DNA damage signaling and repair in Dictyostelium discoideum.
Repair of DNA double strand breaks (DSBs) is critical for the maintenance of genome integrity. DNA DSBs can be repaired by either homologous recombination (HR) or nonhomologous end-joining (NHEJ). Whilst HR requires sequences homologous to the damaged DNA template in order to facilitate repair, NHEJ occurs through recognition of DNA DSBs by a variety of proteins that process and rejoin DNA termini by direct ligation. Here we review two recent reports that NHEJ is conserved in the social amoeb...Expand abstract
