    [Abstract] The orientation of a DNA-binding protein bound on DNA is determinative in directing the assembly of other associated proteins in the complex for enzymatic action. As an example, in a replisome, the orientation of the DNA helicase at the replication fork directs the assembly of the other associated replisome proteins. We have recently determined ...
    Measuring Nucleosome Assembly Activity in vitro with the Nucleosome Assembly and Quantification (NAQ) Assay

    [Abstract] Nucleosomes organize the eukaryotic genome into chromatin. In cells, nucleosome assembly relies on the activity of histone chaperones, proteins with high binding affinity to histones. At least a subset of histone chaperones promotes histone deposition in vivo. However, it has been challenging to characterize this activity, due to the lack ...
    Determination of Adeno-associated Virus Rep DNA Binding Using Fluorescence Anisotropy
    [Abstract] Quantitative measurement of proteins binding to DNA is a requisite to fully characterize the structural determinants of complex formation necessary to understand the DNA transactions that regulate cellular processes. Here we describe a detailed protocol to measure binding affinity of the adeno-associated virus (AAV) Rep68 protein for the ...
