Acyl-protein thioesterase 2 catalyzes the deacylation of peripheral membrane-associated GAP-43. In this work, we investigated the deacylation of growth-associated protein-43 (GAP-43), a dually acylated protein at cysteine residues 3 and 4. Thus, the results demonstrate that APT-2 is the protein thioesterase involved in the acylation/deacylation cycle operating in GAP-43 subcellular distribution.we demonstrated that the reduction in the protein level was abrogated when cells were also treated with proteasome inhibitors (chloroquine, MG132 and lactacystin) which strongly suggest that GAP-43 deacylation is an early and necessary step for its later ubiquitination and degradation by the proteasome. In addition, it also suggests that acyl-protein thioesterase levels not only regulate palmitate turnover but also global protein turnover of GAP-43. |
