Excited to share 2 preprints, together showing how mechanisms of a molecular glue & E3 ligase cancer mutations serendipitously converge to cause neomorphic protein degradation in distinct contexts. Highlights below: 1/17

we report a direct TR-FRET-based protein quantification strategy (<1 h from lysis➡️read) in unmodified cell lines. If you're into PROTACs, and you hate running Westerns, check it out! Mini-thread: (1/n)
KYMERA THERAPEUTICS, INC - WO2024030628 - DEUTERATED STAT3 DEGRADERS AND USES THEREOF
If that generic structure doesn't give you a seizure I am not sure what will
Today we report in
@nchembio
the development of CoraFluors, a versatile & accessible class of TR-FRET probes for chemogenomic applications (thread below).
Very happy to share the final version of our manuscript in
@CellChemBiol
. We developed a new assay strategy to both quantify target proteins & measure TE of small molecules - all using endogenous protein in lysates from unmodified cell lines. Oh, and it only takes 1 h ⌚️✅ (1/3)
Are you working in TPD/
#PROTAC
-development and would welcome a simpler, faster, higher throughput way to quantify the abundance of endogenous target proteins directly in cell lysates, while getting a sensitive target engagement assay for ligand characterization for🆓?
Our paper is now online in its final form (
@CellChemBiol
)! We show that the isoform and complex selectivity of HDAC inhibitors is governed by dynamic process in cellular contexts (1/2).
If you liked the versatile TR-FRET methodology we reported in our cyclimid paper, check out our detailed
@STARProtocols
procedures. We are looking forward to seeing these approaches being (hopefully) broadly adapted!

#CoraFluor
labeled nanobodies. Pick your favorite flavor and make TR-FRET easier than ever.

Preprint out!
KEAP1-CUL3 structure, an awesome new assay platform for BTB domain-containing proteins, and elucidating the mode of inhibition of CDDO...what a fantastic collaboration

The cover of our November issue () features a class of luminescent terbium-based probes called CoraFluors () used for detecting ligand-bound protein targets by TR-FRET.

@Thundercat
Well if you activate the nuclear flux capacitor and subsequently redirect power from the radiative energy coupler then yeah I would be obliged to agree
Ok, ignoring the very much insane alchemy here (kudos to all authors!), am I the only one who's thinking...man, separating target molecule from starting material has to be an absolute pain!
Today we report a new strategy for C-to-N atom replacement in heterocycles. Led by

Am I the only one who takes pride in guessing which journal a preprint article has been submitted to, solely by looking at the formatting of the manuscript? e.g., # of figures, capital vs lower case letters in fig. panels, use of “extended data” (easy Nature family identifier)
We have a new preprint out on kinetic evaluation of selected
#HDAC
inhibitors. The data by
@CarlosMYruela
suggest that the reportedly HDAC3-selective inhibitor, RGFP966, is virtually equipotent against HDACs 1–3, exhibiting slow-binding

would be to have OPTIONAL (!) plastic silverware. I feel like 90+ percent of it that gets included with orders never gets used 👎🏻
Two birds with one stone: using clever biochemistry principles and a single POI-targeting antibody, we can rapidly & quantitatively measure both endogenous target engagement and protein levels in whole cell extracts, here exemplified for BRD4 (2/n)
