The invention provides methods and compositions relating to a novel kinase designated PAS Kinase (PASK). The compositions include isolated polypeptides comprising a native PASK protein or a PASK N-terminal domain and polypeptides consisting of a PASK PAS-A or PAS-B domain, as well as isolated polynucleotides encoding such polypeptides, and expression vectors and cells comprising such polynucleotides. The methods include binding assays comprising the steps of incubating a mixture comprising a subject polypeptide with a ligand under conditions wherein the polypeptide binds the ligand; and detecting binding of the polypeptide to the ligand.

Specific binding of a foreign core ligand to a PAS domain, wherein the PAS domain is predetermined, prefolded in its native state, and comprises a hydrophobic core that has no NMR-apparent a priori formed ligand cavity, is determined by (a) detecting a first NMR spectrum of the PAS domain in the presence of a foreign ligand; and (b) comparing the first NMR spectrum with a second NMR spectrum of the PAS domain in the absence of the ligand to infer the presence the ligand specifically bound within the hydrophobic core of the PAS domain. A functional surface binding specificity of a PAS domain, wherein the PAS domain is predetermined, prefolded in its native state, and comprises a hydrophobic core that has no NMR-apparent a priori formed ligand cavity, is changed by (a) introducing into the hydrophobic core of the PAS domain a foreign ligand of the PAS domain; and (b) detecting a change in the functional surface binding specificity of the PAS domain.

US Classification:
435 61, 436 94, 4353201
Abstract:
The present invention provides methods, compositions, and kits associated with succinate dehydrogenase-related disease conditions. In one aspect of the present invention, a method for screening a test subject to determine risk for developing a succinate dehydrogenase-related disease condition is provided. Such a method can include obtaining a biological sample from the test subject and identifying a mutation in gene hSDH5 from the biological sample of the test subject, wherein the mutation effectuates a decreased level of succinate dehydrogenase flavination in the test subject as compared to a level of succinate dehydrogenase flavination in a normal subject. In one aspect, the mutation is at hSDH5 Gly78 of gene hSDH5. In another aspect, the mutation is equivalent to an hSDH5 Gly78Arg substitution of gene hSDH5.
