  • Publication number: 20200131277
    Abstract: Presented herein are novel phosphotyrosine binding compositions, including antibodies and antibody fragments. The inventors of the present disclosure have resolved the crystal structures of two widely utilized pan-specific pY antibodies, PY20 and 4G10. These two known antibodies, although developed independently from animal immunizations, have surprisingly similar modes of recognition of the phosphate group, and revealed a generic binding structure among pan-specific pY antibodies. Based on this newly discovered convergent structure, engineered CDR-L3 loops were developed that impart greatly improved affinity to pY binding antibodies and other pY binding compositions. The inventions disclosed herein include antibodies and antibody fragments bearing these novel CDR-L3 sequences and methods of using such pY binding compositions for the detection of phosphotyrosine-bearing proteins.
