Editor’s summary
These are exciting times for biology. The changes genomics brings to the way research is done in biological laboratories promise to be as profound as those triggered by the advent of recombinant DNA technology in the 1970s. It is in recognition of these changes that GenomeBiology is named and launched.

The Grail problem
Gregory A Petsko Genome Biology 2000, 1:comment002-comment002.2 (9 June 2000)
Full text | PDF | PubMed | Cited on BioMed Central
|
Editor’s summary
The Holy Grail is a familiar metaphor in science. A current Holy Grail is the complete sequence of the human genome, but there seems to be one for every field of biology.

Whither genomics?
Andrew W Murray Genome Biology 2000, 1:comment003-comment003.6 (9 June 2000)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
The flood of data from genome-wide analysis is transforming biology. We need to develop new, interdisciplinary approaches to convert these data into information about the components and structures of individual biological pathways and to use the resulting information to yield knowledge about general principles that explain the functions and evolution of life.

An overview of the structures of protein-DNA complexes
Nicholas M Luscombe, Susan E Austin, Helen M Berman, Janet M Thornton Genome Biology 2000, 1:reviews001-reviews001.37 (9 June 2000)
Abstract | Full text | PDF | PubMed | Cited on BioMed Central
|
Editor’s summary
On the basis of a structural analysis of 240 protein-DNA complexes contained in the Protein Data Bank (PDB), we have classified the DNA-binding proteins involved into eight different structural/functional groups, which are further classified into 54 structural families. Here we present this classification and review the functions, structures and binding interactions of these protein-DNA complexes.

Molecular mechanisms of spindle function
Claire E Walczak Genome Biology 2000, 1:reviews101-reviews101.4 (27 April 2000)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
The key molecules involved in regulating the assembly and function of the mitotic spindle are shared by evolutionarily divergent species. Studies in different model systems are leading to convergent conclusions about the central role of microtubule nucleation and dynamics and of kinesin-related motor proteins in spindle function.

What initiates actin polymerization?
Anne Ridley Genome Biology 2000, 1:reviews102-reviews102.4 (27 April 2000)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
For those working on the actin cytoskeleton, a major theme of the 39th annual meeting of the American Society for Cell Biology [http://www.faseb.org/ascb/meetings/am99/main99mtg.htm] (Washington DC, December 11-15, 1999) was the elucidation of how actin polymerization is initiated. The emphasis was on the regulation and localization of the Arp2/3 complex, which over the last two years has been shown to stimulate actin nucleation, and on the identification of additional proteins that interact with actin and Arp2/3 in a variety of organisms.

Editor’s summary
The availability of complete genomic sequences of Saccharomyces cerevisiae has catalyzed a cultural change in the practice of yeast biology, providing opportunities to develop high throughput techniques to define protein function, to define drug targets, and to discover and characterize drugs.

Membrane traffic between genomes
John Armstrong Genome Biology 2000, 1:reviews104-reviews104.4 (9 June 2000)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
Proteins of the Rab and SNARE families target vesicles to their intracellular destinations. A comparison of these families from the budding yeast, fission yeast, nematode and fruitfly genomes has implications for the organization of membrane traffic in different organisms.

The many hues of plant heterochromatin
Jeffrey L Bennetzen Genome Biology 2000, 1:reviews107-reviews107.4 (9 June 2000)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
Recent sequence and cytogenetic analyses of heterochromatin in Arabidopsis, together with other results from Arabidopsis and maize, indicate that plant heterochromatin can have very different origins, compositions and dynamics. Shared features that must determine and/or be a result of its unique biological properties are also revealed.

Chaotic actin
Dennis Bray Genome Biology 2000, 1:reviews108-reviews108.3 (9 June 2000)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
Living cells organize their internal contents by coordinating the chaotic thermal motion of protein molecules. A recent study, combining experiment with stochastic simulation, shows how this might be achieved in the case of actin polymerization.

Are plant formins integral membrane proteins?
Fatima Cvrcková Genome Biology 2000, 1:research001-research001.7 (27 April 2000)
Abstract | Full text | PDF | PubMed | Cited on BioMed Central
|
Editor’s summary
Formins are implicated in cellular morphogenesis and in communication between the actin cytoskeleton and the cell surface. Eight putative formin-coding genes have been found in the Arabidopsis genome sequence. Some lack parts of the conserved formin-homology 2 (FH2) domain and most have signal sequences and putative transmembrane segments that are not found in yeast or animals formins, placing plant formins in a distinct subfamily

Phylogenetic variation and polymorphism at the Toll-like receptor 4 locus (TLR4)
Irina Smirnova, Alexander Poltorak, Edward KL Chan, Colleen McBride, Bruce Beutler Genome Biology 2000, 1:research002-research002.10 (27 April 2000)
Abstract | Full text | PDF | PubMed | Cited on BioMed Central
|
Editor’s summary
The Toll-like receptor 4 gene (Tlr4) is thought to bind lipopolysaccharide and mediate lipopolysaccharide signal transduction in immune system cells. The Tlr4 genes of humans and mice have been sequenced, as well as the coding region and splice junctions of Tlr4 from 35 mouse strains, the chimpanzee and the baboon, revealing highly variable domains that may reflect differences in evolutionary selection and may underlie the magnitude of the response to lipopolysaccharide within a species.
