Axin scaffold protein interactions are crucial in Wnt signaling and human diseases. Targeting these protein-protein interactions (PPIs) offers promising new therapeutic strategies for cancer and other Wnt-driven conditions.

Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Oncology

Background:

  • Axin is a scaffold protein regulating multiple signaling pathways, notably as a negative regulator of the Wnt/β-catenin pathway.
  • Dysregulation of Axin and the Wnt/β-catenin pathway is implicated in various human cancers.
  • Current therapeutic targets in this pathway are limited, particularly enzymes, highlighting a need for novel strategies.

Purpose of the Study:

  • To review the Axin protein-protein interaction (PPI) networks across different signaling pathways, with a focus on Wnt signaling.
  • To discuss the role of Axin-interacting proteins in modulating signaling pathways relevant to human diseases.
  • To explore Axin PPI networks as a source for novel drug targets and therapeutic strategies.

Main Methods:

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Protein-protein Interfaces02:04

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Cytoskeletal Accessory Proteins

The cytoskeleton is an essential cell component that plays several structural and functional roles. However, the filaments that make up the cytoskeleton cannot function independently and depend on the accessory or ancillary proteins to effectively carry out their function. Accessory proteins associate with cytoskeletal filaments and their monomers, aiding filament formation and function. They also help in the cross-communication among cytoskeletal filaments. Cytoskeletal accessory proteins are...

Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
