Hemicentins share a single, highly conserved amino-terminal von Willebrand A domain, followed by a long (〉40) stretch of immunoglobulin repeats, multiple tandem epidermal growth factors and a fibulin-like carboxy-terminal module. C. elegans has a single hemicentin gene that has pleiotropic functions in transient cell contacts that are required for cell migration and basement membrane invasion and in stable contacts at hemidesmosome-mediated cell junctions and elastic fiber-like structures.
