Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: inward rectifier potassium channel activity.
There is experimental evidence that it is involved in the biological process: potassium ion transport; regulation of membrane potential.
5 alleles are reported.
No phenotypic data is available.
It has 3 annotated transcripts and 3 annotated polypeptides.
Protein features are: Immunoglobulin E-set; Potassium channel, inwardly rectifying, Kir; Potassium channel, inwardly rectifying, Kir, conserved region 2; Potassium channel, inwardly rectifying, Kir, cytoplasmic; Potassium channel, inwardly rectifying, Kir-like.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of extremely low expression.
Peak expression observed within 18-24 hour embryonic stages, during early larval stages.
