Previous work has established that heterogeneous nuclear ribonucleoprotein K (hnRNP K) is stabilized in an ATM-dependent manner in response to DNA damage and acts as a cofactor for p53-mediated transcription. Here, we show that in response to DNA damage caused by ionizing radiation, hnRNP K is phosphorylated in an ATM-dependent manner. Furthermore, our data indicate that ATM-dependent hnRNP K p...

Efficient task scheduling algorithm is critical for application programs to achieve high performance in heterogeneous computing systems. Although a large number of scheduling heuristics have been presented in the literature, most of them are mainly for the systems with homogeneous processors. In this paper, we present a novel task scheduling algorithm, heterogeneous task duplication scheduling ...

The rate of cell-cycle progression must be tuned in response to nutrient levels to ensure that sufficient materials are synthesized to generate viable daughters. We report that accumulation of the yeast M phase B-cyclin CLB2 mRNA depends on assembly and activation of the heterogeneous nuclear RNA-binding protein (hnRNP) arginine methyltransferase Hmt1, which is promoted by the kinase Dbf2 and c...

The C proteins (C1 and C2) are major constituents of the 40S subparticle of heterogeneous nuclear ribonucleoprotein complexes (hnRNPs) (Beyer, A.L., M.E. Christensen, B.W. Walker, and W.M. LeStourgeon, 1977, Cell, 11:127-138) and are two of the most prominent proteins that become cross-linked by ultraviolet light to heterogeneous nuclear RNA (hnRNA) in vivo. Studies are described here on the ch...
