The copper interacting protein Atx1, that could be a copper chaparone protein or a copper efflux protein.  It is of 70 aas with an N-terminal half that is more hydrophobic than the C-terminal half (Deng and Wang 2023).

HMA domain-containing protein of 81 aas.

Atx1 homolog of Glycine max (Soybean) (Glycine hispida)
9.B.462.1.3









Copper transport protein, ATX1, of 76 aas.

ATX1 of Arabidopsis thaliana (Mouse-ear cress)
9.B.462.1.4









Copper transport protein, CCH, of 121 aa

CCH of Arabidopsis thaliana
9.B.462.1.5









ATOX1 (HOH1) copper chaparone/transport protein of 78 aas amd 0 TMSs.  It is homologous to the N-terminal repeat sequences in Cu2+ ATPases (e.g., TC# 3.A.3.5.19; 28% identical and 51% similar).  However, the proteins in this family are single domain proteins.  Curcumin suppresses copper accumulation in non-small cell lung cancer by binding ATOX1 (Qin et al. 2024).
