PHOSPHOTYROSINE ASSAY AND PEPTIDES FOR USE THEREIN

摘要

This invention relates to an assay for molecules capable of interacting with cytokine receptor intracellular peptides, and to peptides suitable for use in said assay. The peptides correspond to tyrosine-containing regions of the sequence of an intracellular domain of a cytokine, a hormone receptor or a JAK Protein Tyrosine Kinase, and comprise a tyrosine which is able to be phosphorylated. In phosphorylated form, the peptides are able to bind cytoplasmic transcription factors of the STAT family.
