Description
This gene encodes an endo/exonuclease with 5′-3′ exonuclease activity. The encoded enzyme catalyzes the hydrolysis of ester linkages at the 5′ end of a nucleic acid chain. This enzyme is localized to the mitochondria and may play a role in programmed cell death. Alternatively spliced transcript variants have been described. A pseudogene exists on chromosome 18.
