To maintain genome DNA, DNA repair machinery has been developed in cellular life cycle. Multiple DNA repair pathways such as base excision repair, nucleotide excision repair, DNA cross link damage repair, DNA single strand break repair and DNA double strand break repair including nonhomologous end joining and homologous recombination are regulated by protein signal cascade. Because of limited gene number, protein posttranslational modification signal has advantage to control cell dynamics during development and senescence. This chapter focuses on how DNA repair proteins molecular modification including phosphorylation and ubiquitination contribute to genome stability pathway during mammalian development and disease.
