What is the Importance of PSD-95 in Postsynaptic Densities?
PSD-95 is a major scaffolding protein within PSDs and plays a critical role in organizing and stabilizing synaptic components. It interacts with various proteins, including receptors and signaling molecules, to maintain the structural integrity of the PSD. PSD-95 is also involved in the trafficking and anchoring of NMDA receptors, which are vital for synaptic plasticity.
