Protein Information (annotations from UniProt)

Database IDHIV0002715
UniProt IDQ6PCB7
Primary gene name(s)SLC27A1
Synonym gene name(s)ACSVL5, FATP1
Protein nameLong-chain fatty acid transport protein 1
Protein functionInvolved in translocation of long-chain fatty acids, LFCA across the plasma membrane. The LFCA import appears to be hormone-regulated in a tissue-specific manner. In adipocytes, but not myocytes, insulin induces a rapid translocation of FATP1 from intracellular compartments to the plasma membrane, paralleled by increased LFCA uptake. May act directly as a bona fide transporter, or alternatively, in a cytoplasmic or membrane-associated multimeric protein complex to trap and draw fatty acids towards accumulation. Plays a pivotal role in regulating available LFCA substrates from exogenous sources in tissues undergoing high levels of beta-oxidation or triglyceride synthesis. May be involved in regulation of cholesterol metabolism. Has acyl-CoA ligase activity for long-chain and very-long-chain fatty acids, By similarity. {ECO:0000250, ECO:0000269|PubMed:12235169}.
Subcellular locationCell membrane {ECO:0000269|PubMed:12235169};

Single-pass membrane protein {ECO:0000269|PubMed:12235169}. Cytoplasm {ECO:0000250}. Note=Plasma membrane and intracellular membranes, at least in adipocytes. Predominantly cytoplasmic in myocytes, By similarity. {ECO:0000250}.
