AI Article Synopsis
- The Wnt signaling pathway's activation is primarily controlled by the regulation of β-catenin turnover.
- In early embryos of Xenopus laevis, all pathway components are present, and egg extracts can mimic various biological processes.
- This study presents a method to analyze β-catenin degradation using radiolabeled and luciferase-fusion proteins, highlighting the role of Wnt pathway components and small molecules in regulating β-catenin levels.
Article Abstract
The regulation of β-catenin turnover is the central mechanism governing activation of the Wnt signaling pathway. All components of the pathway are present in the early embryo of Xenopus laevis, and Xenopus egg extracts have been used to recapitulate complex biological reactions such as microtubule dynamics, DNA replication, chromatin assembly, and phases of the cell cycle. Herein, we describe a biochemical method for analyzing β-catenin degradation using radiolabeled and luciferase-fusion proteins in Xenopus egg extracts. We show that in such a biochemical system, cytoplasmic β-catenin degradation is regulated by soluble components of the Wnt pathway as well as small molecules.

The formation of biomolecular condensates contributes to intracellular compartmentalization, and plays an important role in many cellular processes. The characterization of condensates is however challenging, requiring advanced biophysical or biochemical methods that are often less suitable for in vivo studies. A particular need for easily accessible yet thorough methods that enable the characterization of condensates across different experimental systems thus remains.

Various DNA damage checkpoint control mechanisms in eukaryotic cells help maintain genomic integrity. Among these, NBS1, a key component of the MRE11-RAD50-NBS1 (MRN) complex, is an essential protein involved in the DNA damage response (DDR). In this study, we discovered that DNA damage-binding protein 1 (DDB1) interacts with NBS1.

Plant cation-chloride cotransporters (CCCs) are proposed to be Na-K-2Cl transporting membrane proteins, although evolutionarily, they associate more closely with K-Cl cotransporters (KCCs). Here, we investigated grapevine ( L.) VvCCC using 3D protein modeling, bioinformatics, and electrophysiology with a heterologously expressed protein.

Article Synopsis
- * EAAT2 dysfunction is linked to several neurodegenerative diseases, including Alzheimer's and Parkinson's, with specific mutations in LRRK2, particularly Gly2019Ser, reducing EAAT2 expression.
- * This study reveals that LRRK2 is essential for the stability and function of EAAT2, suggesting its role in preventing neuronal damage from excessive excitatory signals, but does not affect the function of other NTTs.
