Abstract
The secreted cystine-knot protein sclerostin was first identified from genetic screening of patients suffering from the rare bone-overgrowth diseases sclerosteosis and van Buchem disease. Sclerostin acts a negative regulator of bone growth through inhibiting the canonical Wnt signalling cascade by binding to and blocking the Wnt co-receptor LRP5/6. Its function in blocking osteoblastogenesis makes it an important target for osteoanabolic therapy approaches to treat osteoporosis, which is characterized by a progressive decrease in bone mass and density. In this work, the production, crystallization and preliminary X-ray diffraction data analysis of a sclerostin-neutralizing human Fab antibody fragment, AbD09097, obtained from a naive antibody library are reported. Crystals of the Fab AbD09097 belonged to space group P21, with unit-cell parameters a = 45.19, b = 78.49, c = 59.20 Å, β = 95.71° and diffracted X-rays to a resolution of 1.8 Å.
