However, known mitochondrial transporters of this amino acid (such as UCP1, UCP2, UCP3, BOU; (Monné et al. 2018; Porcelli et al. 2018)) are either of similar abundance (UCP1, AT3G54110), were not found (UCP2, AT5G58970), or are of lower abundance in GDM (UCP3, AT1G14140; BOU, AT5G46800, Figure S6), suggesting a lower transport capacity for this amino acid into GDM. Here, UCP2 is linked to gestational diabetes.
