Common Name:ZNT1
HGNC Symbol:SLC30A1
HGNC Description:solute carrier family 30 (zinc transporter), member 1
HGNC ID:11012
Chromosome:Chr.1(-): 211748381-211752099 GRCh37
OMIM Phenotype:None
Nucleotide RefSeq:NM_021194
Protein RefSeq:NP_067017
Evidence:Substrate In Vitro Evidence: 1. When transfected into a zinc-sensitive baby hamster kidney (BHK) cell line, ZNT1 conferred resistance to high levels of extracellular zinc. IHC revealed that ZNT1 localizes to the plasma membrane. Cells overexpressing ZNT1 were resistant to high concentrations of extracellular zinc and exhibited lower intracellular zinc levels (as measured by a metal-responsive reporter construct). Palmiter, RD; Findley, SD. EMBO J 1995 Feb15, 14(4):639-49. 2. ZNT1 is a rescue agent for cells maintained in very high extracellular zinc conditions (ZNT1 is an exporter). Cousins, RJ; McMahon, RJ. J Nutr 2000 May, 130 (5S suppl):1384S-7S (Review) PMID 10801948. Substrate In Vivo Evidence: 1. ZNT-1 is induced after transient forebrain ischemia in the gerbil (high levels of zinc in the neuronal area were either the reason for or the result of ZNT1 induction). Tsuda, M et al. J Neurosci 1997 Sept 1, 17(17):6678-84 PMID 9254680. 2. Intestinal ZNT1 mRNA increases when rats are fed a high zinc diet. McMahon, RJ; Cousins, RJ. PNAS 1998 Apr 28, 95(9):4841-6 PMID 9560190. Tissue Distribution Evidence: 1. ZNT1 is ubiquitously expressed. In the small intestine, ZNT1 is highly expressed in the duodenum and jejunum. Rat ZNT1 is localized at the basolateral surface of rat enterocytes lining the villi, indicating a ZNT1 function in zinc acquisition and/or retention. McMahon, RJ; Cousins, RJ. PNAS 1998 Apr 28, 95(9):4841-6 PMID 9560190.

GTEx Expression by Gene and Transcript

The heat map summarizes relative expression by tissue type at two levels of tissue detail, e.g., 'Brain' and 'Brain - Amygdala'. Choose among four calculated expression values, including mean and median RPKM values, and quantile normalized (QN) distributions of these values. (Note that differences between some distributions are subtle.) The coloring is relative to the mean of all displayed values. All values are log base 2. (See also PMT GTEx Expression Plotting.)
