Descripción

General description

Research area: Cancer


The gene AK1 (adenylate kinase isoenzyme 1) is mapped to human chromosome 9 on the location 9q34.11. It belongs to the nucleotide monophosphate kinase family. The AK1 protein is found in the cytosol of skeletal muscle, brain, and heart.The structure of AKs (adenylate kinases) comprises of three functional domains: the catalytic and oligomerization regulatory enzyme (CORE) domain, the ligand interaction domain (LID) domain, and the substrate binding site. In human tissues, a total of nine distinct isoenzymes of adenylate kinase are known, namely AK1 to AK9. Recombinant human AK1 protein, fused to His-tag at N-terminus, was expressed in Escherichia coli and purified by using conventional chromatography.

Biochem/physiol Actions

AK1 (adenylate kinase isoenzyme 1) is an enzyme involved in regulating the adenine nucleotide composition within a cell by catalyzing the reversible transfer of the terminal phosphate group between ATP and AMP. Low levels of AK1 cause imbalance in adenine nucleotide pools. Defects in AK1 are the cause of a form of hemolytic anemia. This gene is also upregulated in the brains of AD (Alzheimer′s disease) patients and downregulated in Duchenne muscular dystrophy. It is responsible for abnormal phosphorylation of tau via AMPK-GSK3β (AMP-activated protein kinase-glycogen synthase kinase-3β), thereby causing tau-mediated neurodegeneration.AK1 plays an important role in the regulation of cancer cell metabolism, metabolic signaling, as well as cell migration and invasion. It also aids in the progression of malignant transformation.
