Function
"Required for checkpoint mediated cell cycle arrest in response to DNA damage within both the S phase and G2/M phases of the cell cycle. May serve as a scaffold for the recruitment of DNA repair and signal transduction proteins to discrete foci of DNA damage marked by 'Ser-139' phosphorylation of histone H2AFX. Also required for downstream events subsequent to the recruitment of these proteins. These include phosphorylation and activation of the ATM, CHEK1 and CHEK2 kinases, and stabilization of TP53 and apoptosis. ATM and CHEK2 may also be activated independently by a parallel pathway mediated by TP53BP1"
Mutation
"58 58 R->A: Abrogates binding to the MRE11 complex and to CHEK2 72 72 S->A: Abrogates binding to CHEK2 96 96 N->A: Abrogates binding to CHEK2 when associated with A-97 and A-98 97 97 G->A: Abrogates binding to CHEK2 when associated with A-96 and A-98 98 98 T->A: Abrogates binding to CHEK2 when associated with A-96 and A-97 1840 1840 K->R: Suppresses RNF4-mediated ubiquitination, accumulates at sites of DNA damage, defective homologous recombination"
