  • 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 (By similarity). Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the stress fiber dynamics and cell migration.
  • Sequence similarities

    Belongs to the ARC/ARG3.1 family.
  • Cellular localization

    Cytoplasm > cytoskeleton. Endosome. Cytoplasmic vesicle > secretory vesicle > acrosome. Cell junction > synapse > postsynaptic cell membrane > postsynaptic density. Cell projection > dendrite. Cell projection > dendritic spine. Cell junction > synapse. Associated with the cell cortex of neuronal soma and dendrites. Enriched in postsynaptic density of dendritic spines. Associated with the sperm tail (By similarity). Enriched on the plasma membrane.
