The transcription cycle of RNA polymerase II in living cells
RNA polymerase II transcribes most eukaryotic genes. Its catalytic subunit was tagged with green fluorescent protein and expressed in Chinese hamster cells bearing a mutation in the same subunit; it complemented the defect and so was functional. Photobleaching revealed two kinetic fractions of polymerase in living nuclei: approximately 75% moved rapidly, but approximately 25% was transiently im...
متن کاملThe RNA polymerase II transcription cycle: cycling through chromatin.
The cycle of events that characterizes RNA polymerase II transcription has been the focus of intense study over the past two decades. Our knowledge of the molecular processes leading to transcriptional initiation is greatly improved, and the focus of many recent studies has shifted towards the less well-characterized events taking place after assembly of the pre-initiation complex, such as prom...
متن کاملArchaeology of RNA polymerase: factor swapping during the transcription cycle.
All RNAPs (RNA polymerases) repeatedly make use of their DNA template by progressing through the transcription cycle multiple times. During transcription initiation and elongation, distinct sets of transcription factors associate with multisubunit RNAPs and modulate their nucleic-acid-binding and catalytic properties. Between the initiation and elongation phases of the cycle, the factors have t...
متن کاملThe RNA polymerase II CTD coordinates transcription and RNA processing.
The C-terminal domain (CTD) of the RNA polymerase II largest subunit consists of multiple heptad repeats (consensus Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7), varying in number from 26 in yeast to 52 in vertebrates. The CTD functions to help couple transcription and processing of the nascent RNA and also plays roles in transcription elongation and termination. The CTD is subject to extensive post-tra...
متن کاملCell cycle regulation and RNA polymerase II.
The cell cycle and transcription by RNA polymerase II (RNAP II) are closely related. They utilize shared components. RNAP II transcriptional activity is modulated during the cell cycle. Cell cycle dependent changes in the phosphorylation status of the carboxyl-terminal domain (CTD) of the largest subunit of RNAP II (RNAP II-LS) alter transcription. Several CTD kinases are members of the cyclin-...
