Abstract
Activity-dependent local mRNA translation endows synapses to remodel their structure and function (Bramham and Wells, 2007). This process is tightly controlled by the state of phosphorylation of several components of the translational machinery including initiation factors and ribosomal proteins (Buffington et al., 2014). The present protocol describes a method to prepare striatal synaptoneurosomes, from adult mice, containing both pre- and postsynaptic elements in which the level of synaptic phospho-proteins can be quantified (Biever et al., 2015).
Keywords: Synaptoneurosome (突触神经小体)
