LRRK2，（富白氨酸重複激酶2（英語：Leucine-rich repeat kinase 2），又叫震顫素（英語：dardarin）），在人類是由PARK8基因編碼的一個酶。LRRK2是富白氨酸重複激酶家族的一個成員。這個基因的變異與柏金遜症和克隆氏症危險性增高相關。

功能

LRRK2基因編碼的蛋白擁有一個犰狳重複區域、一個錨蛋白重複區域、一個富白氨酸重複結構域、一個激酶結構域、一個RAS結構域、一個鳥苷三磷酸酶結構域和一個WD40重複結構域。此蛋白大部分存在於細胞質中，但也與線粒體外膜結合。

LRRK2與Parkin連接酶C端RING(Really Interesting New Gene)指結構域有相互作用，而Parkin與LRRK2的COR結構域有相互作用。突變型LRRK2的表達誘導成神經細胞瘤和小鼠大腦皮質神經元的細胞凋亡。
