Seipin oligomers dynamically interact with small, nascent lipid droplets near the endoplasmic reticulum to convert them into larger, mature lipid droplets in a newly identified step of lipid droplet formation.
Endothelial cells express a soluble isoform of the L1CAM cell adhesion molecule that is generated by the splicing factor NOVA2 and induces angiogenesis, with relevant implications for ovarian cancer vascularization.
The balance between sleep and sex drives determines whether male flies sleep or court, and a subset of octopaminergic neurons interact with the Fruitless-expressing courtship circuit to suppress sleep for sustained courtship.
The messenger RNA encoding La-related protein-4 (LARP4) contains a short region of instability whose codon clusters are sensitive to low abundance tRNAs that when elevated increase LARP4 activity for poly(A) lengthening of ribosomal protein mRNAs and other mRNAs.
Dissection of a cis-regulatory element (CRM) in its native chromosomal context using CRISPR/Cas9 editing and novel 'Active Genetics' reveals new features of CRM function and insights into how such regulatory elements change during evolution.
Tuned protein–protein interaction affinity optimizes the repressive function of the ETS family transcription factor Yan in order to contribute specificity and robustness to cell fate specification in the developing Drosophila eye.
Evidence that the small GUY1 protein is a strong candidate for being a male-determining factor is provided via the establishment of Guy1 transgenic lines of mosquitoes that confer complete and stable female lethality.
