Proteomics datasets of developing rat brain: Synaptic proteome and SUMO2/3-ylome.

ABSTRACT: During brain development, synapses undergo structural rearrangements and functional changes mediated by many molecular processes including post-translational modifications by the Small Ubiquitin-like MOdifier (SUMO). To get an overview of the endogenous SUMO-modified proteins in the developing rat brain synapses, our first aim was to characterize the synaptic proteome from rat at 14 postnatal days (PND14), a period that combines intense synaptogenesis, neurotransmission and high levels of SUMO2/3-ylation. In this purpose, we isolated the synaptosomal fraction by differential centrifugation on sucrose percoll gradient and characterized the synaptosomal proteome by nanoLC-MS/MS. Our second aim was to provide a comprehensive list of the SUMO2/3-modified protein in this compartment. We thus pe
