High affinity copper uptake protein 1 (CTR1) is a protein that in humans is encoded by the SLC31A1 gene.{{cite journal | vauthors = Zhou B, Gitschier J | title = hCTR1: a human gene for copper uptake identified by complementation in yeast | journal = Proc Natl Acad Sci U S A | volume = 94 | issue = 14 | pages = 7481–6 |date=Aug 1997 | pmid = 9207117 | pmc = 23847 | doi =10.1073/pnas.94.14.7481 | bibcode = 1997PNAS...94.7481Z | doi-access = free }}{{cite web | title = Entrez Gene: SLC31A1 solute carrier family 31 (copper transporters), member 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=1317}}

Copper is an element essential for life, but excessive copper can be toxic or even lethal to the cell. Therefore, cells have developed sophisticated ways to maintain a critical copper balance, with the intake, export, and intracellular compartmentalization or buffering of copper strictly regulated. The 2 related genes ATP7A and ATP7B, responsible for the human diseases Menkes syndrome and Wilson disease, respectively, are involved in copper export. In S. cerevisiae, the copper uptake genes CTR1, CTR2, and CTR3 have been identified, and in human the CTR1 and CTR2 (MIM 603088) genes have been identified.

Clinical significance

In 2022, a new autosomal-recessive disease was discovered that is caused by mutations of the CTR1 gene.{{cite journal | vauthors = Batzios S, Tal G, DiStasio AT, Peng Y, Charalambous C, Nicolaides P, Kamsteeg EJ, Korman SH, Mandel H, Steinbach PJ, Yi L, Fair SR, Hester ME, Drousiotou A, Kaler SG | title = Newly identified disorder of copper metabolism caused by variants in CTR1, a high-affinity copper transporter | journal = Human Molecular Genetics | volume = 31| issue = 24| pages = 4121–4130| date = August 2022 | pmid = 35913762 | doi = 10.1093/hmg/ddac156 | url = | pmc = 9759326 }} The disease is characterized by profound deficiency of copper in the central nervous system and presents with infantile seizures and neurodegeneration.
