STARD5 (StAR-Related Lipid Transfer Domain Containing 5): STARD5 is a protein that reflects the activity of the START domain family, involved in the transport and distribution of lipids within cells. It plays a key role in regulating lipid metabolism and maintaining lipid homeostasis, particularly in the liver and gastrointestinal tract. While its specific functions are still being studied, STARD5’s role in lipid transport suggests potential implications for metabolic disorders and diseases related to lipid dysregulation.
