The function of ADTRP (androgen dependent TFPI regulating protein, Ensembl gene identifier ENSG00000111863) is as follows. Hydrolyzes bioactive fatty-acid esters of hydroxy-fatty acids (FAHFAs), but not other major classes of lipids (PubMed:27018888). Show a preference for FAHFAs with branching distal from the carboxylate head group of the lipids (PubMed:27018888). Regulates the expression and the cell-associated anticoagulant activity of the inhibitor TFPI in endothelial cells (in vitro) (PubMed:21868574). .
