Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Protocols

Specificity / Sensitivity

The LRRK2 Antibody is recommended for transfected total LRRK2 only. The LRRK2 antibody detects a background band in extracts of wild-type and LRRK2 knock-out mouse brain at ~290kD.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide surrounding Gly2090 of human LRRK2. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from HEK-293 cells, transfected with GFP alone (lane 1) or GFP-LRRK2 (lane 2), using LRRK2 Antibody.

Background

Parkinson’s disease (PD), the second most common neurodegenerative disease after Alzheimer’s, is a progressive movement disorder characterized by rigidity, tremors, and postural instability. The pathological hallmark of PD is progressive loss of dopaminergic neurons in the substantia nigra of the ventral midbrain and the presence of intracellular Lewy bodies (protein aggregates of α-synuclein, ubiquitin, and other components) in surviving neurons of the brain stem (1). Various genes and loci (α-synuclein/PARK1 and 4, parkin/PARK2, UCH-L1/PARK5, PINK1/PARK6, DJ-1/PARK7, LRRK2/PARK8, synphilin-1, and NR4A2) are genetically linked to PD (2).Leucine-rich repeat kinase 2 (LRRK2) contains amino-terminal leucine-rich repeats (LRR), a Ras-like small GTP binding protein-like (ROC) domain, an MLK protein kinase domain, and a carboxy-terminal WD40 repeat domain. At least 20 LRRK2 mutations have been linked to PD-the G2019S mutation being the most prevalent (3). The G2019S mutation causes increased LRRK2 kinase activity, which induces a progressive reduction in neurite length, leading to progressive neurite loss and decreased neuronal survival (4). The MLK inhibitor CEP-1347 is being tested in PD clinical trials, indicating the potential value of LRRK2 as a therapeutic target for treatment of PD (5).
