Abstract:
The present invention relates to the discovery in mammalian cells, particularly human cells, of novel S-phase kinase associated proteins, p19 and p45, referred to herein as "Skp". As described herein, these proteins are components of the tumor cell-specific cyclin A/CDK2 complex and function to facilitate DNA replication. Interference with p45 function in vivo prevented entry into S-phase in both normal and transformed cells. Binding data indicated that p45 and p19 associate with each other in a binary complex. Moreover, p45 is required for p19 binding to cyclin A/CDK2.
Abstract:
Novel protein tyrosine phosphatases in which the invariant aspartate residue is replaced with an alanine residue and which bind to a tyrosine phosphorylated substrate and are catalytically attenuated are described. Also described are methods of identifying tyrosine phosphorylated proteins which complex with the described protein tyrosine phosphatases.
Abstract:
A method of regulating long term memory is disclosed. Also disclosed is isolated DNA encoding a cyclic 3',5'-adenosine monophosphate responsive transcriptional activator, isolated DNA encoding an antagonist of cyclic 3',5'-adenosine monophosphate-inducible transcription, isolated DNA encoding an enhancer-specific activator, and isolated DNA encoding a nitric oxide synthase.
Abstract:
Disclosed are methods for detecting mammalian genes encoding proteins which can function in microorganisms, particularly yeast, to modify, complement, or suppress a genetic defect associated with an identifiable phenotypic alteration or characteristic in the microorganism. Disclosed also are mammalian DNA sequences cloned by the above method, as well as polypeptide products of the expression of the DNA sequences in procaryotic or eucaryotic host cells and antibody substances which are specifically immunoreactive with said expression products. More specifically, the present invention relates to methods for cloning mammalian genes which encode products which modify, complement or suppress a genetic defect in a biochemical pathway in which cAMP participates or in a biochemical pathway which is controlled, directly or indirectly, by a RAS-related protein, to products (RNA, proteins) encoded by the mammalian genes cloned in this manner, and to antibodies which can bind the encoded proteins.
Abstract:
The present invention relates to a method for identifying or shielding functional sites or epitopes of proteins that enter the exocytotic pathway of eukaryotic cells (transportable proteins) by the addition of supernumerary N-linked oligosaccharide side chains at chosen sites on the surface thereof using oligonucleotide mutagenesis. The present invention also relates to mutant transportable proteins having supernumerary N-linked oligosaccharide side chains which shield functional sites or epitopes; and genes which encode the same.
Abstract:
A sensitive bioassay for transforming genes based on the tumorigenicity of cotransfected NIH3T3 cells in nude mice is disclosed. Genes mcf2 and mcf3 have been detected in tissue breast cancer using this assay.
Abstract:
Compounds of formula: are described herein. The compounds selectively complex copper and are therefore useful both abiotically for measuring and detecting small amounts of copper and, in biological systems, for treating diseases associated with inappropriate copper levels, such as Wilson's disease and gastric cancer.
Abstract:
A readrRNA (RNA sensing by Endogenous ADAR) molecule is a modular RNA molecule that facilitates sensing and detection of a cell type or cell status of a cell, including a cell of a mammalian nervous system, such as a neuronal or non-neuronal cell of the mammalian central and/or peripheral nervous system, and/or facilitates delivery of an effector protein to the selected cell. A composition that includes such a modular RNA molecule and another nucleic acid (linked or unlinked to the modular RNA molecule) is a CellREADR (Cell access through RNA sensing by Endogenous ADAR). CellREADR senses the presence of a selected cell RNA in a cell of a mammalian nervous system via readrRNA and leverages RNA editing mediated by ADAR (adenosine deaminase acting on RNA) for coupling the detection of a cell-defining RNA with translation of one or more effector proteins in a cell of a mammalian nervous system.
Abstract:
Monocot plants heterozygous for centromeric histone 3 (CenH3) and optionally expressing gene editing constructs, for use in inducing haploids of a monocot target plant and optionally pass-through gene editing are provided. The monocot haploid inducer plants are typically composed of diploid plant cells having only one allele encoding a functional CENH3 protein. The diploid plant cells can also include, for example, one CenH3 allele encoding non-functional CENH3 protein. In some embodiments, the allele encoding non-functional CENH3 protein is a frameshift mutation, protein null allele, an RNA null allele, or a combination thereof. The monocot haploid inducer plant can also include gene editing machinery, such as a site-directed nuclease and optionally a guide RNA stably expressed by cells of the monocot plant. Methods of inducing formation of a target haploid monocot plant while optionally simultaneously modifying the target monocot plant’s genome are also provided.
