Davis, Bryan J., Havener, Jody M., Ramsden, Dale A.
DNA polymerase μ is a member of the mammalian pol X family and reduces deletion during chromosome break repair by nonhomologous end joining (NHEJ). This biological role is linked to pol μ's ability...
Bukowy, Zuzanna, Harrigan, Jeanine A., Ramsden, Dale A., Tudek, Barbara, Bohr, Vilhelm A., Stevnsner, Tinna
Werner syndrome (WS) is a premature aging disorder caused by mutations in the WS gene (WRN). Although WRN has been suggested to play an important role in DNA metabolic pathways, such as...
Povirk, Lawrence F., Zhou, Rui-Zhe, Ramsden, Dale A., Lees-Miller, Susan P., Valerie, Kristoffer
Previous work suggested that phosphorylation of DNA-PKcs at several serine/threonine (S/T) residues at positions 2609–2647 promotes DNA-PK-dependent end joining. In an attempt to clarify the role...
Genomic instability due to V(D)J recombination-associated transposition (2006)
Reddy, Yeturu V.R., Perkins, Eric J., Ramsden, Dale A.
The first step in assembling immunoglobulin and T-cell receptors by V(D)J recombination has similarities to transposon excision. The excised transposon-like element then integrates into DNA targets...
Histone 3 lysine 4 methylation during the pre-B to immature B-cell transition (2004)
Perkins, Eric J., Kee, Barbara L., Ramsden, Dale A.
The relationship between chromatin modification and lymphocyte development is still poorly understood. Here we show a correlation between methylation of lysine 4 on histone 3 (H3‐K4) and...
Karmakar, Parimal, Snowden, Carey M., Ramsden, Dale A., Bohr, Vilhelm A.
The human Werner syndrome protein, WRN, is a member of the RecQ helicase family and contains 3′→5′ helicase and 3′→5′ exonuclease activities. Recently, we showed that the exonuclease...
Sensing of intermediates in V(D)J recombination by ATM (2002)
Perkins, Eric J., Nair, Ayyappan, Cowley, Dale O., Van Dyke, Terry, Chang, Yung, Ramsden, Dale A.
Conservation of sequence in recombination signal sequence spacers (1994)
Ramsden, Dale A., Baetz, Kristin, Wu, Gillian E.
The variable domains of immunoglobulins and T cell receptors are assembled through the somatic, site specific recombination of multiple germline segments (V, D, and J segments) or V(D)J...
Ku Recruits the XRCC4-Ligase IV Complex to DNA Ends
Nick McElhinny, Stephanie A., Snowden, Carey M., McCarville, Joseph, Ramsden, Dale A.
Genetic experiments have determined that Ku, XRCC4, and ligase IV are required for repair of double-strand breaks by the end-joining pathway. The last two factors form a tight complex in cells....

Mahajan, Kiran N., Nick McElhinny, Stephanie A., Mitchell, Beverly S., Ramsden, Dale A.
Mammalian DNA polymerase μ (pol μ) is related to terminal deoxynucleotidyl transferase, but its biological role is not yet clear. We show here that after exposure of cells to ionizing radiation...
Polymerase Mu Is a DNA-Directed DNA/RNA Polymerase
Nick McElhinny, Stephanie A., Ramsden, Dale A.
DNA polymerases are defined as such because they use deoxynucleotides instead of ribonucleotides with high specificity. We show here that polymerase mu (pol μ), implicated in the nonhomologous...
Ding, Qi, Reddy, Yeturu V. R., Wang, Wei, Woods, Timothy, Douglas, Pauline, Ramsden, Dale A., ...
The DNA-dependent protein kinase (DNA-PK) plays an essential role in nonhomologous DNA end joining (NHEJ) by initially recognizing and binding to DNA breaks. We have shown that in vitro, purified...
Histone 3 lysine 4 methylation during the pre-B to immature B-cell transition
Perkins, Eric J., Kee, Barbara L., Ramsden, Dale A.
The relationship between chromatin modification and lymphocyte development is still poorly understood. Here we show a correlation between methylation of lysine 4 on histone 3 (H3-K4) and activation...
Sensing of intermediates in V(D)J recombination by ATM
Perkins, Eric J., Nair, Ayyappan, Cowley, Dale O., Van Dyke, Terry, Chang, Yung, Ramsden, Dale A.
Ataxia-telangiectasia mutated (ATM) is required for resistance to radiation-induced DNA breaks. Here we use chromatin immunoprecipitation to show that ATM also localizes to breaks associated with...
