Human RECQL5β stimulates flap endonuclease 1
Human RECQL5 is a member of the RecQ helicase family which is implicated in genome maintenance. Five human members of the family have been identified; three of them, BLM, WRN and RECQL4 are associated with elevated cancer risk. RECQL1 and RECQL5 have not been linked to any human disorder yet; cells devoid of RECQL1 and RECQL5 display increased chromosomal instability. Here, we report the physic...

متن کاملAntisense Proliferating Cell Nuclear Antigen Oligonucleotides
We have used antisense phosphorothioate oligonucleotides to define the role played by proliferating cell nuclear antigen (PCNA) in neointimal accumulation of smooth muscle cells in a rat carotid artery injury model. The short-term extraluminal delivery of 250 nmol of antisense oligonucleotides, but not control oligonucleotides, immediately after arterial injury produces a 77% suppression of PCN...
متن کاملOkazaki fragment processing: Modulation of the strand displacement activity of DNA polymerase by the concerted action of replication protein A, proliferating cell nuclear antigen, and flap endonuclease-1
DNA polymerase (pol) delta is essential for both leading and lagging strand DNA synthesis during chromosomal replication in eukaryotes. Pol delta has been implicated in the Okazaki fragment maturation process for the extension of the newly synthesized fragment and for the displacement of the RNA/DNA segment of the preexisting downstream fragment generating an intermediate flap structure that is...
متن کاملMammalian proliferating cell nuclear antigen stimulates the processivity of two wheat embryo DNA polymerases.
Multiple DNA polymerases have been described in all organisms studied to date. Their specific functions are not easy to determine, except when powerful genetic and/or biochemical tools are available. However, the processivity of a DNA polymerase could reflect the physiological role of the enzyme. In this study, analogies between plant and animal DNA polymerases have been investigated by analyzi...
