In a study of dominant mutation of LRRK2 (leucine-rich repeat kinase 2) in a Parkinson’s disease (PD) model, TAOK3, serine/threonine kinase 3 (STK3), STK24, and STK25 were identified to be novel LRRK2 substrates that may be involved in LRRK2-induced synaptic dysfunction and neurite fragmentation [64]. Here, STK3 is linked to Parkinson disease.
