The MRS2 Knockout Raji Polyclonal Cells represent a CRISPR/Cas9-edited polyclonal knockout cell population derived from human Raji B lymphocytes, designed to disrupt MRS2 gene function. This heterogeneous loss-of-function model enables robust investigation of mitochondrial magnesium transport without clonal selection bias, providing a valuable tool for functional genomics and drug screening studies.
Raji cells are a human Burkitt’s lymphoma B-cell line that retains key features of mature B lymphocytes, including antibody production and antigen presentation. Widely used in immunology and cancer research, their rapid growth and genetic tractability make them an excellent host for CRISPR-mediated gene disruption, especially for studying links between mitochondrial metabolism and B-cell malignancies.
MRS2 encodes a mitochondrial inner membrane magnesium channel that mediates matrix Mg2+ uptake, regulated by cytoplasmic magnesium levels and mitochondrial biogenesis signals. MRS2 interacts with the mitochondrial protein import machinery and Mg2+-binding proteins, and its activity is critical for ATP synthesis, oxidative phosphorylation, and apoptosis suppression. It functionally cooperates with VDAC and MCU to maintain mitochondrial cation homeostasis and energy metabolism.
In Raji cells, MRS2 knockout impairs mitochondrial Mg2+ accumulation, leading to reduced respiratory capacity, heightened apoptosis sensitivity, and metabolic reprogramming??hallmarks of magnesium deficiency and mitochondrial dysfunction. This model is particularly pertinent to cancer metabolism research, as lymphomas often rely on robust mitochondrial function for growth, and targeting magnesium homeostasis may expose therapeutic vulnerabilities.
These polyclonal knockout cells are ideal for studying magnesium homeostasis, mitochondrial transporter function, and cancer metabolism. Researchers can use Western blotting and RT-qPCR to verify MRS2 disruption, immunofluorescence for mitochondrial morphology, and cation-sensitive dyes to measure Mg2+ and Ca2+ fluxes. Functional readouts include Annexin V assays for apoptosis, ATP-level measurements, and metabolic flux analysis. For additional information, please contact Ascent Research.
