Acetylation of proteins is a post-translational modification mediated by specific acetyltransferases, using the donor acetyl CoA. SLC33A1/AT1 is a putative 11 TM transporter present on the endoplasmic reticulum, expressed in all tissues, but particularly abundant in the pancreas [2], which imports cytosolic acetyl CoA into these intracellular organelles.
