BET1L (Bet1 Golgi Vesicular Membrane Trafficking Protein-Like): BET1L is a protein that plays a key role in the vesicular transport system, specifically managing the trafficking between the endoplasmic reticulum and the Golgi apparatus. This process is essential for the proper secretion and processing of proteins, which supports important cellular functions such as cell signaling, metabolism, and structural maintenance. BET1L’s function in this transport pathway is vital for normal cellular operations and maintaining cellular homeostasis.
