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 human IGHA1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- Fc alpha1 domain
- Fc alpha2 domain
- CH2 domain (from immunoglobulin)
- CH1 domain (from immunoglobulin)
- cytoplasmic domain
- CH3 domain (from immunoglobulin)
- transmembrane domain
- hinge domain
- receptor binding
- Fc domain
