Research Abstract |
RNA polymerase II (RNAPII) molecule is responsible for transcription that is a central cellular process. To reveal the principles of transcription, we have derived a mathematical model for RNAPII from the high-resolution molecular biological data. Cellular automaton simulations show that the cooperative motions of RNAPII molecules that represented by the injection timing of TSS, the barriers of the roadblocks due to the chromatin modifications that represented by the velocity gap, and the chromatin loop positions represented by the jump probabilities of RNAPII affect the dynamical and thermo-dynamical properties of transcription factory.
