Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Smg5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- conserved domain
- ubiquitin protein ligase binding
- Telomerase activating protein Est1
- protein phosphatase binding
- Large family of predicted nucleotide-binding domains
- histone deacetylase binding
- protein binding
- PIN (PilT N terminus) domain: Superfamily
- telomeric DNA binding
- RNA binding
