Sci. STKE, 29 May 2007 PERSPECTIVESParsing the Motion of Single Molecules: A Novel Algorithm for Deconvoluting the Dynamics of Individual Receptors at the Cell SurfaceIndraneel Ghosh* and Mary J. Wirth* Department of Chemistry, University of Arizona, Tucson, AZ 85721, USA. Abstract:
To truly understand signal transduction, we will ultimately need to understand the dynamics and kinetics of individual proteins as they perform their functions in a single cell. Groundbreaking advances in single-molecule biophysics now allow us to follow the motion of many individual proteins on the cell surface with the use of fluorescent probes, such as quantum dots. However, discriminating the directed movement of single molecules from their natural Brownian motion remains a challenge. A recent paper provides a powerful statistical approach for distinguishing periods of directed motion of individual *Corresponding authors.
