Journal ArticleDOI
Proliferating cell nuclear antigen (PCNA): a key factor in DNA replication and cell cycle regulation.
TL;DR: A phylogenetic comparison of PCNA genes suggests that the multi-functionality observed in most species is a product of evolution.
Journal ArticleDOI

TL;DR: An update on the identification and characterization of 126 rat mutants, which disrupt expression of genes of numerous categories, including chromatin structural and remodeling genes, and genes encoding proteins implicated in nuclear targeting, cell wall structure and metabolism, cytoskeleton structure and function, and signal transduction.
Journal ArticleDOI
Both the Escherichia coli chaperone systems, GroEL/GroES and DnaK/DnaJ/GrpE, can reactivate heat-treated RNA polymerase. Different mechanisms for the same activity.

TL;DR: It is shown that the GroEL (Hsp60 equivalent) chaperone protein can protected purified Escherichia coli RNA polymerase (RNAP) holoenzyme from heat inactivation better than the DnaK chaper one can.
Journal ArticleDOI
Import of Agrobacterium T-DNA into Plant Nuclei: Two Distinct Functions of VirD2 and VirE2 Proteins
TL;DR: It is proposed that VirD2 directs the T-DNA complex to the nuclear pore, whereas both proteins mediate its passage through the pore and by binding to ssDNA, VirE2 may shape the T -DNA complex such that it is accepted for translocation into the nucleus.
Journal ArticleDOI
Import of DNA into mammalian nuclei by proteins originating from a plant pathogenic bacterium
TL;DR: It is reported that the bacterium-derived and plant-adapted protein-DNA complex, made in vitro, can be efficiently imported into mammalian nuclei following the classical importin-dependent nuclear import pathway, demonstrating the potential of this approach to enhance gene transfer to animal cells.
