Research Description

Think about how versatile a human muscle cell must be- it has to have the structural integrity to withstand strong forces, yet must be pliable enough to bend and stretch repeatedly without breaking.  Muscles accomplish this contrasting need for strength and motion through a complex lattice of proteins and membranes.  Obscurin, a large protein discovered within the past decade, helps in this feat by linking the muscle contractile apparatus with various cell membranes. This large, highly modular protein is made up of at least 71 discrete domains.  Most of these domains act as either adhesion points for other structural molecules, signaling moieties, or linker regions. Additionally, the protein contains elements that sense stretch, and can promote muscle repair.  Likewise, mutations in these domains are linked to muscle diseases such as cardiomyopathy and several muscular dystrophies.  My lab is focused on studying the structure of the individual domains of obscurin and obscurin-binding partners.  This will help determine the cellular and molecular mechanism of how obscurin performs its job with atomic-scale resolution.  To do this, students in Dr. Wright’s lab with use a variety of structural biochemistry techniques including protein x-ray crystallography and multidimensional heteronuclear NMR analysis.  Insight gained from these studies will allow both better understanding of the molecular basis of human muscle diseases, and potentially novel ways to treat these diseases.
