Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: voltage-gated anion channel activity.
There is experimental evidence that it is involved in the biological process: phototransduction; sperm mitochondrion organization; sperm individualization; ion transport; mitochondrion organization.
36 alleles are reported.
The phenotypes of these alleles are annotated with: photoreceptor; Nebenkern; embryonic/larval neuromuscular junction; testis; cystic bulge; waste bag; mitochondrion; seminal vesicle; indirect flight muscle.
It has 4 annotated transcripts and 4 annotated polypeptides.
Protein features are: Porin, eukaryotic type.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of high expression.
Peak expression observed at stages throughout embryogenesis, at stages throughout the larval period, at stages throughout the pupal period, in stages of adults of both sexes.
