Mec1/Tel1 Phosphorylation of the INO80 Chromatin Remodeling Complex Influences DNA Damage Checkpoint Responses
The yeast Mec1/Tel1 kinases, ATM/ATR in mammals, coordinate the DNA damage response by phosphorylating proteins involved in DNA repair and checkpoint pathways. Recently, ATP-dependent chromatin remodeling complexes, such as the INO80 complex, have also been implicated in DNA damage responses, although regulatory mechanisms that direct their function remain unknown. Here, we show that the Ies4 s...
متن کاملAround the World of DNA Damage INO80 Days
DNA damage is detected and repaired in the context of chromatin. In this issue of Cell, van Attikum et al. (2004) and Morrison et al. (2004) demonstrate that double-stranded break repair involves the recruitment of a specialized chromatin remodeling complex, INO80, through an interaction with phosphorylated histone H2A.
متن کاملMechanism of DNA damage tolerance.
DNA damage may compromise genome integrity and lead to cell death. Cells have evolved a variety of processes to respond to DNA damage including damage repair and tolerance mechanisms, as well as damage checkpoints. The DNA damage tolerance (DDT) pathway promotes the bypass of single-stranded DNA lesions encountered by DNA polymerases during DNA replication. This prevents the stalling of DNA rep...
متن کاملO-35: Over-Expression of XRCC1 As Potential Biomarker for Poor Prognosis in Human Preimplantation Embryos: Selection by Study of 84 Genes Involved in DNA Damage Signaling Pathways
Background: Chromosome abnormalities are associated with poor morphology and development in human preimplantation embryos, all together lead to poor outcomes. This study aimed to explore altered expression of DNA damage pathways in “poor morphological and development embryos with sever aneuploidies”. Materials and Methods: Surplus day-4 embryos of PGD cases were pooled in two groups: Poor progn...
متن کاملPhosphorylation of human replication protein A by the DNA-dependent protein kinase is involved in the modulation of DNA replication.
The single-stranded DNA-binding protein, Replication Protein A (RPA), is a heterotrimeric complex with subunits of 70, 32 and 14 kDa involved in DNA metabolism. RPA may be a target for cellular regulation; the 32 kDa subunit (RPA32) is phosphorylated by several cellular kinases including the DNA-dependent protein kinase (DNA-PK). We have purified a mutant hRPA complex lacking amino acids 1-33 o...
