The actual residues in the relevant transmembrane domains (TM9 and TM12) are not conserved in the eukaryotic homologues. Authors are not 100% sure because crosslinking the protein in a lipid bilayer has not been performed.

Regarding the bond order difference for the C5-C6 bond, the authors used the topology and parameter files derived from the small molecule crystal structures of clomipramine and imipramine rather than theoretical values.
The biological unit is the monomer, which is the asymmetric unit. A crystallographic dimer can be generated, but its physiological relevance is not yet known.
