CAMSAP1 (Calmodulin-regulated Spectrin-associated Protein 1) is a member of the CAMSAP/Patronin family, which plays a critical role in organizing microtubule networks by stabilizing their minus ends and anchoring them to non-centrosomal sites. Unlike centrosomal microtubule-organizing centers, CAMSAP1 regulates microtubule dynamics in polarized cells, influencing cell shape, motility, and intracellular transport. Antibodies targeting CAMSAP1 are essential tools for studying its localization, expression, and interaction with cytoskeletal components.
CAMSAP1 antibodies are widely used in techniques like immunofluorescence, Western blotting, and immunoprecipitation to explore its role in cellular processes such as mitotic spindle orientation, neuronal development, and epithelial cell polarization. They help identify CAMSAP1’s involvement in diseases linked to microtubule dysfunction, including neurodegenerative disorders and cancer.
Most CAMSAP1 antibodies are raised against specific epitopes, often within its conserved N-terminal domain, and are validated for species reactivity (e.g., human, mouse, rat). Researchers prioritize antibodies with high specificity, often verified via knockout cell lines or siRNA-mediated depletion. Commercial CAMSAP1 antibodies are typically available as monoclonal or polyclonal formats, with rabbit and mouse being common host species.
Understanding CAMSAP1’s regulatory mechanisms through these antibodies has advanced insights into cytoskeletal biology, making them indispensable for studies on cell architecture, division, and disease mechanisms.
