Summary: Enables hormone activity. Involved in several processes, including determination of adult lifespan; neuron differentiation; and positive regulation of neuroblast proliferation. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including adult brain; adult gut; fat body; gut section; and imaginal disc. Human ortholog(s) of this gene implicated in several diseases, including Behcet's disease; artery disease (multiple); bone disease (multiple); carcinoma (multiple); and lung disease (multiple). Orthologous to human TGFB1 (transforming growth factor beta 1). [provided by Alliance of Genome Resources, Jan 2025]

What's a GeneRIF?

Loss of Dawdle causes major alterations in larval metabolic activity, including accumulation of tricarboxylic acid cycle intermediates, acidification of hemolymph, and misregulation of insulin signaling and nuclear-encoded mitochondrial gene expression.
Title: Systemic Activin signaling independently regulates sugar homeostasis, cellular metabolism, and pH balance in Drosophila melanogaster.
dawdle is activated by Gram-positive bacterial infection but repressed by Gram-negative infection or wounding; its role is to limit infection-induced melanization. Flies lacking dawdle function exhibit melanization even when uninfected.
Title: Multiple TGF-β superfamily signals modulate the adult Drosophila immune response.
Study shows that the Daw/Babo pathway acts upstream of gbb, and is involved in maintenance of muscle gbb expression.
Title: Activin signaling functions upstream of Gbb to regulate synaptic growth at the Drosophila neuromuscular junction.
Dawdle, one of four Activin-type ligands in Drosophila, preferentially signals through Babo(c), one of three isoforms of the Activin Type-I receptor that are expressed during development.
Title: The Drosophila Activin-like ligand Dawdle signals preferentially through one isoform of the Type-I receptor Baboon.
These results suggest that the Activin signaling pathway is required for producing the proper number of neurons to enable normal connection of incoming photoreceptor axons to their targets.
Title: Drosophila Activin- and the Activin-like product Dawdle function redundantly to regulate proliferation in the larval brain.
Results indicate that Daw functions in a permissive manner to modulate or enable the growth cone response to other restricted guidance cues, and support a novel role for activin signaling in axon guidance.
Title: The divergent TGF-beta ligand Dawdle utilizes an activin pathway to influence axon guidance in Drosophila.
Study suggests that by activating Daw and perhaps other TGF-beta ligands, tolloid related provides a permissive signal for axon guidance.
Title: The metalloprotease tolloid-related and its TGF-beta-like substrate Dawdle regulate Drosophila motoneuron axon guidance.
