Abstract: The application discloses a role of p62 in aging-related disease, such as development of obesity, type 2 diabetes mellitus, non-alcoholic fatty liver, various tumors, increased male mortality, intracellular inclusion named sequestosome, and redox regulation. In particular the application discloses a method of detecting the formation of inclusion bodies in neurodegenerative diseases. The invention further relates to a method of screening for therapeutic agents that disperse the inclusions. Further, transgenic mice containing a mutation in the p62 gene and having a functionally disrupted p62 gene locus are also disclosed.

Abstract: The present application discloses a method of determining whether an analyte binds to a target molecule in a sample comprising contacting the target molecule with a tracer molecule, wherein a bond is formed between the target molecule and the tracer molecule to form a target molecule/tracer molecule complex; contacting the target molecule/tracer molecule complex with the sample containing the analyte; and measuring fluorescence polarization of the tracer molecule over time to determine whether the analyte binds to the target molecule, wherein decreased fluorescence polarization over time indicates that the analyte binds to the target molecule, and wherein the reaction is conducted in the presence of a block copolymer surfactant.

Abstract: Isolated nucleic acid molecules encoding novel members of the p62 family of polypeptides which include, in preferred embodiment, an SH2 binding domain and a ubiquitin binding domain are described. Also disclosed are novel members of the p160 family of polypeptides. The p62 polypeptides and the p160 polypeptides of the invention are capable of modulating leukocyte activity, e.g., by stimulating a B cell response, including B cell proliferation, B cell aggregation, B cell differentiation, B cell survival, and/or stimulating a T cell response, e.g., T cell proliferation, T cell aggregation, T cell differentiation, and T cell survival, are disclosed. The p62 polypeptides and the p160 polypeptides of the invention are also capable of modulating ubiquitin-mediated degradation of cellular proteins.
