The protein BigH3 is a cell-adhesion molecule induced by transforming growth factor-β (TGF-β). It consists of four homologous repeat domains known as FAS1 domains; mutations in these domains have been linked to corneal dystrophy. The fourth FAS1 domain was expressed in Escherichia coli B834 (DE3) (a methionine auxotroph) and purified by DEAE anion-exchange and gel-filtration chromatography. The FAS1 domain was crystallized using the vapour-diffusion method. A SAD diffraction data set was collected to a resolution of 2.5 Å at 100 K. The crystal belonged to space group P61 or P65 and had two molecules per asymmetric unit, with unit-cell parameters a = b = 62.93, c = 143.27 Å, α = β = 90.0, γ = 120.0°.
