Slc1a5, also known as Asct2, was of borderline significance by interactome analysis ( Figures 4A and 4B ) but has been shown to be palmitoylated 12 and is the only glutamine transporter known to localize to mitochondria. 37 Because APT1 and APT2 are each palmitoylated near their N terminus, 36 we anticipated interactions with acyltransferases.

Hepatic palmitoyl-proteomes and acyl-protein thioesterase protein proximity networks link lipid modification and mitochondria.
