Summary: Enables inward rectifier potassium channel activity. Acts upstream of or within potassium ion transmembrane transport. Predicted to be located in membrane. Predicted to be part of monoatomic ion channel complex. Predicted to be active in plasma membrane. Is expressed in several structures, including heart; myotome; olfactory system; pectoral fin; and pharyngeal arch. Human ortholog(s) of this gene implicated in Andersen-Tawil syndrome; familial atrial fibrillation; familial periodic paralysis; and short QT syndrome. Orthologous to human KCNJ2 (potassium inwardly rectifying channel subfamily J member 2). [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.
