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 tyrosine kinase activity.
There is experimental evidence that it is involved in the biological process: neuromuscular synaptic transmission; regulation of lamellipodium assembly; border follicle cell migration; synaptic vesicle endocytosis; actin filament depolymerization; bristle morphogenesis; mushroom body development.
7 alleles are reported.
The phenotypes of these alleles are annotated with 11 unique terms, many of which group under: organ system subdivision; organ system; multicellular structure; sense organ; adult segment; adult; external compound sense organ; peripheral nervous system; organelle; protocerebrum; actin cytoskeleton; acellular anatomical structure.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Actin-binding, cofilin/tropomyosin type.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderate expression.
Peak expression observed within 00-06 hour embryonic stages.
