LRRKtide is a peptide substrate for leucine-rich repeat kinase 2 (LRRK2). The sequence of LRRKtide has been derived from the ERM protein family members ezrin (amino acids 561-573), radixin (amino acids 558-570) and moesin (amino acids 539-553), proteins which influence cytoskeletal dynamics by anchoring the cytoskeleton to the plasma membrane. LRRK2 phosphorylates LRRKtide at its Thr558 site. LRRK2 is found in most organs and is involved in several cellular pathways. The LRRK2 gene and alpha-synuclein gene (SNCA) are the key influencing factors of Parkinson€(TM)s disease (PD), with dysfunction of LRRK2 influencing the accumulation of alpha-synuclein.
