We have cloned the mouse glucocorticoid receptor (GR) from both wild-type and glucocorticoid-resistant variants of the mouse lymphoma cell lines WEHI-7 and S49. Mapping of the mutations present in the variant receptors, together with deletion analysis of wild-type receptor, reveals that the receptor has three clearly defined domains. The COOH-termi...

Ser-Arg-rich (SR) proteins play numerous roles in spliceosome assembly and the regulation of splice-site selection. Whereas considerable attention has focused on the mechanistic details of SR protein activities, little is known concerning how these splicing regulators are controlled by the cell. Here we examined the subcellular localization of prec...

Cryptochromes use near-UV/blue light to regulate a variety of growth and adaptive process. Recent biochemical studies demonstrate that the Cryptochrome-Drosophila, Arabidopsis, Synechocystis, Human (Cry-DASH) subfamily of cryptochromes have photolyase activity exclusively for single-stranded cyclobutane pyrimidine dimer (CPD)-containing DNA substra...

The immunodominant T cell determinant of type II collagen (CII) recognized by DBA/1 mice (I-Aq) is CII 260-267. The aims of this study were to determine the role of the amino acid residues within CII 245-270 in T cell signal transduction. To that end, we utilized I-Aq-restricted, CII-specific T cell hybridomas and examined tyrosine phosphorylation ...

The C. elegans proteins MES-2 and MES-6, orthologs of the Polycomb group (PcG) chromatin repressors E(Z) and ESC, exist in a complex with their novel partner MES-3. The MES system participates in silencing the X chromosomes in the hermaphrodite germline. Loss of maternal MES function leads to germline degeneration and sterility. We report here that...

The structure of the chemically synthesized C-terminal region of the human agouti related protein (AGRP) was determined by 2D 1H NMR. Referred to as minimized agouti related protein, MARP is a 46 residue polypeptide containing 10 Cys residues involved in five disulfide bonds that retains the biological activity of full length AGRP. AGRP is a mammal...

Bovine neurotubulin has been labeled with dichlorotriazinyl-aminofluorescein (DTAF-tubulin) and microinjected into cultured mammalian cells strains PTK1 and BSC. The fibrous, fluorescence patterns that developed in the microinjected cells were almost indistinguishable from the pattern of microtubules seen in the same cells by indirect immunofluores...

Between 1 October 1986 and 31 March 1987, 55 cases of meningococcal disease were identified in the South-West of England, an attack rate of 1.54 per 100,000 during the study period. Antibiotics used in the treatment of the disease successfully eliminated nasopharyngeal carriage of meningococci in 13 out of 14 cases without use of rifampicin. The ov...

Methylation of histone H3K36 in higher eukaryotes is mediated by multiple methyltransferases. Set2-related H3K36 methyltransferases are targeted to genes by association with RNA Polymerase II and are involved in preventing aberrant transcription initiation within the body of genes. The targeting and roles of the NSD family of mammalian H3K36 methyl...
