function:Required for consolidation of synaptic plasticity as well as formation of long-term memory. Regulates endocytosis of AMPA receptors in response to synaptic activity. Required for homeostatic synaptic scaling of AMPA receptors.,similarity:Belongs to the ARC/ARG3.1 family.,subcellular location:Associated with the cell cortex of neuronal soma and dendrites. Enriched in postsynaptic density of dendritic spines. Associated with the sperm tail.,subunit:Interacts with SH3GL1/endophilin-2, SH3GL3/endophilin-3 and DNM2/DYN2.,
