The Broad-complex, Tramtrack, and Bric-à-brac/poxvirus and zinc finger (BTB/POZ) domain is crucial for protein interactions in development and cancer. This review updates its classification and discusses structural principles of BTB-mediated interactions.
Area of Science:
- Biochemistry
- Structural Biology
- Evolutionary Biology
Background:
- The Broad-complex, Tramtrack, and Bric-à-brac/poxvirus and zinc finger (BTB/POZ) domain is a conserved eukaryotic protein motif.
- BTB/POZ domains are implicated in crucial developmental processes and oncological diseases.
- These domains mediate protein-protein interactions and can form multimers.
Conclusions:
- BTB/POZ domains exhibit diverse structural interfaces for specific protein interactions.
- Structural insights provide a basis for targeted inhibition of BTB/POZ-mediated functions.
- Understanding BTB/POZ domain evolution clarifies their roles in biological processes and disease.
