This domain is widely distributed in all domains of life and occur in stand-alone form and as C-terminal fusions to pantothenate kinase (PanK) in plants and animals. They are metal-dependent phosphatases involved in metabolic damage-control processes termed "damage pre-emption" or "housecleaning". S.cerevisiae Damage-control phosphatase YMR027W and the human orthologue Damage-control phosphatase ARMT1 (also known as C6orf211) are involved in response to DNA damage, a damage pre-emption function. Crystal structure of Damage-control phosphatase At2g17340 from Arabidopsis revealed a novel protein fold and several conserved residues coordinating a metal ion (probably Mg2+), which exhibits a high degree of conservation, suggesting that the metal-binding site is central for the function [1].
