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 HITS-CLIP sequencing method is used to demonstrate that cryptic exons can detect messenger RNA that contains nonsense mutations, and then cause this RNA to decay, which shows that these exons are involved in maintaining the electrical balance of neurons and, possibly, preventing epilepsy.
The structure of the recombination complex responsible for flagellar antigen switching in Salmonella enterica, and the mechanism that regulates the site-specific DNA inversion reaction, have been determined.
The simultaneous monitoring of transcription, translational control, protein production and proteolysis in the same system can improve our understanding of how cancer cells respond to chemotherapy.
A normally cytoplasmic deacetylase, Hdac6, localizes to the nucleus in embryonic stem cells, where it regulates the essential Tip60-p400 chromatin remodeling complex.
A deubiquitinase antagonizes the activity of an associated E3 ligase to prevent uncontrolled ubiquitination of a degradation machinery protein and thus maintain its functionality in protein quality control at the endoplasmic reticulum.
Two GAP proteins bound to mitochondria regulate the enyzme Rab7, and thereby the expansion of the isolation membrane during mitophagy, downstream of PINK1 and Parkin, two proteins that are mutated in familial Parkinson's disease.
