Transmembrane Emp24 Domain-Containing Protein 10 (TMED10) Antibody

Background

TMED10, also known as p24δ1, is a critical component of the p24 family involved in regulating vesicular trafficking between the endoplasmic reticulum (ER), ER-Golgi intermediate compartment (ERGIC), and Golgi apparatus. It functions as a cargo receptor, facilitating the efficient transport of membrane and secretory proteins by interacting with COPII and COPI coat complexes during vesicle budding and retrieval. TMED10 plays an essential role in maintaining Golgi organization, protein sorting, and ER homeostasis, ensuring the proper maturation and localization of secretory proteins. It is ubiquitously expressed and is particularly abundant in rapidly dividing and secretory tissues. TMED10 has also been implicated in cellular signaling, including Wnt signaling and autophagy, where it modulates receptor trafficking and degradation pathways. Dysregulation of TMED10 is associated with neurodegenerative diseases, immune dysfunction, and cancers, where defective trafficking leads to protein mislocalization and stress. Knockdown studies reveal disrupted Golgi morphology, impaired protein secretion, and increased ER stress, highlighting its essential role in vesicular transport, protein homeostasis, and signaling regulation.
