The MAP1A Knockout Raji Polyclonal Cells product provides a CRISPR/Cas9-mediated gene-disrupted polyclonal population of Raji B lymphocytes, targeting the human MAP1A locus. This mixed-cell population, generated without clonal selection, offers a loss-of-function model for studying microtubule-associated protein 1A (MAP1A) in a B-lymphocyte context. By retaining cellular heterogeneity, the product enables analysis of population-level responses, making it suitable for experiments where clonal artifacts must be avoided and diverse knockout effects can be observed simultaneously.
The Raji host cell line is an EBV-positive Burkitt lymphoma-derived B lymphocyte model widely employed for lymphoma research and immune cell signaling studies. These lymphoblastoid cells exhibit activated B-cell characteristics and are permissive for EBV-driven gene expression programs that influence proliferation and survival. The Raji background provides a clinically relevant platform to investigate B-cell malignancies, particularly the role of microtubule dynamics in lymphoma cell migration, intracellular trafficking, and signal transduction downstream of immune receptors.
MAP1A is a microtubule-associated protein that stabilizes microtubules and regulates neuronal development, axon guidance, and cytoskeletal organization. It functions downstream of Reelin/VLDLR/Dab1 signaling and is modulated by neurotrophins, WNT signaling, and the transcription factor NEUROD1. Mechanistically, MAP1A binds tubulin and interacts with actin filaments, MAP2, Tau, and DPYSL2 to exert its effects on microtubule polymerization and stability. This protein is integral to neuronal migration and polarity, but its expression in B lymphocytes suggests additional roles in cytoskeletal reorganization that may impact immune cell functions.
In the Raji B-lymphocyte model, MAP1A knockout may disrupt microtubule dynamics, potentially altering cell migration, intracellular trafficking, and apoptotic pathways. As microtubules are critical for mitotic spindle formation and vesicular transport, loss of MAP1A function could influence lymphoma cell survival and chemosensitivity, making this model valuable for correlating microtubule-associated protein activity with malignant B-cell behavior. Furthermore, the connection between MAP1A and neurodevelopmental disorders such as intellectual disability, schizophrenia, and autism spectrum disorder positions this cellular system as a cross-disciplinary tool for investigating cytoskeletal contributions to disease mechanisms.
Researchers can apply MAP1A Knockout Raji Polyclonal Cells to a broad range of studies, including B-cell lymphoma microtubule biology, lymphocyte migration assays, and neurodevelopmental disorder modeling using CRISPR functional genomics. Representative assays encompass western blotting for MAP1A and tubulin, RT-qPCR for gene expression profiling, immunofluorescence for cytoskeletal components, cell migration assays, microtubule polymerization assays, apoptosis detection, and flow cytometry. These applications support mechanistic inquiries and cytoskeletal drug screening in a lymphoma context. For technical inquiries and bulk ordering, contact Ascent Research.
