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 Ap3b2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- appendage domain
- Clathrin-adaptor complex-3 beta-1 subunit C-terminal
- ear domain
- hinge domain
- Adaptin N terminal region
- HEAT repeats
