Involved in potassium ion transmembrane transport; regulation of presynaptic cytosolic calcium ion concentration; and regulation of synaptic vesicle exocytosis. Is integral component of plasma membrane. Is active in parallel fiber to Purkinje cell synapse. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and integumental system.

n this report, we present two independent screening campaigns in which we wanted to identify small molecules that bind to either the intracellular cytoplasmic amino terminal Per-Arnt-Sim (PAS) domain from the human EAG-related gene (ERG) channel or the amino or carboxy terminal globular domains from the mouse EAG1 channel, affecting their interaction.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
