1 Olivera, Baldomero M.Conus peptides: phylogenetic range of biological activityThe major function of the venoms of the predatory marine snails belonging to the genus Conus is to paralyze prey. Thus, the venom of each Conus species acts on receptors and ion channels of the prey; previous studies suggested much less activity on homologous receptor targets in more distant taxa....Conus peptides; Conopeptides; Conotoxins1992
2 Capecchi, Mario R.Creating mice with targeted disruptions in protooncogenes and homeobox genes, NIH Director's Lecture given May 21, 1992This is an audio transcript of a 1 hour, 2 minutes and 12 seconds lecture given at the National Institutes of Health by Mario Capecchi on 1992/05/21. Beginning with a short summary of the mechanics of gene transfer and the ability to create germline chimera with mutations that become hereditary wit...Transgenic mice; Gene targeting; Genetic engineering; Molecular genetics; Mutagenesis; Homeobox genes; Histology - Pathological; Gene expression; Gene regulation; Genotype; Phenotype1992
3 Davidson, Diane W.Experimental manipulation of food bodies in CecropiaNeotropical Cecropia trees range from Mexico to Argentina and are typical of disturbed habitats. Cecropia plants provide food and housing for the ants in return for known or presumed protection from herbivores and vine cover. Glycogen-rich Mullerian bodies (MB's) are the predominant food source for ...Mullerian bodies; Trichilia; Cecropia tessmannii; Cecropia pungara1992
4 Olivera, Baldomero M.; Hillyard, David R.Heterodimeric structure of the spider toxin ω-Agatoxin IA revealed by precursor analysis and mass spectrometryWe report the first molecular characterization of a precursor sequence for a small, Ca2+ channel blocking, peptide spider toxin, ω-agatoxin IA. By integrating information generated from a molecular genetic approach using agatoxin cDNAs with data provided from mass spectrometry of the mature tox...Spider toxin w-Aga-IA; Heterodimeric structure1992
5 Adler, Frederick R.Information collection and spread by networks of patrolling antsTo study how a social group, such as an ant colony, monitors events occurring throughout its territory, we present a model of a network of patrolling ants engaged in information collection and dissemination. In this network, individuals follow independent paths through a region and can exchange sign...Patrolling network; ant colony; information-gathering1992
6 Beckerle, Mary C.Interaction between zyxin and α-actininZyxin is an 82-kD protein first identified as a component of adhesion plaques and the termini of stress fibers near where they associate with the cytoplasmic face of the adhesive membrane. We report here that zyxin interacts with the actin cross-linking protein α-actinin.Zyxin; Actinin; Actin1992
7 Ehleringer, James R.Plant adaptation in the Great Basin and Colorado PlateauAdaptive features of plants of the Great Basin are reviewed. The combination of cold winters and an arid to semiarid precipitation regime results in the distinguishing features of the vegetation in the Great Basin and Colorado Plateau. The primary effects of these climatic features arise from how t...Plant adaptation; Great Basin; Colorado Plateau; Cold deserts1992
8 Beckerle, Mary C.Purification and characterization of zyxin, an 82,000-Dalton component of adherens junctionsWe describe here the purification and characterization of a recently identified adherens junction protein that has an apparent molecular mass of 82 kDa on sodium dodecyl sulfate-polyacrylamide gels (Beckerle, M. C. (1986) J. Cell Biol. 103, 1679-1687). The 82-kDa protein was isolated from avian smoo...Zyxin1992
9 Ehleringer, James R.; Negus, Norman C.Red Butte Canyon Research Natural Area: history, flora, geology, climate, and ecologyRed Butte Canyon is a protected, near pristine canyon entering Salt Lake Valley, Utah. It contains a well-developed riparian zone and a perennial stream; hillside vegetation ranges from grasslands on the lower limits to Douglas-fir and aspen stands at the upper elevations. In this paper we describe ...Intermountain West; Grassland; Oak-maple; Plant adaptation; Red Butte Canyon Research Natural Area; Human impact1992
10 Beckerle, Mary C.Zyxin and cCRP: Two interactive LIM domain proteins associated with the cytoskeletonInteraction with extracellular matrix can trigger a variety of responses by cells including changes in specific gene expression and cell differentiation. The mechanism by which cell surface events are coupled to the transcriptional machinery is not understood, however, proteins localized at sites o...Zyxin; Cysteine-rich proteins; cCRP; LIM domain1992
