Mutations in stem-loop IIa of yeast U2 RNA cause cold-sensitive growth and cold-sensitive U2 small nuclear ribonucleoprotein function in vitro. Cold-sensitive U2 small nuclear RNA adopts an alternative conformation that occludes the loop and disrupts the stem but does so at both restrictive and permissive temperatures. To determine whether alternative U2(More)
U2 small nuclear RNA is a highly conserved component of the eukaryotic cell nucleus involved in splicing messenger RNA precursors. In the yeast Saccharomyces cerevisiae, U2 RNA interacts with the intron by RNA-RNA pairing between the conserved branchpoint sequence UACUAAC and conserved nucleotides near the 5' end of U2 (ref. 4). Metazoan U2 RNA is less than(More)
—In this paper, we present a novel QoS (quality of service) multicast routing protocol (QMRP) for partially mobile wireless TDMA (time division multiple access) networks. This protocol has been inspired by the typical requirements of industrial networked control systems, i.e., systems exhibiting real-time behavior and therefore requiring predictable(More)
