| Post Translational Modifications | O-Glycosylation at Thr-27 protects from proteolytic cleavage in the N-terminal extracellular domain. Proteolytic cleavage, leading to a truncated form, is facilitated by SLC31A2 and initiated preferentially by CTSL and to a minor extend by CTSB in endolysosomal compartments. In vitro, is cleaved by CTSL/cathepsin L between residues 8 and 9 from the amino terminus. A post-CTSL/cathepsin L processing occurs to yield to the fully truncated form. Sulfenylated at Cys-189 after stimulation with VEGFA, which induces SLC31A1-KDR disulfide bond formation and their co-internalization to early endosomes, driving to a sustained VEGFR2 signaling. |
| Function | High affinity copper uptake protein 1: 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. 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. 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. Truncated CTR1 form: Mobilizes copper(1+) out of the endosomal compartment, making copper(1+) available for export out of the cells. |
