High impact information on Csrp2

  • In contrast to the actin-binding proteins SM22alpha and alpha-actinin, GFP-CRP2 did not translocate into the podosomes induced by this treatment, but remained preferentially bound to the stress fibres, suggesting an actin filament-stabilising role for CRP2 [1].
  • Using a green fluorescent protein (GFP)-tagged construct of CRP2 we analysed its localisation and dynamics in A7r5 rat smooth muscle cells [1].
  • CRP2 was associated with the actin cytoskeleton and decorated actin stress fibres in a continuous fashion, unlike the periodic labelling pattern observed for alpha-actinin and zyxin, which also accumulate in focal adhesions [1].
  • Finally, four genes, caveolin-1, two LIM proteins (enigma and SmLIM) and Id3a, were identified [2].
