Abstract
The formation of dynamic protein filaments contributes to various biological functions by clustering individual molecules together and enhancing their binding to ligands. We report such a propensity for the BTB domains of certain proteins from the ZBTB family, a large eukaryotic transcription factor family implicated in differentiation and cancer. Working with Xenopus laevis and human proteins, we solved the crystal structures of filaments formed by dimers of the BTB domains of ZBTB8A and ZBTB18 and demonstrated concentration-dependent higher-order assemblies of these dimers in solution. In cells, the BTB-domain filamentation supports clustering of full-length human ZBTB8A and ZBTB18 into dynamic nuclear foci and contributes to the ZBTB18-mediated repression of a reporter gene. The BTB domains of up to 21 human ZBTB family members and two related proteins, NACC1 and NACC2, are predicted to behave in a similar manner. Our results suggest that filamentation is a more common feature of transcription factors than is currently appreciated.

C-Terminal Binding Protein 2 Emerges as a Critical Player Linking Metabolic Imbalance to the Pathogenesis of Obesity. J Atheroscler Thromb 2024; 31:109-116.

Abstract
Metabolism is one of the vital functions of cells and living organisms, and the systems to sense and respond to the metabolic alterations play pivotal roles in a plethora of biological processes, including cell proliferative activities, immune cell functions, aging processes, and neuronal functions. Recently, we have reported that a transcriptional cofactor, C-terminal binding protein 2 (CtBP2), serves as a critical metabolite sensor in this context. CtBP2 has a structural pocket called Rossmann fold to accommodate metabolites, and it has been reported to be activated upon binding to NADH/NAD+. Owing to its preferential binding affinity for NADH compared with NAD+, increased glycolysis activates CtBP2 by regenerating NADH from NAD+. Furthermore, we recently reported that fatty acyl-CoAs, metabolites accumulated under the condition of lipid overload, as represented by obesity, can inactivate CtBP2. These observations suggest that CtBP2 monitors not only redox state but also energy substrate preference in the maintenance of metabolic homeostasis. In line with these metabolite-sensing capabilities, CtBP2 is activated in healthy subjects to protect against metabolic disturbances, whereas inactivation of CtBP2 in obesity contributes to the pathogeneses of obesity.This metabolic system orchestrated by CtBP2 can provide a novel framework for understanding how cells maintain their homeostasis through coordination of metabolism, and CtBP2 incapacitation can be a critical point of the obesogenic cascade.

Fragment Hopping-Based Design of Novel Biphenyl-DAPY Derivatives as Potent Non-Nucleoside Reverse Transcriptase Inhibitors Featuring Significantly Improved Anti-Resistance Efficacy.

Abstract
To enhance the anti-resistance efficacy of our previously reported non-nucleoside reverse transcriptase inhibitor (NNRTI) 4, a series of novel biphenyl-DAPY derivatives were developed using the fragment-hopping strategy. Most of the compounds 8a-v exhibited remarkably improved anti-HIV-1 potency. The most active compound 8r proved to be exceptionally potent against the wild-type HIV-1 (EC50 = 2.3 nM) and five mutant strains, such as K103N (EC50 = 8 nM) and E138K (EC50 = 6 nM), significantly better than 4. The new DAPY analogue was 8-fold less cytotoxic and had a 17-fold higher selectivity index (CC50 = 40.77 μM, SI > 17391) than etravirine and rilpivirine. Also, it displayed favorable pharmacokinetic properties with an oral bioavailability of 31.19% and weak sensitivity toward both CYP and hERG. No apparent acute toxicity (2 g/kg) and tissue damage occurred. These findings will further expand the possibility of successfully identifying biphenyl-DAPY analogues as highly potent, safe, and orally active NNRTIs for HIV treatment.
