Summary: A family of extracellular matrix glycoproteins that is structurally similar to LATENT TGF-BETA BINDING PROTEINS, but contain additional TGF-beta binding domains, in addition to unique domains at their N and C-terminals. Fibrillins assemble into 10-12 nm MICROFIBRILS that function in a variety of cell interactions with the EXTRACELLULAR MATRIX and developmental processes such as ELASTIC TISSUE maintenance and assembly, and the targeting of growth factors to the extracellular matrix.
