Publication number: 20220380456Abstract: The present invention relates to the field of structural biology. More specifically, the present invention relates to an antigen-binding chimeric protein, called a MegaBody™, specifically binding a nanodisc, more specifically a membrane-scaffold protein (MSP)n which may be part of the nanodisc. The invention further provides for methods and uses of said nanodisc-specific antigen-binding chimeric proteins in three-dimensional high-resolution structural analysis of membrane proteins assembled within nanodiscs.

The agent may induces clustering of RPTP? and/or inhibit binding of chondroitin sulfate proteoglycan (CSPG) to RPTP?. Examples of suitable agents are heparan sulfate proteoglycan, heparan sulfate, heparan sulfate oligosaccharides, or heparin oligosaccharides. Additional agents are also disclosed. The neuron can be a CNS neuron or peripheral neuron. Also disclosed herein are methods of treating neuronal injury in a subject comprising, administering to the subject an agent that binds RPTP?. Administration may be to a site of neuronal injury, to thereby induce neuronal outgrowth at the site of neuronal injury.Type: GrantFiled: February 17, 2012Date of Patent: August 29, 2017Assignees: PRESIDENT AND FELLOWS OF HARVARD COLLEGE, THE CHANCELLOR, MASTERS AND SCHOLARS OF THE UNIVERSITY OF OXFORDInventors: John G.
