SPA-1 (m): 293T Lysate: sc-123727

SPA-1 (m): 293T Lysate is derived from the human embryonic kidney 293T cell line, genetically engineered to express the mouse signal-induced proliferation-associated 1 (SPA-1) protein. SPA-1 is a critical regulator of the Rap1 signaling pathway, which is involved in cell adhesion, cell junction formation, and cell migration. The 293T cell line is chosen for its high transfection efficiency and robust protein expression, making it an ideal system for producing SPA-1 lysates. In research, SPA-1 (m): 293T Lysate is utilized to study the molecular mechanisms by which SPA-1 regulates Rap1 activity. SPA-1 functions as a GTPase-activating protein (GAP) for Rap1, accelerating the hydrolysis of GTP to GDP, thus inactivating Rap1 and modulating its downstream signaling pathways. Researchers employ this lysate in various biochemical assays, including Western blotting, immunoprecipitation, and GTPase assays, to analyze SPA-1 expression, interaction with Rap1, and its regulatory effects on Rap1 activity. Additionally, SPA-1 (m): 293T Lysate is used in cell-based assays to investigate the role of SPA-1 in cell adhesion, migration, and junction formation. This lysate helps to explain the crosstalk between SPA-1/Rap1 signaling and other pathways, such as integrin and cadherin signaling, which are crucial for maintaining cellular architecture and tissue integrity. Through these studies, researchers gain insights into the complex regulatory networks involving SPA-1, advancing our understanding of cellular signaling and its impact on cell behavior.
