SLC31A1 — Solute carrier family 31 member 1
SLC31A1 belongs to a gene co-expression module in 1 of 28 SCUBA cell types. Each module groups genes that rise and fall together in that cell type; the genes it shares a module with are its closest co-expression partners there.

Function
Uniporter that mediates the transport of copper(1+) from the extracellular space to the cytoplasm, across the plasma membrane and delivers directly copper(1+) to specific chaperone such as ATOX1, via a copper(1+)- mediated transient interaction between the C-terminal domain and a copper(1+) chaperone, thus controlling intracellular copper(1+) levels. May function in copper(1+) import from the apical membrane thus may drive intestinal copper absorption (By similarity). The copper(1+) transport mechanism is sodium-independent, saturable and of high-affinity. Also mediates the uptake of silver(1+). May function in the influx of the platinum- containing chemotherapeutic agents. The platinum-containing chemotherapeutic agents uptake is saturable (By similarity). In vitro, mediates the transport of cadmium(2+) into cells. Also participates in the first step of copper(2+) acquisition by cells through a direct transfer of copper(2+) from copper(2+) carriers in blood, such as ALB to the N-terminal domain of SLC31A1, leading to copper(2+) reduction and probably followed by copper(1+) stabilization. In addition, functions as a redox sensor to promote angiogenesis in endothelial cells, in a copper(1+) transport independent manner, by transmitting the VEGF- induced ROS signal through a sulfenylation at Cys-189 leadin g to a subsequent disulfide bond formation between SLC31A1 and KDR. The SLC31A1-KDR complex is then co-internalized to early endosomes, driving a sustained VEGFR2 signaling. Mobilizes copper(1+) out of the endosomal compartment, making copper(1+) available for export out of the cells
