Summary: Predicted to enable potassium channel activity; potassium channel inhibitor activity; and transmembrane transporter binding activity. Predicted to contribute to delayed rectifier potassium channel activity and voltage-gated potassium channel activity involved in ventricular cardiac muscle cell action potential repolarization. Predicted to be involved in several processes, including negative regulation of delayed rectifier potassium channel activity; potassium ion export across plasma membrane; and regulation of heart rate by cardiac conduction. Predicted to be located in apical plasma membrane. Predicted to be part of voltage-gated potassium channel complex. Is expressed in heart and heart ventricle. Orthologous to human KCNE4 (potassium voltage-gated channel subfamily E regulatory subunit 4). [provided by Alliance of Genome Resources, Nov 2024]

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.
