Description

Ypt3 Protein CAS NO 129131-32-4 is a recombinant protein belonging to the Rab GTPase family, a key regulator of intracellular vesicular transport. This high-purity protein is essential for fundamental research in cell biology, particularly in studying membrane trafficking, signal transduction, and organelle dynamics. It is a critical reagent for pharmaceutical R&D, biotechnology, and academic laboratories focused on understanding cellular communication and developing targeted therapies.

Application

• Biochemical Research: Used as a standard or substrate in enzymatic assays to study GTPase activity, protein-protein interactions, and regulatory mechanisms in vesicle transport.
• Drug Discovery & Screening: Serves as a target protein in high-throughput screening (HTS) platforms to identify novel inhibitors or modulators of Rab GTPase signaling pathways.
• Antibody Production & Validation: Acts as a high-quality immunogen for generating specific monoclonal or polyclonal antibodies for use in Western blotting, immunohistochemistry, and ELISA.
• Structural Biology Studies: Provides purified protein for X-ray crystallography, NMR spectroscopy, and cryo-EM to elucidate the three-dimensional structure and functional domains.
• Cellular & Molecular Biology: Employed in pull-down assays, co-immunoprecipitation (Co-IP), and fluorescence-based studies to map interaction networks and cellular localization.
• Diagnostic Development: Potential use as a calibrated antigen in the development of diagnostic assays for diseases linked to trafficking defects.
