The Pkpk and Pksple isoforms of the Prickle protein determine right- or left-handed bristle morphogenesis by coupling Frizzled/Vang signaling to the Fat/Dachsous PCP directional signal in opposite directions.
A cytokine partly derived from macrophages is required to promote normal muscle health and metabolism by inhibiting the activity of the insulin signalling pathway in the fruitfly Drosophila melanogaster.
Carotenoids are not just required as core components for plastid biogenesis, they can be cleaved into an apocarotenoid signal that regulates etioplast and chloroplast development during extended periods of darkness.
The transcription factor Lola is defined as a non-canonical Hippo signaling component essential for Drosophila midgut homeostasis via its interaction with Warts and suppression on Dref and SkpA expression levels.
Cryo-electron microscopy structures, combined with biochemical experiments, show how the E. coli F element-encoded TraR protein regulates transcription initiation by altering RNA polymerase conformation and conformational heterogeneity.
Telophase reorientation corrects errors in spindle orientation that persist after imprecise initial spindle positioning during early mitosis, and contributes to balancing self-renewal with differentiation during epidermal development.
