Abstract

Misfolding of membrane proteins plays an important role in many human diseases such as retinitis pigmentosa, heredity deafness and diabetes insipidus. Single molecule force spectroscopy is a novel technique which measures the force necessary to pull a protein out of a membrane. Such force distance curves contain valuable information on the proteins structure. High-throughput force spectroscopy experiments generate hundreds of curves. These curves are then evaluated and aligned to generate a two-dimensional plot of unfolding patterns representing the distribution of force and contour length through a Gaussian distribution.
