Gene Information from Publications

Publication Link Summary of findings
16930991 Observational study of gene-disease association. (HuGE Navigator)
18006695 Observational study of gene-disease association. (HuGE Navigator)
17887956 human TopBP1 is involved in the formation of the initiation complex of replication in human cells and is required for the recruitment of Cdc45 to origins of DNA replication
17913746 Interaction between SPBP and TopBP1 was found to be mediated by the ePHD domain of SPBP and the BRCT6 domain of TopBP1.
17765870 Together, these results suggested that TopBP1 might be a mediator of DNA damage signaling from NBS1 to ATR and promote homologous recombination repair.
15961388 TopBP1 is a c-Abl-interacting protein and a repressor for c-Abl expression
12941802 hRad9/hHus1/hRad1 complex acts as a checkpoint sensor during S phase by rapidly localizing to sites of DNA damage and transducing checkpoint responses by facilitating proper localization of downstream checkpoint proteins, including TopBP1.
16984230 A study evaluating several chromatin modification domains encoded by TopBP1, and the implications of these findings are discussed in the context of the DNA damage response and the understanding of TopBP1 function is presented.
17448016 This report demonstrates aberrant expression of the TopBP1 protein in breast carcinoma. We propose TOPBP1 as a breast cancer susceptibility gene.
12773567 TopBP1 is regulated by PML by association and stabilization of the protein in response to IR-induced DNA damage
