SLC13A5
Solute carrier family 13 (sodium-dependent citrate transporter), member 5 also known as the Na+/citrate cotransporter or mIndy is a protein that in humans is encoded by the SLC13A5 gene.[5] It is the mammalian homolog of the fly Indy (gene).
Function
SLC13A5 is a tricarboxylate plasma transporter with a preference for citrate.[5]
Clinical significance
In 2014, by means of exome sequencing it was determined that a genetic mutation of the SLC13A5 gene is the cause of an extremely rare citrate transporter disorder.[6] Mutations in SLC13A5 cause autosomal recessive epileptic encephalopathy with seizure onset in the first days of life.[6] Those afflicted suffer from seizures, global developmental delay, movement disorder and hypotonia.
Reduced expression of this gene is associated with longer lifespan in many organisms, including some non-human primates. Increased expression is associated with type 2 diabetes and non-alcoholic fatty liver disease. A sugary diet upregulates the expression of the gene, and so does Interleukin 6 signaling.[7]
