Descriptions

Leucine-rich repeat serine/threonine-protein kinase 1 (LRRK1) is a protein involved in the negative regulation of bone mass, acting through the maturation of osteoclasts. In contrast to the mechanism of autoinhibition that occurs in LRRK2, the autoinhibition of LRRK1 is mediated by a steric mechanism involving the ANK domain, which blocks access to the active site of the kinase domain in a dimer-dependent manner. In contrast, the interaction of the N-terminal LRR domain with the N-lobe of the kinase domain contributes to the alleviation of autoinhibition by changing its position relative to the WD40 domain, exposing the exposure of the active site of the kinase domain. The autoinhibited dimer of LRRK1 could be stabilized by a loop (1791-1907) in the WD40 domain. In addition, the kinase activity of LRRK1 is also regulated by the interaction of its COR-B loop with the kinase domain. Phosphorylation of three residues (S1064, T1074, and S1075) in the autoinhibitory COR-B loop significantly increases the kinase activity of LRRK1. Phosphorylation by Rab7a, resulting in the F1065A mutation, also alleviates the autoinhibited state of LRRK1.
