Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: sodium:potassium-exchanging ATPase activity; cation transmembrane transporter activity.
There is experimental evidence that it is involved in the biological process: regulation of tube diameter, open tracheal system; regulation of tube size, open tracheal system; establishment of glial blood-brain barrier; open tracheal system development; regulation of tube length, open tracheal system; cation transport; septate junction assembly.
25 alleles are reported.
The phenotypes of these alleles are annotated with: tracheal branch primordium; presumptive embryonic salivary gland; trichogen cell; embryonic somatic muscle; embryonic/larval dorsal trunk; septate junction; embryonic/larval tracheal system; dorsal trunk primordium; embryonic/larval transverse connective; ganglionic branch primordium.
It has 5 annotated transcripts and 5 annotated polypeptides.
Protein features are: ATPase, P-type cation exchange, beta subunit.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of very low expression.
Peak expression observed within 06-24 hour embryonic stages, during early larval stages, at stages throughout the pupal period, in adult male stages.
