Helicase II (Nuclear DNA helicase II/RNA helicase A)

Page updates 8/12/02

The presence of actin within the interface nucleus has been a hotly contentious issue. The debate has now swung heavily in favour of there being a physiologically relevant and important role for actin in the nucleus since the discovery of b-actin as a member of the BAF (Brg- or Brm-associated factors) complex (Shen et al, 2000). Nuclear DNA helicase II has now been found to bind F-actin (Zhang et al, 2002), possibly through the C-terminus region.
