3.A.1.208.11
Vacuolar metal resistance and drug detoxification protein, yeast cadmium factor (YCF1 or Ycf1p), of 1515 aas and 15 or 16 TMSs in a 5 + 6 + 4 or 5 TMS arrangement; it transports cadmium-glutathione conjugates, glutathione S-conjugated leukotriene C4, organic glutathione S-conjugates, selenodigluthatione, unconjugated bilirubin, reduced glutathione, and diazaborine (Lazard et al., 2011). It mediates arsenite expulsion, possibly as a glutathione conjugate. Activity is dependent on Tus1p, a guanine nucleotide exchange factor (GEF) for the small GTPase Rho1p and a Rho1p-dependent-positive regulator of Ycf1p (Paumi et al. 2007). The structure of Ycf1p reveals the transmembrane domain TMD0 and the regulatory region of ABCC transporters (Bickers et al. 2021).
