Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: A-type (transient outward) potassium channel activity.
It is reported to be involved in the biological process: potassium ion transport.
10 alleles are reported.
No phenotypic data is available.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: BTB/POZ fold; BTB/POZ-like; Ion transport; Potassium channel, voltage dependent, Kv; Potassium channel, voltage dependent, Kv, tetramerisation; Potassium channel, voltage dependent, Kv4; Shal-type voltage-gated potassium channels; Voltage-dependent potassium channel.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of very low expression.
Peak expression observed within 18-24 hour embryonic stages, during early larval stages.
