Summary Information

Automatically generated summary

See sections below for more information

The gene tumbleweed is referred to in FlyBase by the symbol tum (CG13345, FBgn0086356). It has the cytological map location 50C6. Its sequence location is 2R:9743648..9746222. Its molecular function is described as: Rho GTPase activator activity; GTPase activator activity; diacylglycerol binding; signal transducer activity. It is involved in the biological processes: dendrite morphogenesis; neuron development; Rho protein signal transduction; cell proliferation; negative regulation of Wnt receptor signaling pathway; cytokinesis; mitotic spindle organization and biogenesis. 27 alleles are reported. The phenotypes of these alleles are annotated with 18 unique terms, many of which group under: adult segment; organ system; nervous system; adult brain; peripheral nervous system; adult mesothoracic segment; thoracic segment; cuticle; cell cycle; dorsal thoracic disc; contractile ring; wing hair. It has one annotated transcript and one annotated polypeptide.
