ZT_dimer is the dimerisation region of the whole molecule of zinc transporters since the full-length members form a homodimer during activity. The domain lies within the cytoplasm and exhibits an overall structural similarity with the copper metallochaperone Hah1 UniProtKB:O00244, exhibiting an open alpha-beta domain with two alpha helices (H1 and H2) aligned on one side and a three-stranded mixed beta-sheet (S1 to S3) on the other side. The N-terminal part of the members is the Cation_efflux family, Pfam:PF01545 [1].	Domain
