Neuroscience: Greasy proteins of the neuron
Maurine E. Linder1
Abstract
An analysis of neuronal proteins reveals that many are regulated through covalent attachment of the lipid palmitate. This reversible modification seems to affect the form and function of synaptic junctions.
Phosphates, lipids, sugars and even small polypeptides covalently attach to proteins, changing a protein's activity, localization or stability. Such modifications can be either reversible or permanent.
