Summary: Enables identical protein binding activity and signaling receptor binding activity. Involved in several processes, including membrane hyperpolarization; potassium ion import across plasma membrane; and response to corticosteroid. Located in several cellular components, including astrocyte projection; basolateral plasma membrane; and microvillus. Used to study diabetic retinopathy. Biomarker of amyotrophic lateral sclerosis; brain disease (multiple); eye disease (multiple); and sensorineural hearing loss. Human ortholog(s) of this gene implicated in EAST syndrome and autosomal recessive nonsyndromic deafness 4. Orthologous to human KCNJ10 (potassium inwardly rectifying channel subfamily J member 10).

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.
