    摘要: The present invention provides a method of cleaving a recombinantly expressed protein from an intein and ligating the protein to a peptide containing an N-terminal cysteine having an unoxidized sulfhydryl side chain which comprises contacting the protein with the peptide in a reaction solution comprising a conjugated thiophenol, thereby forming a C-terminal thioester of the recombinant protein which spontaneously rearranges intramolecularly to form an amide bond linking the protein to the peptide. The present invention also provides a method of producing a protein-chip composition comprising the steps of: (a) contacting a solid support chip containing an amine group with a peptide containing an N-terminal cysteine having an unoxidized sulfhydryl side chain thereby covalently linking the peptide to the solid support, forming a peptide-chip; and (b) contacting a recombinant protein having an intein domain with the peptide-chip of step (a) with a reaction solution containing a conjugated thiophenol, thereby forming a C-terminal thioester of the recombinant protein which spontaneously rearranges intramoleculaly to form an amide bond covalently linking the protein to the peptide-chip, thereby producing a protein-chip composition.

    摘要: Protein kinase inhibitors have applications as anti-cancer therapeutic agents and biological tools in cell signalling. Potent and selective bisubstrate inhibitors for the insulin receptor tyrosine kinase are based on a phosphoryl transfer mechanism involving a dissociative transition state. One such inhibitor is synthesized by linking ATPγS to a peptide substrate analog via a two-carbon spacer. The compound is a high-affinity competitive inhibitor against both nucleotide and peptide substrate and shows a slow off-rate. A crystal structure of this inhibitor bound to the tyrosine kinase domain of the insulin receptor confirms the key design features inspired by a dissociative transition state, and reveal that the linker takes part in the octahedral coordination of an active site Mg2+ ion.

    摘要: Methods for treating or preventing a Foxp3+ T regulatory cell (Treg) related disease in a subject in need thereof comprise administering to the subject an effective amount of a pharmaceutical composition comprising an inhibitor of a histone/protein acetyltransferase (HAT). Methods for identifying an agent useful for treating or preventing a Foxp3+ T regulatory cell (Treg) related disease comprise (a) contacting a candidate agent with a test sample comprising Foxp3+ T regulatory cells (Tregs), and (b) comparing a function of the Foxp3+ Tregs in the test sample with that in a control sample, wherein inhibition of the function of the Foxp3+ Tregs in the test sample when compared with the control sample indicates that the candidate agent is an agent useful for treating or preventing a Foxp3+ Treg related disease.
