HEC transcription factors control the timing of cell fate transitions in a dynamic stem cell system, allowing plants to adapt their developmental program to diverse environments.
Structural studies reveal the mechanism by which a HECT E3 ubiquitin ligase carries out E2-to-E3-to-substrate ubiquitin transfer and prioritizes target lysines for ubiquitination.

The unspliced HAC1 mRNA does not give rise to detectable protein in budding yeast, despite its cytoplasmic localization, due to a two-part post-transcriptional silencing mechanism.

Stochasticity introduced computationally into a gene expression oscillator creates heterogeneity in the time of differentiation of identical cells and offers robustness to the progenitor state and the outcome of cell division.

The proteins Heart of Glass (HEG1) and Rasip1 are both essential for cardiovascular development; and directly bind to each other to guide Rasip1 to endothelial cell junctions to support vascular integrity.
During meiosis, budding yeast use a checkpoint involving the protein Mec1 to prevent the formation of double-strand breaks in DNA that has not completed replication.

Bacteria that resist direct complement-mediated killing by pores can still potently activate the complement system and trigger release of incomplete pores into human serum.

RNA decay is used at multiple points in the budding yeast unfolded protein response to regulate its suppression and activation, and possibly its attenuation.
