RESUMEN
Protein phosphorylation is one of the most common post-translational modifications (PTMs)in various organisms,which plays critical roles in the regulation of intracellular biological processes,such as cell prolifera-tion,signal transduction,metabolismis and tumorigenesis.However,the low abundance of phosphoprotein in the biological systems poses significant challenges of current analytical techniques.In order to further understand the phosphoproteomics,the roles of phosphorylated proteins in life process,discovery of biomarkers,diagnosis and treatment of disease,enrichment strategies of high efficiency have been developed,including the design of new nanomaterials and combination of a variety of analytical methods,et al.In this paper,we reviewed the develop-ment of enrichment strategies for phosphoproteomics and application of phosphoproteomics in disease.
