One of the major determinants of organic solvent tolerance is the increase in membrane phospholipids. Here we report for the first time that an increase in the synthesis of phosphatidic acid is responsible for enhanced phospholipid synthesis that confers tolerance to the organic solvent in Saccharomyces cerevisiae. This increase in phosphatidic acid(More)
cgi-58 (comparative gene identification-58) is a member of alpha/beta-hydrolase family of proteins. Mutations in CGI-58 are shown to be responsible for a rare genetic disorder known as Chanarin-Dorfman syndrome, characterized by an excessive accumulation of triacylglycerol in several tissues and ichthyosis. We have earlier reported that YLR099c encoding(More)
Synaptogenesis is required for wiring neuronal circuits in the developing brain and continues to remodel adult networks. However, the molecules organizing synapse development and maintenance in vivo remain incompletely understood. We now demonstrate that the immunoglobulin adhesion molecule SynCAM 1 dynamically alters synapse number and plasticity.(More)
Tourette's syndrome is a common developmental neuropsychiatric disorder characterized by chronic motor and vocal tics. Despite a strong genetic contribution, inheritance is complex, and risk alleles have proven difficult to identify. Here, we describe an analysis of linkage in a two-generation pedigree leading to the identification of a rare functional(More)
Human CGI-58 (for comparative gene identification-58) and YLR099c, encoding Ict1p in Saccharomyces cerevisiae, have recently been identified as acyl-CoA-dependent lysophosphatidic acid acyltransferases. Sequence database searches for CGI-58 like proteins in Arabidopsis (Arabidopsis thaliana) revealed 24 proteins with At4g24160, a member of the(More)
We have previously characterized a protein, enhancer 1 binding factor (E1BF), from rat cells that can modulate RNA polymerase I-directed transcription of the rat rRNA gene in vitro. E1BF, a heterodimeric DNA binding protein composed of 72-kDa and 85-kDa subunits, is related to the human Ku autoantigen with respect to immunological and certain structural(More)
cDNA of human fibroblast growth factor 8 isoform b (FGF8b) was cloned for the first time into a plant expression vector with or without endoplasmic reticulum retention signal (KDEL) and was transiently expressed as His tagged fusion protein in Nicotiana tabacum leaves through Agrobacterium mediated gene transfer by vacuum infiltration method. Expression of(More)
Previous study has demonstrated that a far upstream 174-bp spacer sequence of the rat rRNA-encoding (rDNA) gene can function as an enhancer in vitro in an orientation- and distance-independent manner [Dixit et al., J. Biol. Chem. 262 (1987) 11616-11622]. To demonstrate that this element can also function in vivo, two rat rDNA-cat plasmids, one with the(More)
We have previously demonstrated that the core promoter of rat ribosomal RNA gene (rDNA) contains an E-box-like sequence to which the core promoter binding factor CPBF binds and that the 44 kDa subunit of this protein is immunologically related to USF1, the helix--loop--helix-zipper DNA binding protein. Further, we showed that RNA polymerase I (pol I)(More)
