Target type: molecularfunction
Enables the transfer of a long-chain fatty acid from one side of a membrane to the other. A long-chain fatty acid has an aliphatic tail containing 13 to 22 carbons. [ISBN:0198506732]
Long-chain fatty acid transmembrane transporter activity involves the movement of long-chain fatty acids (LCFAs) across biological membranes. This process is crucial for the uptake, distribution, and utilization of LCFAs, which serve as essential energy sources, building blocks for lipids, and signaling molecules. LCFAs are amphipathic molecules with a hydrophilic head group and a hydrophobic tail, making them difficult to traverse the hydrophobic interior of cell membranes. Transmembrane transporters facilitate this movement by providing a pathway for LCFAs to cross the membrane without disrupting its structural integrity. These transporters typically exhibit high specificity for LCFAs and may display selectivity for specific chain lengths or saturation levels. The mechanism of transport can vary depending on the transporter, but it often involves a conformational change in the protein that allows the LCFA to bind and be transported across the membrane. Long-chain fatty acid transmembrane transporter activity plays a crucial role in various physiological processes, including lipid metabolism, energy production, cell signaling, and membrane biogenesis. Dysregulation of this activity can contribute to metabolic disorders, such as obesity and diabetes.'
