Paf1, RNA polymerase II associated factor, homolog

Paf1, Pd2
This gene encodes a subunit of the polymerase associated factor (PAF1) complex. The PAF1 complex interacts with RNA polymerase II and plays a role in transcription elongation as well as histone modifications including ubiquitylation and methylation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2012] (from NCBI)

Formation and decay of P680 (P(D1)-P(D2))⁺PheoD1⁻ radical ion pair in photosystem II core complexes.
Shuvalov et al., Semënov, Russia. In Biochim Biophys Acta, 30 Sep 2014
The kinetics of the observed rise was ascribed to charge separation between Chl (chlorophyll a) dimer, primary electron donor in PSII (P680*) and Pheo located in D1 protein subunit (PheoD1) absorbing at 420 nm, 545 nm and 680 nm with formation of the ion-radical pair P680⁺PheoDI⁻.

New insights into the mechanism of the DNA/doxorubicin interaction.
García et al., Burgos, Spain. In J Phys Chem B, Mar 2014
A thermodynamic and kinetic study of the binding of doxorubicin to DNA, carried out by circular dichroism, viscometry, differential scanning calorimetry, fluorescence, isothermal titration calorimetry, and T-jump relaxation measurements, has enabled us to characterize for the first time two different types of calf thymus DNA (ctDNA)/DOX complexes: PD1 for C(DOX)/C(DNA) < 0.3, and PD2 for higher drug content.
Postoperative drainage with one chest tube is appropriate for pulmonary lobectomy: a randomized trial.

Pol II CTD kinases Bur1 and Kin28 promote Spt5 CTR-independent recruitment of Paf1 complex.
Hinnebusch et al., Bethesda, United States. In Embo J, 2012
These results identify an Spt5 phosphorylated C-terminal repeats-independent pathway of Paf1C recruitment requiring Kin28, Bur1, and the Spt5 phosphorylated C-terminal repeats-interaction domain of Cdc73.

Histone H3R17me2a mark recruits human RNA polymerase-associated factor 1 complex to activate transcription.
Xu et al., Madison, United States. In Proc Natl Acad Sci U S A, 2012
PAF1c acts as an arginine methyl histone effector that is recruited to promoters and activates a subset of genes, including targets of estrogen signaling.
Suppression of the antiviral response by an influenza histone mimic.
Tarakhovsky et al., New York City, United States. In Nature, 2012
We show that the NS1 protein of influenza A H3N2 subtype possesses a histone-like sequence (histone mimic) that is used by the virus to target the human PAF1 transcription elongation complex (hPAF1C).
Paf1 restricts Gcn4 occupancy and antisense transcription at the ARG1 promoter.
Arndt et al., Pittsburgh, United States. In Mol Cell Biol, 2012
By promoting histone H2B lysine 123 ubiquitylation, Paf1 represses the ARG1 gene by negatively affecting Gcn4 occupancy at the promoter.

Neurocardiology. Brain mechanisms underlying fatal cardiac arrhythmias.
Skinner, Houston, United States. In Neurol Clin, 1993
This may arise because the PD2 is sensitive to the net degrees of freedom of the heartbeat generator, which, under the influence of the nerves and the coronary circulation, can be shifted so the resulting dynamics cause the initiation of lethal arrhythmogenesis.
Application of chaos theory to biology and medicine.
Mitra et al., Houston, United States. In Integr Physiol Behav Sci, 1992
For biological systems, the point correlation dimension (PD2) has an advantage in that it does not presume stationarity of the data, as the D2 algorithm must, and thus can track the transient non-stationarities that occur when the systems changes state.
