Decreased expression of the USP44 deubiquitinase has been associated with global increases in H2Bub1 levels during mouse embryonic stem cell (mESC) differentiation. However, whether USP44 directly deubiquitinates histone H2B or how its activity is targeted to chromatin is not known. We identified USP44 as an integral subunit of the nuclear receptor(More)
Viral infection triggers innate immune signaling, which in turn induces interferon-β (IFN-β) production to establish innate antiviral immunity. Previous studies showed that Gcn5 (Kat2a), a histone acetyltransferase (HAT) with partial functional redundancy with PCAF (Kat2b), and Gcn5/PCAF-mediated histone H3K9 acetylation (H3K9ac) are enriched on the active(More)
To improve the technique of optimizing reversible logic circuit and reduce the cost of reversible logic circuit, the template technology is analyzed, finding that Maslov's templates are incomplete in that the control lines are incomplete. By introducing the library of template control lines concept, templates are reconstructed and named semi-template. The(More)
Histone H3 methylation on Lys4 (H3K4me) is associated with active gene transcription in all eukaryotes. In Saccharomyces cerevisiae, Set1 is the sole lysine methyltransferase required for mono-, di-, and trimethylation of this site. Although H3K4me3 is linked to gene expression, whether H3K4 methylation regulates other cellular processes, such as mitosis,(More)

A finite element method was developed to simulate the convective coefficient of cooling water pipe in concrete, and the mean Nusselt numbers on each section in the cooling water pipe were obtained. Numerical results show that the flow field distribution was very complex with a secondary flow appeared in the bend position. The cooling water flow velocity(More)
Histone H2B monoubiquitination (H2Bub1) is centrally involved in gene regulation. The deubiquitination module (DUBm) of the SAGA complex is a major regulator of global H2Bub1 levels, and components of this DUBm are linked to both neurodegenerative diseases and cancer. Unexpectedly, we find that ablation of USP22, the enzymatic center of the DUBm, leads to a(More)
