TMED1, also known as p24γ1, is a member of the transmembrane emp24 domain-containing (TMED) protein family. These proteins are crucial for intracellular protein transport, especially in the bidirectional transport between the endoplasmic reticulum (ER) and the Golgi apparatus, which is essential for normal embryonic development and various cellular functions [1,3,4].

In colorectal cancer (CRC), integrative multi-omics analysis shows that highly expressed TMED1 is related to poor prognosis. Knocking down TMED1 reduces cell growth and increases apoptosis. Its expression is positively correlated with other TMED family members in CRC and is associated with immune cell infiltration and drug resistance [2]. In C. elegans, tmed-1 (homologous to human TMED1) can compensate for tmed-3 in some functions, and mutants of these genes show defects in embryonic viability, movement, and vulval morphology, suggesting a role in tissue reorganization during development [4].

In conclusion, TMED1 plays a significant role in protein vesicular trafficking and is involved in important biological processes such as development and disease-related events like in colorectal cancer. Studies in genetic models like C. elegans and through knockdown experiments in CRC cells have provided insights into its functions, highlighting its potential as a prognostic biomarker and therapeutic target in certain diseases.
