LRRKtide (also called moesin) is a peptide substrate for leucine-rich repeat kinase 2 (LRRK2). The sequence of LRRKtide has been derived from the ERM proteins: Ezrin (amino acids 561-573), radixin (amino acids 558-570) and moesin (amino acids 539-553). These proteins influence cytoskeletal dynamics by anchoring the cytoskeleton to the plasma membrane. LRRK2 phosphorylates LRRKtide at its Thr558 site. This peptide contains the phosphorylated threonine residue.

LRRK2 is a large, ubiquitous protein of unknown function. LRRK2 has GTPase and kinase activity, and is located in multiple areas of the cell, associated with intracellular membranes and vesicular structures; suggesting LRRK2 may be involved in several cellular pathways. LRRK2 is also found in most organs and mutations in LRRK2 have been identified in Parkinson’s disease
