Midler og fremgangsmåder til fremstilling af en protein gennem chromatinåbnere, som kan göre chromatin mere tilgængeligt for transkriptionsfaktorer

摘要

Described are means and methods for providing a cell with a protein expression unit, the method comprising providing a nucleic acid sequence comprising the unit with a nucleic acid sequence encoding a binding site for a member of a chromatin modification system for rendering chromatin more accessible for transcription (opener), wherein the opener is present in the cell. Preferred openers comprise histone modification proteins, chromatin remodeling proteins and trithorax group proteins or equivalents. The cells thus generated and nucleic acid sequences encoding such openers are provided. Openers are preferred in the context of STAR and TRAP sequences.
