Automated description from the Alliance of Genome Resources (Release 5.3.0)
Enables transmembrane transporter binding activity. Involved in several processes, including cellular response to magnesium ion; negative regulation of delayed rectifier potassium channel activity; and neuronal action potential. Acts upstream of or within axon guidance; protein localization to axon; and synapse organization. Located in several cellular components, including intercalated disc; main axon; and synapse. Is expressed in central nervous system and heart. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder 37; bipolar disorder; and schizophrenia. Orthologous to human ANK3 (ankyrin 3).
