Molekularbiologische Untersuchung intrazellulärer Signalwege, die in T-Lymphozyten zur Aktivierung des Transkriptionsfaktors NF-ATc führen
Der Transkriptionsfaktor NF-ATc (Nuclear Factor of Activated T cells) kontrolliert die Genexpression in T-Lymphozyten. In dieser Arbeit, in der Jurkat-T-Zellen und embryonale 293-Zellen als Modellsysteme verwendet wurden, konnte gezeigt werden, daß die N-terminale transaktivierende Domäne TAD-A von …
