选择性识别和感知蛋白表面酪氨酸或丝氨酸/苏氨酸残基激酶催化磷酸化的工具对于理解活细胞的信号转导级联是必不可少的。RNA和肽(核糖核肽)的稳定复合物为小分子定制受体提供了方便的方法。在体外选择rna衍生的核糖核肽池,可以获得针对磷酸酪氨酸的核糖核肽受体。磷酸酪氨酸结合核糖核肽受体区分磷酸酪氨酸与酪氨酸、磷丝氨酸和磷苏氨酸。(DOI: 10.1380 / ejssnt.2005.33)
Tools for selective recognition and sensing of kinase-catalyzed phosphorylation at tyrosine or serine/threonine residues located on the protein surface are essential for understanding signal transduction cascades of living cell. A stable complex of RNA and peptide (ribonucleopeptide) provides a convenient approach to tailor a receptor for small molecules. In vitro selection of an RNA-derived pool of ribonucleopeptide afforded a ribonucleopeptide receptor specific for phosphotyrosine. The phosphotyrosine-binding ribonucleopeptide receptor discriminated phosphotyrosine against tyrosine, phosphoserine and phosphothreonine. [DOI: 10.1380/ejssnt.2005.33]
