Bressloff, along with mathematical biologist Berton Earnshaw, conceived of the dendritic spine — the mushroom shape at the downstream end of the neuron — as a two - compartment box: On the far downstream end, essentially in the synapse, scaffolding proteins suspend AMPA receptors so they can bind glutamate signals coming from the upstream neuron.

Beyond that, he continues, «at the timescale of hours, scaffolding proteins can be moved in and out, so again things would lose the memory, so you need something else, like changing the actual structure of the dendritic spine.»

Homer 1, an actin binding protein that is induced by BDNF [72], belongs to a family of scaffolding proteins that localize at the postsynaptic density (PSD)[73, 74] and is believed to play a critical role in signal transduction, synaptogenesis and receptor trafficking at synapses [75].

It will be important, Panne says, to dissect in detail how scaffold proteins, such as the CBP and p300 co-activators, contribute to the rich gene regulatory language, how such chromatin modifiers are targeted to the genome, how their activity is regulated, and how chromatin modifications contribute to the signaling reaction.
