I am excited to announce that I will be moving to IMB Mainz next year! The Winter call for the IPP PhD program is now open; if you are interested in maternal #mRNA regulation and #translation in early vertebrate development, please apply! Deadline: 16 October.
More info: www.imb.de/students-pos...
Delighted to share a chemical-genetic system we developed to rapidly inhibit a serine/threonine phosphatase complex (within secs). This will make it much easier to study #phosphatases. The system is also applicable to other “undruggable” enzymes.

Without PP2A-B55 or CDC14 cells enter mitosis earlier
This advance is independent of CDK activity regulation. This indicates that in the absence of these Ppases, critical CDK substrates can be phosphorylated at lower CDK activity levels (ie earlier), thus advancing mitotic entry.
What happens in the absence of the Ppases?
Using a fluorescent sensor, we showed that without PP2A-B55, a candidate substrate (Cut3-T19) is phosphorylated earlier and less rapidly.
This suggests that the identity of the Ppase that targets a CDK substrate site affects its phosphorylation timing. The exact phosphorylation timing of a given site is determined by a combination of factors.

Does the division of labour between the Ppase impact the timing of CDK substrate phosphorylation? Yes! ✅
Phosphoproteomic timecourse showed that CDK substrates targeted by CDC14 and PP2A-B56 are, on average, net phosphorylated first, followed by CDK substrates targeted by PP1 and then PP2A-B55.
Identifying some more Ppase substrates…
We also identified 3,000+ Ppase substrates phosphorylated by other kinases (not CDK). The identified Ppase motifs were similar to those identified in other eukaryotes, indicating conservation of Ppase substrate specificity.
Distinct Ppase targets
• PP2A-B55, B56, CDC14 & PP1 targeted specific subgroups of CDK sites
• <5% of sites were targeted by multiple Ppases
• Ppases had different preferences for amino acids
🔎 Identifying Ppase substrates
We used phosphoproteomics: inhibiting CDK with & without Ppase and tracking dephosphorylation. We classified a site as a Ppase substrate if it was dephosphorylated substantially slower in the absence of the Ppase.
❓Open questions
How do CDK-opposing Ppases (PP2A-B55, PP2A-B56, PP1 & CDC14) together influence the phosphorylation timing of CDK substrates?
To answer this, we first needed to identify which CDK substrate is targeted by which Ppase.
🔄 CDK-opposing Ppases
• Important at mitotic exit to dephosphorylate CDK substrates
• Ppases are also active during interphase ➡️ could affect phosphorylation timing
• But for the majority of CDK substrate sites, it is not known which Ppase targets it
⏰ The cell cycle is driven by reversible phosphorylations
Hundreds of proteins need to be phosphorylated at the right time by cyclin-dependent kinases (CDKs) to order cell cycle events. These phosphorylations are opposed by phosphatases (Ppases), such as PP2A-B55, PP2A-B56, PP1 & CDC14.
🚨New preprint🚨
How do phosphatases affect CDK substrate phosphorylation timing during the cell cycle?
We showed that substrates dephosphorylated by different Ppases are net phosphorylated at different times.
