Happy to share our recent work published in JPCL. We found more than 40% IDRs in human spliceosome crucial for various biological functions and are enriched in cancer-associated mutations. Thanks to all authors @BrunoPOS @LucaG @IsabellaFelli @magistratolab.bsky.social @rpierattelli.bsky.social

Congratulations Dan!

Reduced binding of Tau(210–240) to BIN1: Phosphate charges prefer n-Src/distal loops over RT-Src loops Within the disordered tangles of Tau is a proline-rich region, which is selectively targeted by the SH3 domain of BIN1, a known genetic factor for Alz…

Congratulations to @aminagaffour.bsky.social for getting our results into the Tau protein, and its subsequent binding to BIN1! It was a lot of work in the progress and I am very happy to get our research out. @idpnmrlab.bsky.social @krishnendubera.bsky.social

New Insecticide Designed to Target Ecdysone Receptors of Bemisia tabaci Bemisia tabaci is a highly destructive pest that affects many crops worldwide. Its feeding behavior on phloem sap and secretion of honeydew on leaves leads to the accumulation of mold, which impairs photosynthesis and fruit quality. Additionally, it transmits more than 100 plant viruses, which interfere with plant growth and reduce crop productivity. In this work, we targeted the ecdysone receptor (EcR) of B. tabaci, as it is involved in metamorphosis, cell differentiation, and reproduction processes. The EcR sequence was retrieved from the UniProt database (A0A142K0N3), and multiple sequence alignment (MSA) revealed that the ligand-binding domain is conserved among other plant-destroying pests and insects. The EcR structure of B. tabaci (PDB ID: 1Z5X) was used for high-throughput virtual screening with 32,552 secondary metabolites, retrieved from the NPAtlas 2.0 database using iDock 2.2.3. The top 40 metabolites were selected based on their predicted binding energy by iDock 2.2.3 and redocked using AutoDock Vina 1.1.2. The complexes of the top four compounds with EcR were selected for molecular dynamics simulation (total simulation time: 0.5 μs) and compared with the apo-EcR structure. Additionally, umbrella sampling simulations were performed for 1.64 μs. The insecticide-like properties and toxicity of the four metabolites were compared with conventional pesticides such as ponasterone A. Our computational predictions suggest that NPA008492, NPA006374, NPA012964, and NPA012752 are potential lead molecules and promising candidates for experimental validation.
