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 Col9a1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- NC4 domain
- triple helical domain
- LamG
- protein homodimerization
- Collagen triple helix repeat (20 copies)
- protein binding
- carbohydrate binding
