A series of V- and Y-shaped nucleic acids, related to the splicing intermediates derived from S. cerevisiae actin pre-mRNA, were prepared. The effects of such branched nucleic acids (bNAs) on the efficiency of in vitro pre-mRNA splicing in yeast were

Little is known about the regions of RNA polymerase II (RNAPII) that are involved in the process of transcript elongation and interaction with elongation factors. One elongation factor, TFIIS, stimulates transcript elongation by binding to RNAPII and

The human p68 kinase is an interferon-regulated enzyme that inhibits protein synthesis when activated by double-stranded RNA. We show here that when expressed in Saccharomyces cerevisiae, the p68 kinase produced a growth suppressing phenotype resulti

A 2.3-kilobase pair DNA fragment of the yeast CAL1 gene was cloned by complementation of the cal1-1 mutation, which causes a defect in nuclear division and bud formation (Ohya, Y., Ohsumi, Y., and Anraku, Y. (1984) Mol. & Gen. Genet. 193, 389-394). N

RNA polymerase II (RNAPII) is a complex multisubunit enzyme responsible for the synthesis of pre-mRNA in eucaryotes. The enzyme is made of two large subunits associated with at least eight smaller polypeptides, some of which are common to all three R

Certain mutations in gyrA and gyrB, the genes encoding the two subunits of DNA gyrase, are known to influence expression of the his operon (K. E. Rudd and R. Menzel, Proc. Natl. Acad. Sci. USA 84:517-521, 1987). Such mutations lead to a decrease in t

Protein purification efforts for structural genomics will focus on automation for the readily-expressed proteins, and process development for the more difficult ones, such as membrane proteins. Thousands of proteins are expected to be produced in the

A binding site for the transcription factor Abf1p was identified as an important promoter element of the gene that encodes Rpo26, a subunit common to all three yeast nuclear RNA polymerases (RNAP). Mutations in the Abf1p binding site were identified

Base-pairing between U2 and U6 snRNAs to form intermolecular helix II has been demonstrated previously as a requirement for pre-mRNA splicing in mammalian cells. In contrast, deletion and substitution mutation experiments in yeast have indicated that

Several distinct domains of U4 small nuclear (sn)RNA interact with other components of the spliceosome and are essential for pre-mRNA splicing. We have previously shown that single point mutations (Hu et al., 1995) in the central domain of the yeast
