Summary: Enables calcium ion transmembrane transporter activity and manganese ion transmembrane transporter activity. Involved in intracellular monoatomic cation homeostasis and monoatomic cation transmembrane transport. Located in Golgi medial cisterna; cis-Golgi network; and fungal-type vacuole. Used to study congenital disorder of glycosylation type II and congenital disorder of glycosylation type IIk. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation type IIk. Orthologous to human TMEM165 (transmembrane protein 165).

What's a GeneRIF?

obtained first evidence that Gdt1p from yeast directly transports manganese, which strongly reinforces the suggested link between the UPF0016 family and Mn(2+) homeostasis
Title: The yeast protein Gdt1p transports Mn(2+) ions and thereby regulates manganese homeostasis in the Golgi.
Erd1 transports Pi in the opposite direction from XPR1 and other EXS family proteins and facilitates byproduct removal from the Golgi complex together with Gdt1
Title: H(+) and Pi Byproducts of Glycosylation Affect Ca(2+) Homeostasis and Are Retrieved from the Golgi Complex by Homologs of TMEM165 and XPR1.
Gdt1p,to sustain the Golgi glycosylation process, imports Mn(2+) inside the Golgi lumen when Pmr1p exclusively transports Ca(2+). Gdt1p is a Mn(2+)-sensitive protein whose abundance dependents on the kind of the ion transported by Pmr1p. The aspartic residues of the 2 conserved motifs E-x-G-D-[KR], in the cation binding sites of Gdt1p, play a role in Golgi glycosylation and hence in Mn(2+)/Ca(2+)transport.
Title: Investigating the function of Gdt1p in yeast Golgi glycosylation.
Gdt1p controls cellular calcium stores and plays a major role in the calcium response induced by osmotic shock when the Golgi calcium pump, Pmr1p, is absent. Furthermore, in the presence of a high concentration of external calcium, Gdt1p is required for glycosylation of carboxypeptidase Y and the glucanosyltransferase Gas1p.
Title: Yeast Gdt1 is a Golgi-localized calcium transporter required for stress-induced calcium signaling and protein glycosylation.
