3.A.1.210.7
The homodimeric heavy metal tolerance protein 1, CeHMT-1 (AbcB6) (exports phytochelatin ((γ-Glu-Cys)n)-Cd2+ complexes as well as glutathione complexes of copper and arsenic) (Vatamaniuk et al., 2005).  The N-terminal hydrophobic extension domain is required (but not sufficient) for dimerization and therefore is essential for normal function (Kim et al. 2010, Kim et al. 2018). Both the N- and C-terminal domains are required for proper localization in the endosomes of liver-like coelomocytes, head neurons and intestine (Kim et al. 2018).
