Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: protein kinase activity; diacylglycerol binding; protein serine/threonine kinase activity.
There is experimental evidence that it is involved in the biological process: Ras protein signal transduction; tracheal outgrowth, open tracheal system; imaginal disc-derived wing morphogenesis; signal transduction.
45 alleles are reported.
The phenotypes of these alleles are annotated with: eye; photoreceptor cell; mesothoracic tergum; eye photoreceptor cell; wing; ommatidium.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Protein kinase C-like, phorbol ester/diacylglycerol binding; Protein kinase, ATP binding site; Protein kinase, catalytic domain; Protein kinase-like domain; Serine-threonine/tyrosine-protein kinase; Tyrosine-protein kinase, active site.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of low expression.
Peak expression observed within 00-18 hour embryonic stages, in adult female stages.
