Method of determining inhibition of binding to TRPM7 protein
First Claim
Patent Images
1. A method for determining whether a test compound inhibits binding between a TRPM7 protein and a PDZ domain-containing polypeptide, comprising:
- (i) contacting a TRPM7 protein or a fragment thereof containing at least the four C-terminal amino acids of the protein with a PDZ domain-containing polypeptide in the presence and absence of the test compound; and
(ii) measuring the amount of complex formed between the TRPM7 protein or fragment thereof and the PDZ domain-containing polypeptide in the presence and absence of the test compound,wherein less complex is formed in the presence relative to the absence of the test compound indicating the test compound is an inhibitor of binding between the TRPM7 protein and the PDZ domain-containing polypeptide.

Abstract
This invention relates to methods of reducing the damaging effect of an injury to mammalian cells by treatment with compounds which reduce cell death or dysfunction, including cellular damage following episodes of tissue ischemia, trauma, epilepsy, and acute or chronic degeneration. The invention discloses methods of treating these disorders by administering inhibitors that disrupt protein-protein interactions involved in these disorders, screening methods to identify such inhibitors and specific compositions useful for treating these disorders.
