Gaining genetic control over neural modules that drive the grooming of each Drosophila body part reveals how mechanisms for selecting among competing behavioral choices are used to generate sequences of actions.
The hepatic endocannabinoid/CB1R system controls the soluble leptin receptor’s expression and/or subsequent release by Trib3-induced regulation of C/EBP homologous protein levels in hepatocytes to affect leptin signaling in the liver.
The engagement of DNA crossings is shown to license ATP hydrolysis and DNA cleavage by topoisomerase VI, a finding with mechanistic ramifications for related GHKL ATPases and meiotic recombination machineries.
A mutant impaired for ribosome recycling exhibits translational reprogramming wherein strong mRNAs outcompete weak mRNAs, also observed when preinitiation complexes are diminished by eIF2α phosphorylation or 40S ribosomal subunit depletion.
A grooming sequence is produced by a neural architecture that readies different movements simultaneously, and a mechanism where prioritized suppression between the movements determines their sequential performance.
