Summary: Predicted to enable inward rectifier potassium channel activity. Predicted to be involved in potassium ion import across plasma membrane and regulation of monoatomic ion transmembrane transport. Predicted to be part of monoatomic ion channel complex. Predicted to be active in plasma membrane. Is expressed in brain; male reproductive gland or organ; metanephros; and respiratory system.

Kcnj13 mutants exhibit a shorter trachea as well as defective smooth muscle cell alignment and polarity. Kcnj13 is essential to maintain ion homeostasis in tracheal smooth cells, which is required for actin polymerization and is mediated, at least in part, through activation of the actin regulator, AKT.

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.
