Supplementary information

STARD4 or StAR-related lipid transfer protein 4 is a cytosolic protein involved in cholesterol transport. It is approximately 22 kDa in size. This protein facilitates the shuttling of cholesterol between cellular membranes and the cytoplasm. Expression of STARD4 is found in various tissues but it is notably present in the liver and macrophages. Its role in these tissues supports overall cholesterol homeostasis by regulating intracellular cholesterol distribution.
Biological function summary

This protein participates in intracellular lipid trafficking as part of larger biosynthetic and regulatory processes. It does not function independently but rather interacts with several lipid-binding proteins to control cholesterol availability within the cell. These interactions are essential for maintaining membrane integrity and the synthesis of steroid hormones. The activity of STARD4 directly influences the regulation of lipid metabolism and energy homeostasis.

Pathways

STARD4 contributes to lipid metabolism and homeostasis pathways. It plays a role in the cholesterol transport pathway specifically in concert with proteins like STARD1 and STARD5 which also bind and transfer cholesterol. Its function ensures proper cholesterol distribution required for cellular signaling and membrane structure. The activity of STARD4 intersects with other proteins involved in these pathways such as apolipoproteins and other lipid-binding proteins to maintain lipid balance within tissues particularly in organs like the liver.

STARD4 is associated with conditions linked to cholesterol imbalance such as atherosclerosis and non-alcoholic fatty liver disease (NAFLD). Altered expression or function of STARD4 can disrupt normal cholesterol homeostasis contributing to the development of these disorders. Research indicates that its interactions with proteins such as low-density lipoprotein (LDL) receptors and apolipoprotein E (ApoE) are critical in understanding disease mechanisms. Modification in the function or expression of STARD4 can signify altered lipid transport and contribute to pathogenesis in related disorders.
