Modulating pseudokinase conformation from the ATP-binding site

SUMMARY Pseudokinase domains (PsKDs) mediate key signaling processes involved in human disease. Despite transformative success in targeting catalytically active protein kinases, drug development for pseudokinases has lagged behind. Although they lack catalytic activity, pseudokinases are conformationally dynamic and ar...

The structural basis for LRRK2’s activation and autoinhibition

Mutations in Leucine-Rich Repeat Kinase 2 (LRRK2) are the second most common cause of autosomal-dominant Parkinson’s disease (PD), and increased LRRK2 kinase activity is also observed in idiopathic PD, making LRRK2 a major actionable therapeutic target. LRRK2 is a 286-kDa multidomain enzyme containing a Ras-like GTPase...

The structural basis for LRRK2's activation and autoinhibition.

A unified framework for understanding LRRK2 regulation with broad therapeutic implications is provided, showing that the ROC GTPase governs switching between autoinhibited and active states: GTP binding promotes activation, whereas GDP binding enforces autoinhibition.
