MuSK (h3): 293T Lysate: sc-369501

MuSK (h3): 293T Lysate, derived from the HEK 293T cell line, is a crucial tool for investigating the Muscle-Specific Kinase (MuSK), a receptor tyrosine kinase essential for neuromuscular junction (NMJ) formation and maintenance. The HEK 293T cell line, a human embryonic kidney cell variant, has been modified to express the SV40 large T antigen, enabling high-efficiency protein expression and replication. This makes the lysate particularly valuable for studying the molecular mechanisms underlying MuSK's function. Researchers use MuSK (h3): 293T Lysate to explore how MuSK is activated by agrin, a nerve-derived proteoglycan, leading to the clustering of acetylcholine receptors (AChRs) on the muscle cell membrane. This activation is crucial for NMJ development. Techniques such as immunoprecipitation, Western blotting, and kinase activity assays are employed to investigate MuSK's role in signal transduction pathways. These studies often focus on understanding the interactions between MuSK and downstream signaling molecules like Dok-7 and rapsyn, which are critical for AChR clustering and NMJ stabilization. By utilizing this lysate, scientists gain insights into the fundamental processes of synaptic formation and maintenance, providing a deeper understanding of the molecular basis of neuromuscular connectivity.
