Fatty acid transport protein 4 (IPR030304)

Short name: FATP4

Overlapping homologous superfamilies


Family relationships



Fatty acid transport protein 4 (FATP4; also known as very long-chain acyl-CoA synthetase 4, ACSVL4) belongs to the FATP family, whose members facilitate long- and very long-chain fatty acid uptake [PMID: 23271751, PMID: 15469937]. It exhibits acyl-CoA synthetase activity and has been proposed to facilitate uptake of fatty acids indirectly by mediating their esterification to CoA [PMID: 11404000]. Mutations in FATP4 cause ichthyosis prematurity syndrome (IPS), characterised by premature birth, respiratory distress, and edematous skin with severe ichthyotic scaling [PMID: 25184958].
