Description
Appears to be involved in vesicular protein trafficking, mainly in the early secretory pathway. In COPI vesicle-mediated retrograde transport involved in the coatomer recruitment to membranes of the early secretory pathway. Increases coatomer-dependent activity of ARFGAP2. Thought to play a crucial role in the specific retention of p24 complexes in cis-Golgi membranes; specifically contributes to the coupled localization of TMED2 and TMED10 in the cis-Golgi network. May be involved in organization of intracellular membranes, such as of the ER-Golgi intermediate compartment and the Golgi apparatus. Involved in ER localization of PTPN2 isoform PTPB.

Descripción
TMED9 is a critical member of the p24 protein family that regulates protein trafficking between the endoplasmic reticulum (ER), ER-Golgi intermediate compartment (ERGIC), and the Golgi apparatus. It functions as a cargo receptor, facilitating the export of correctly folded proteins through COPII-coated vesicles and supporting retrograde retrieval via COPI transport machinery. TMED9 also regulates protein quality control, ensuring proper sorting, maturation, and recycling of secretory and membrane-bound proteins. It plays additional roles in signaling pathways, including Wnt and growth factor signaling, by modulating receptor trafficking and localization at the plasma membrane. TMED9 is widely expressed, particularly in secretory cells, immune tissues, and proliferative compartments. Dysregulation of TMED9 has been associated with cancers and metabolic diseases, where altered trafficking dynamics impair protein secretion and receptor signaling. Knockdown studies reveal defects in vesicle formation, impaired Golgi organization, and disrupted cellular homeostasis, emphasizing its essential role in coordinating vesicular transport, protein quality control, and signaling regulation.
