    • A method for identifying a compound expected to be useful in modulating, for example inhibiting, LRRK2 protein kinase activity, the method comprising the steps of (1) determining whether a test compound modulates, for example inhibits, the protein kinase activity of a LRRK2 polypeptide on a substrate polypeptide and (2) selecting a compound which modulates, for example inhibits, the said LRRK2 polypeptide protein kinase activity, wherein the substrate polypeptide comprises the sequence (W/F/R/K)(W/F/R/K)(R/K)(F/W/H/R)(Y/W/R)( S/T )(L/V/I)(R/K)(R/K)(A/Y) or (W/R)(X)(X)(F/Y/H/T)(Y/W/R)( T )(X)(R/T)(R)(X), where X represents any amino acid. Such a compound may be useful in treating Parkinson's Disease or Parkinsonism. The substrate polypeptide may consist or comprise the sequence RLGWWRFY T LRRARQGNTKQR.
    • 用于鉴定预期用于调节例如抑制LRRK2蛋白激酶活性的化合物的方法,所述方法包括以下步骤:(1)确定测试化合物是否调节,例如抑制LRRK2多肽的蛋白激酶活性 (W / F / R / K)(W / F / R / K)的底物多肽,和(2)选择调节,例如抑制所述LRRK2多肽蛋白激酶活性的化合物。 (R / K)(F / W / H / R)(Y / W / R)(S / T)(L / V / I)(R / K) (W / R)(X)(X)(F / Y / H / T)(Y / W / R)(T)(X)(R / T) 酸。 这种化合物可用于治疗帕金森氏病或帕金森综合征。 底物多肽可以包含或包含序列RLGWWRFYTLRRARQGNTKQR。
