Protein palmitoylation in membrane trafficking
Introduction Protein palmitoylation was first described more than 20 years ago for the myelin proteolipid protein, but the functional significance of this post-translational modification remains obscure. Progress has been hampered by the lack of specific inhibitors for acylation and because of the difficulty of developing an assay to isolate the palmitoylating enzyme(s). Palmitoylation generall...
متن کاملCellular palmitoylation and trafficking of lipidated peptides.
Many important signaling proteins require the posttranslational addition of fatty acid chains for their proper subcellular localization and function. One such modification is the addition of palmitoyl moieties by enzymes known as palmitoyl acyltransferases (PATs). Substrates for PATs include C-terminally farnesylated proteins, such as H- and N-Ras, as well as N-terminally myristoylated proteins...
متن کاملPalmitoylation regulates the intracellular trafficking and stability of c-Met
c-Met is a receptor tyrosine kinase whose activity can promote both mitogenic and motogenic phenotypes involved in tissue development and cancer progression. Herein, we report the first evidence that c-Met is palmitoylated and that palmitoylation facilitates its trafficking and stability. Inhibition of palmitoylation reduced the expression of c-Met in multiple cancer cell lines post-transcripti...
متن کاملPalmitoylation and the trafficking of peripheral membrane proteins.
Palmitoylation, the attachment of palmitate and other fatty acids on to cysteine residues, is a common post-translational modification of both integral and peripheral membrane proteins. Dynamic palmitoylation controls the intracellular distribution of peripheral membrane proteins by regulating membrane-cytosol exchange and/or by modifying the flux of the proteins through vesicular transport sys...
متن کاملRegulation of SNAP-25 trafficking and function by palmitoylation.
The SNARE (soluble N-ethylmaleimide-sensitive fusion protein-attachment protein receptor) protein SNAP-25 (25 kDa synaptosome-associated protein) is essential for regulated exocytosis in neuronal and neuroendocrine cells. Whereas the majority of SNARE proteins contain transmembrane domains, SNAP-25 is instead anchored to membranes by the palmitoylation of a central cysteine-rich region. In this...
