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 Spag1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

  • Tetratricopeptide repeats
  • mitochondrial import receptor subunit TOM70
  • tetratricopeptide repeat
  • Potential Monad-binding region of RPAP3
