2012 and references therein). Kcna4 which encodes potassium voltage-gated channel subfamily A member four, is recruited to the synapse by PSD95, where it is phosphorylated (Wong and Schlichter, 2004). Kif1a encodes a kinsin family three member which is also known as axonal transporter of synaptic vesicles. Mutations in the Drosophila homolog unc-104, have revealed the importance of the protein product in glutamate spontaneous release and in post-synaptic density organization (Zhang et al., 2017).
