Dating Mammalian Evolution

Fri, 28 Mar 2014 15:14:37 +0000

When the age of the dinosaurs ended around 65 million years ago, mammals stepped in to fill the gap, and the age of the placentals began. However, whether early placental mammals were already present on Earth before the demise of the dinosaurs has been the subject of a long standing debate. Recent research in GEE [...]

The Delicate Balance of Effect and Response

Tue, 18 Feb 2014 11:50:36 +0000

We may not always be aware of it, but many wild plants, animals, fungi and even bacteria, provide crucial services to us which keep the ecosystems of Earth functioning. Environmental changes caused by human activities are now threatening many species, and those that cannot withstand these changes may be lost forever, potentially taking the services [...]

It’s All in the Wrist

Fri, 20 Dec 2013 16:18:20 +0000

The evolution of the primate wrist has been dramatic, enabling primates to adapt to a wide variety of lifestyles and walking styles, including tree-swinging, climbing and terrestrial walking both on four legs and two. In hominids, the evolution of the bipedal gait freed up the forelimbs for tool use, and the wrist evolved independently from [...]

The Transcriptional Profile of A ‘Wingman’

Wed, 27 Nov 2013 14:25:48 +0000

In many species, males have special adaptations to attract females. From antlers to stalk-eyes, to bright plumage and beards, males across the animal kingdom work hard to look attractive to the opposite sex. In some species, looking good isn’t enough, though. Male wild turkeys need a less attractive ‘wingman’ to help him attract a woman. [...]

Damage and Fidelity: The Role of the Female Germline in mtDNA Inheritance

Mon, 11 Nov 2013 15:13:12 +0000

Billions of years ago, one single-celled organism engulfed another, beginning a symbiotic interaction that would change live on Earth forever. The mitochondria are what remains of this symbiotic event, and are responsible for producing energy in all eukaryotic cells. Derived from a free-living organism, they carry their own genes, but these genes are at risk [...]

Dr Michal Malecki (Bahler Group) awarded prestigious Newton International Fellowship

15 January 2014

Michal Malecki

Dr Michal Malecki has recently secured a prestigious Newton International Fellowship which is jointly run by The British Academy and the Royal Society. This postdoctoral fellowship is to work on the function of cytoplasmic non-canonical RNA polymerases in fission yeast.

Non-canonical RNA polymerases (ncPAPs) modify RNA molecules by adding nucleotides to their 3’-ends without the need of a starter or template. Modifications catalyzed by ncPAPs have different consequences on RNA fate: they can destabilize and rapidly degrade transcripts, but they can also stabilize transripts, facilitate processing steps, or regulate translation ability. The ability to modify pre-existing RNAs makes ncPAPs ideal candidates for shaping the transcriptome at a post-transcriptional level.


The role of ncPAPs in RNA metabolism has recently started to be investigated. There are still many unsolved questions, most notably concerning the function of ncPAPs in the cytoplasm. In humans, cytoplasmic ncPAPs investigated so far affect cellular differentiation, senescence, synaptic plasticity, aging, and may be important in tumor suppression. The human genome codes for seven potential ncPAPs, with functions in both the cytoplasm and nucleus. The genome of fission yeast (Schizosaccharomyces pombe) encodes six potential ncPAPs, which makes it a highly attractive organism to investigate the functions of these intriguing proteins.


Four out of six S. pombe ncPAPs localise in the cytoplasm or both in the nucleus and cytoplasm. To study the function of these four cytoplasmic ncPAPs, we will apply multiple genetic, genomic and biochemical approaches, and then integrate the resulting data for insight into general biological principles.
