The invention provides reagents and methods for characterizing (i.e., identification and/or quantitation) the phosphorylation states of proteins. Proteins may be post-transcriptionally modified such that they contain phosphate groups at either some or all of their serine, threonine, tyrosine, histidine, and/or lysine amino acid residues. In many cases the extent to which a protein is phosphorylated determines it bioactivity, i.e., its ability to effect cell functions such as differentiation, division, and metabolism. Hence, a powerful tool for diagnosing various diseases and for furthering the understanding of protein-protein interactions is provided.
本发明提供了表征(即鉴定和/或定量)蛋白质磷酸化状态的试剂和方法。蛋白质可能经过转录后修饰,使其部分或全部丝氨酸、苏氨酸、酪氨酸、组氨酸和/或赖氨酸氨基酸残基含有磷酸基团。在许多情况下,蛋白质的磷酸化程度决定了其生物活性,即影响细胞功能(如分化、分裂和新陈代谢)的能力。因此,它为诊断各种疾病和进一步了解蛋白质与蛋白质之间的相互作用提供了强有力的工具。
