A unique form of regulation has been observed in the unfolded protein response of S. pombe, along with a novel mechanism of post-transcriptional mRNA processing.
The development of colonies of cells in choanoflagellates, water-dwelling organisms that feed on bacteria, is triggered by the presence of very low concentrations of a lipid molecule produced by certain types of bacteria.

The transcription machinery used to regulate gene expression and self-renewal in human embryonic stem cells is different from that found in other cells.
A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.
A combination of molecular dynamics simulations and X-ray diffraction data has been used to construct more realistic models of proteins and to provide new insights into their interactions with other proteins and biomolecules.

A protein that can recognize regions of DNA with a high proportion of unmethylated CpG dinucleotides, and then recruit polycomb group proteins to these CpG islands, has been identified.
The ability of epithelial cells to distinguish between domains on opposing cell surfaces within a tissue, a property known as planar cell polarity, relies on proteins and protein complexes directing the traffic of signaling proteins to specific locations on the cell surface membrane.
