The RAB4B (N-term) antibody is a selective immunological tool designed to detect the N-terminal region of the RAB4B protein, a member of the Rab GTPase family. RAB4B belongs to the Ras-related small GTP-binding protein superfamily and plays a critical role in regulating intracellular vesicular trafficking, particularly in early endosomal sorting and recycling of membrane receptors, such as EGFR and GLUT4. It is involved in coordinating the shuttling of cargo between endosomes, plasma membrane, and the Golgi apparatus, impacting cellular processes like signal transduction, nutrient uptake, and receptor degradation.
This antibody is commonly used in applications such as Western blotting, immunofluorescence, and immunoprecipitation to study RAB4B expression, localization, and function in various cell types or tissues. Its specificity for the N-terminal domain helps distinguish RAB4B from closely related isoforms (e.g., RAB4A) or other Rab proteins, minimizing cross-reactivity. Researchers employ it to investigate dysregulation of endocytic pathways linked to diseases, including cancer, diabetes, and neurological disorders, where aberrant vesicular trafficking is implicated.
Produced in hosts like rabbit or mouse, the antibody’s performance is often validated using knockout controls or siRNA-mediated silencing to confirm target specificity. Commercial versions may include carrier proteins or stabilizers for enhanced longevity. Studies utilizing this antibody have contributed to elucidating RAB4B’s role in autophagy, lysosomal sorting, and its interaction with effector proteins like Rabenosyn-5 or VPS35. advancing understanding of cellular trafficking mechanisms.
