Abstract
PURPOSE OF REVIEW: Fatty acid transport proteins are a family of proteins involved in fatty acid uptake and activation. This review summarizes recent progress in elucidating the function of fatty acid transport proteins. RECENT FINDINGS: Recent experiments clearly establish FATP1 as a regulated fatty acid transporter in both adipose tissue and muscle with important roles in energy homeostasis, thermogenesis and insulin resistance. Knockout of FATP5 in mice show it to be a bifunctional protein required for both hepatic fatty acid uptake and bile acid reconjugation. The most striking phenotype of FATP4 deletion is a defect in skin homeostasis, which may be due to its very long chain acyl-coenzyme A synthetase activity. Fatty acid transport proteins are increasingly being recognized as multifunctional proteins that can mediate the uptake of fatty acids as well as catalyze the formation of coenzyme A derivatives using long-chain and very-long chain fatty acids, bile acids and bile acid precursors as substrates. SUMMARY: Modulation of fatty acid transport protein function can result in altered energy homeostasis and insulin sensitivity, defective skin homeostasis, and altered bile acid metabolism. Both fatty acid uptake and enzymatic activity of fatty acid transport proteins likely contribute to these phenotypes. Future studies are needed to better understand the molecular mechanism of fatty acid transport protein function and the physiological role of FATP2, FATP3, and FATP6.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
