  • putative gene regulator for cellular mechanisms mediating neuronal excitability and survival
  • control of sensitivity to cockayne enhanced by delta FosB through changes in CDK5 level
  • implicated in the regulation of genes important for inflammation, proliferation, and differentiation and have been shown to be involved in wound healing (Neub 2007)

  • cockayne
  • protein
  • CDK5
  • is the mediator of SERPINB2 transactivator function explaining the orientation dependence observed for SERPINB2 transactivator activity
  • FOSB and JUN can derepress transcription from the SERPINB2 promoter which may have general significance for SERPINB2-expressing cells
