Automated description from the Alliance of Genome Resources
A structural constituent of postsynaptic density. Involved in several processes, including cellular response to potassium ion; cytoskeleton-dependent intracellular transport; and neurotransmitter receptor localization to postsynaptic specialization membrane. Localizes to several cellular components, including the glutamatergic synapse; juxtaparanode region of axon; and postsynaptic density. Predicted to colocalize with the ionotropic glutamate receptor complex and voltage-gated potassium channel complex. Orthologous to human DLG2 (discs large MAGUK scaffold protein 2).
