Magnesium transporter, MagT1 (Goytain and Quamme, 2005; Schmitz et al., 2007; Zhou and Clapham, 2009).  As of 2018, the function of this protein as a Mg2+ transporter was under debate (Schäffers et al. 2018).

Glycosyl transferase, Ost3 of 350 aas and 4 TMSs.  This protein is a subunit of the yeast oligosaccharyltransferase complex involved in N-glycosylation (Wild et al. 2018). It is not the catalytic subunit (see TC# 9.B.142.3.14).

*1.A.76.2.1









Oligosaccharyltransferase complex/magnesium transporter family protein of 173 aas and 3 or 4 TMSs. The proteins in this family are part of a complex of eight ER proteins that transfers core oligosaccharide from dolichol carrier to Asn-X-Ser/Thr motifs. This family includes both OST3 and OST6, each of which contains four predicted transmembrane helices. Disruption of OST3 and OST6 leads to a defect in the assembly of the complex. Hence, the function of these genes seems to be essential for recruiting a fully active complex necessary for efficient N-glycosylation.
