Adenylate kinases are involved in regulating the adenine nucleotide composition within a cell by catalyzing the;reversible transfer of phosphate groups among adenine nucleotides. Three isozymes of adenylate kinase, namely 1, 2,;and 3, have been identified in vertebrates; this gene encodes isozyme 2. Expression of these isozymes is;tissue-specific and developmentally regulated. Isozyme 2 is localized in the mitochondrial intermembrane space and may;play a role in apoptosis. Mutations in this gene are the cause of reticular dysgenesis. Alternate splicing results in;multiple transcript variants. Pseudogenes of this gene are found on chromosomes 1 and 2.
