Herein, we report cloning and subcellular localization of two alanine aminotransferase (ALT) isozymes, cALT and mALT, from liver of gilthead sea bream (Sparus aurata). CHO cells transfected with constructs expressing cALT or mALT as C- or N-terminal fusion with the enhanced green fluorescent protein (EGFP) showed that cALT is cytosolic, whereas mALT localized to mitochondria. Fusion of EGFP to mALT N-terminus or removal of amino acids 1-83 of mALT avoided import into mitochondria, supporting… CONTINUE READING
