Leucine-rich repeat kinase 2 (LRRK2) is a multidomain enzyme encoded by the LRRK2 gene, located on human chromosome 12. It is primarily expressed in various tissues, including brain, kidney, lung, and immune cells. LRRK2 is a member of the ROCO protein family, characterized by the presence of a leucine-rich repeat (LRR), a Ras-like GTPase domain (Roc), a C-terminal (COR) domain of Roc, a kinase domain, and multiple other protein-protein interaction domains. LRRK2 protein plays a crucial role in cellular processes such as apoptosis, autophagy, and vesicle trafficking.
Mutations in the LRRK2 gene have been identified as one of the most common genetic causes of familial and sporadic Parkinson's disease (PD). Significant mutations include G2019S, R1441C/G, and Y1699C, all of which alter kinase activity and lead to neuronal toxicity and death. In particular, the G2019S mutation increases LRRK2 kinase activity, which has been implicated in pathological processes such as alpha-synuclein aggregation, a hallmark of Parkinson's disease.
The Human LRRK2 Knockout Cell Line - HeLa provides a versatile platform for numerous applications in biomedical research. Here are some of the key uses:
Parkinson's Disease Research: LRRK2 mutations are the leading cause of familial Parkinson's disease. This cell line lacking LRRK2 allows researchers to study the cellular and molecular mechanisms behind the disease, which can help identify potential therapeutic targets.
Drug Screening and Development: LRRK2 Knockout HeLa cells can be used to screen for compounds that modulate the activity of pathways affected by LRRK2. This is particularly useful for testing new drugs designed to treat Parkinson's disease and other neurodegenerative diseases.
Gene Function Studies: By comparing knockout cell lines to wild-type cells, scientists can gain insight into the normal biological function of LRRK2, exploring its role in cellular processes such as vesicle trafficking, cytoskeletal dynamics, and autophagy.
Pathway Analysis: These cells can be used to dissect signaling pathways in which LRRK2 participates. This includes the MAPK pathway, intracellular trafficking, and inflammatory responses, helping to gain a broader understanding of cell biology.
Protein Interaction Studies: In the absence of LRRK2, knockout cells can help identify proteins and molecular interactions that are dependent on LRRK2.
Disease Modeling: In addition to Parkinson's disease, LRRK2 has been implicated in several other diseases, such as Crohn's disease and certain types of cancer. This cell line can be used to model these diseases in vitro, helping to better understand how LRRK2 deficiency affects cellular physiology.
Customer Q&As
What is the recommended growth medium? Does it require antibiotic selection?
A: DMEM supplemented with 10% fetal bovine serum.
It is not required to add the selection antibiotics when culturing the KO cells.
How is the knockout cell line validated?
A: The knockout cell product is validated by PCR amplification and Sanger Sequencing to confirm the mutation at the genomic level. Please find the detailed mutation info in the datasheet.
Is the product a single clonal cell or mixed cell pool?
A: Single clonal cell.
Can I confirm gene knockout by RT-qPCR?
A: No. This knockout cell product is generated using the CRISPR/Cas9 system to induce small insertions or deletions (indels) resulting in frameshift mutations. Although these frameshift mutations typically disrupt the coding gene, there is a possibility that the non-functional transcript may still be transcribed. Consequently, this could potentially yield misleading results when analyzed by RT-qPCR.
How can I store the cell product?
A: The cell line should be stored in liquid nitrogen for long-term preservation.
Is it possible to get multiple knockout clones for my GOI?
A: For most cases, we often keep at least 2 clones with different frameshift mutations. Please feel free to contact us to check if there are additional available clones.
