@fxrico.bsky.social deleted the single BSU1 gene in Marchantia, resulting in a mass of undifferentiated cells & strong patterning defects. Cell cycle markers are highly active in the thallus. Our data point to a function for Kelch phosphatases in the cell cycle not in BR signaling (6/6).

In Andrea’s structure the C-terminal tail of BSU1 is phosphorylated and bound to the active site. Andrea and Pierre showed that this phosphorylation is caused by the CDK1-cyclin-CKS1 complex, very similar to PP1, where no structure is available. The phosphorylation inhibits BSU1 activity (5/6).

Oded and Felix Rico generated CRISPR/Cas9 knock-out mutants of all Kelch phosphatases in Arabidopsis. These mutants have a fertility defect, suggesting a function in embryo development, many more stomata than wild type, but wild type-like BR responses. (4/6)

BSU1 was originally identified in an activation tagging screen in the weak BR receptor mutant bri1-5. Oded Pri-Tal found, to our surprise, that also phosphatase-dead versions of the enzyme can rescue the bri1-5 mutant. A mutant in the RVxF substrate binding groove does not rescue. (3/6)

A crystal structure from Andrea Moretti of the Kelch phosphatase BSU1 reveals that it looks virtually identical to PP1, a Ser/Thr phosphatase involved in cell cycle regulation. Consistently, Pierre Raia could show that BSU1 is an efficient Ser/Thr, not a tyrosine phosphatase in vitro. (2/6)

Our new year starts of course with new preprint on brassinosteroid signaling tinyurl.com/nhzcfkxd. We re-analyzed the function of Kelch phosphatases, which were previously characterized as protein tyrosine phosphatases that dephosphorylate the critical pTyr200 in the GSK3 kinase BIN2. (1/6)
