Have a look at our latest results on #CDK regulation, just posted as a pre-print! This study was spearheaded by PhD student Amy McGeoch. Amy has determined the #cryoEM structure of the CDK11-cyclin L-SAP30B complex, an important regulator of #spliceosome activation. www.biorxiv.org/content/10.6...
Depictions of the structure of CDK11-cyclin L-SAP30BP. Four cryo-EM densities are shown at the top, two molecules models at the bottom. CDK11 is green, cyclin L is purple, and SAP30BP is yellow.

Thrilled to share that our latest research on breaking the symmetry of designed protein cages has been featured on the cover of Protein Science's special issue on Protein Design! #proteincages #proteindesign #symmetrybreaking
Inspired by Hilma af Klint's The Swan, No. 8, the cover illustrates how we break the symmetry of a previously symmetric protein cage, pushing the boundaries of protein-based assemblies and expanding the design space.
In the image there is a group of protein cages distributed radially with a bigger one in the center of the image. The protein cage core is symmetric, but overall it is asymmetric, as it has a subunit (depicted in purple) that breaks the symmetry.
