    Summary
    Enables several functions, including ATP binding activity; ATP-activated inward rectifier potassium channel activity; and potassium ion binding activity. Involved in several processes, including cellular response to magnesium ion; potassium ion import across plasma membrane; and response to potassium ion. Predicted to be part of monoatomic ion channel complex. Predicted to be active in plasma membrane. Biomarker of nephrotic syndrome. Human ortholog(s) of this gene implicated in Bartter disease type 2. Orthologous to human KCNJ1 (potassium inwardly rectifying channel subfamily J member 1).

    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.
