Enzyme may get key role in drug design for breast cancer and brain condition
Share

In recent years, researchers have focussed on the enzyme TLK2 suspecting it of playing a main role in several diseases. A new study conducted at the University of Copenhagen now reveals that the enzyme displays lower levels of activity in intellectual disability and that it is possible to inhibit it in breast cancer, where it is overactive. The study thus suggests that the enzyme may be a target for potential therapies.

In order to maintain genome stability in the cells the enzyme TLK2 constantly strives to attach phosphate to proteins. It activates specific functions in the cell and helps to stabilise the cell nucleus, which is of critical importance.

In recent years the enzyme has been linked to various diseases. For example, researchers have discovered that the gene coding for the enzyme is overexpressed in patients suffering from ER-positive breast cancer and mutated in intellectual disability, but up until now no one has been able to outline the behaviour of the enzyme.

Now researchers from the University of Copenhagen and Institute for Research in Biomedicine Barcelona have taken a big step forwards and managed to outline the enzyme all the way to the molecular level using X-ray crystallography. Their
