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.

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.

Structural basis of T-loop–independent recognition and activation of CDKs by the CDK-activating kinase Cyclin-dependent kinases (CDKs) are prototypical regulators of the cell cycle. The CDK-activating kinase (CAK) acts as a master regulator of CDK activity by catalyzing the activating phosphorylation o...

Now out in Science! Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In @vcushing.bsky.social's magnum opus, we use #cryoEM to figure out how the CDK-activating kinase recognises CDKs to fully activate them - a key step in cell cycle control.

Resistance to CDK7 inhibitors directed by acquired mutation of a conserved residue in cancer cells
Laki Buluwela @simak.bsky.social @bjgreber.bsky.social et al find a single base change of #CDK7 conferring resistance to non-covalent CDK inhibition in prostate cancer

We show a single amino acid change in CDK7 causes acquired resistance to CDK7i in cancer cells. There are implications for patient selection,resistance monitoring and switching treatments. thanks to @vcushing.bsky.social @bjgreber.bsky.social @prostatecanceruk.bsky.social

High-throughput investigation of cyclin docking interactions reveals the complexity of motif binding determinants - Nature Communications Many protein–protein interactions depend on Short Linear Motifs (SLiMs). In this study, the authors use large-scale binding assays, deep mutational scanning, and structural analysis to map SLiMs recog...

Just published: Our paper on high-throughput analysis of cyclin docking interactions, led by the group of Norman Davey @icr.ac.uk and with some small-complex-plus-peptide #cryoEM by @natalia-mg.bsky.social from my lab. Congratulations, everyone!

TFIIH kinase CDK7 drives cell proliferation through a common core transcription factor network CDK7 kinase activity is found to control RNAPII transcription through a cohort of TFs that drive cell cycle and proliferation.

For our latest paper, we worked with SYROS Pharmaceuticals, the groups of Dylan Taatjes and Robin Dowell at CU Boulder, and @abhaykot.bsky.social. Junjie Feng in my lab determined the #cryoEM structure of the CDK7 inhibitor SY5609 bound to its target...

High-throughput discovery and deep characterization of cyclin-CDK docking motifs Cyclin-CDKs are master regulators of cell division. In addition to directly activating the CDK, the cyclin subunit regulates CDK specificity by binding short peptide “docking” motifs in CDK substrates...

New pre-print! To support a CDK-cyclin docking motif discovery and characterisation project led by Norman Davey and colleagues, @natalia-mg.bsky.social in my lab determined the #cryoEM structures of three peptide-bound CDK2-cyclin A complexes. Check it out!
