Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
It is reported to have molecular function: voltage-gated potassium channel activity; potassium channel activity.
It is reported to be involved in the biological process: potassium ion transport.
8 alleles are reported.
No phenotypic data is available.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Cyclic nucleotide-binding domain; Cyclic nucleotide-binding-like; Ion transport; PAC motif; PAS; PAS fold-3; PAS-associated, C-terminal; Potassium channel, voltage-dependent, EAG/ELK/ERG; Potassium channel, voltage-dependent, ELK; RmlC-like jelly roll fold.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of low expression to a trough of extremely low expression.
Peak expression observed within 12-24 hour embryonic stages, at stages throughout the larval period, at stages throughout the pupal period, in adult male stages.
