This molecule in its biological context is the C-terminal domain of the HIV RT protein. It can run as either a monomer or dimer on gel filtration. In the crystal structure it has formed a domain-swapped dimer with the C-terminal helix-strand swapping between two monomers. In the crystal structure two domain-swapped dimers come together to form what looks like a tetramer.
