (from

Microfibril-associated glycoprotein 2 (MAGP2) is a secreted protein associated with multiple cellular activities including the organization of elastic fibers in the extracellular matrix (ECM), angiogenesis, as well as regulating Notch and integrin signaling.

Previous studies have suggested that fibrillin 1 mediates skin fibrosis via its interface with associated microfibrillar proteins and type I collagen; in particular, microfibril-associated glycoprotein 2 (MAGP-2), an extracellular matrix protein that binds to fibrillins and the alphavbeta3 integrin, is increased in TSK mouse and human scleroderma skin.

Although fibrillins and MAGPs covalently associate, we find that the DSL (Delta/Serrate/LAG2) protein Jagged1, an activating ligand for Notch receptor signaling, also interacts with MAGP-2 in both yeast two-hybrid and coimmunoprecipitation studies.

results show MAGP-2 is covalently and periodically located along the fibrillin-containing microfibrils of the developing nuchal ligament, suggesting that it is an integral component of most if not all of the microfibrils in this elastic fiber-rich tissue
