GTP-binding domain: three consensus sequence elements with distinct spacing

Abstract: A sequence comparison of nine functionally different GTP-binding protein families has yielded further information on the general characterization of the conservation and importance of amino acid sequences in the GTP-binding domain, including a consensus sequence composed of three consensus elements GXXXXGK, DXXG, and NKXD with consensus spacings of either 40-80 or approximately equal to 130-170 amino acid residues between the first and second elements and approximately 40-80 amino acid residues between the second and third sequence elements; the sequence NKXW in place of NKXD in the sequence element responsible for base specificity allows the use of ITP as well as GTP; dGTP can be used with essentially the same efficiency as GTP; signal transducing proteins and enzymes have been identified in the nine families; and family conservations allow the identification of the most probable consensus sequence element when more than one is present. Employing these features we have screened the protein sequence data base of the Protein Identification Resource and have identified only known GTP-binding proteins with the exception of protein 2C from foot-and-mouth disease virus as matching the consensus sequence. Based on this finding we predict that foot-and-mouth disease virus protein 2C binds GTP and, by analogy, that protein 2C from several related viruses (polio, rhino, encephalomyocarditis, and cowpea mosaic) will bind a nucleotide as part of its biologic activity.

Modifier genes in mice and humans.

Abstract: An emerging theme of studies with spontaneous, engineered and induced mutant mice is that phenotypes often depend on genetic background, implying that genetic modifiers have a role in guiding the functional consequences of genetic variation. Understanding the molecular and cellular basis by which modifier genes exert their influence will provide insights into developmental and physiological pathways that are critical to fundamental biological processes, as well as into novel targets for therapeutic interventions in human diseases.

Emerging functional and mechanistic paradigms of mammalian long non-coding RNAs

Abstract: The recent discovery that the human and other mammalian genomes produce thousands of long non-coding RNAs (lncRNAs) raises many fascinating questions. These mRNA-like molecules, which lack significant protein-coding capacity, have been implicated in a wide range of biological functions through diverse and as yet poorly understood molecular mechanisms. Despite some recent insights into how lncRNAs function in such diverse cellular processes as regulation of gene expression and assembly of cellular structures, by and large, the key questions regarding lncRNA mechanisms remain to be answered. In this review, we discuss recent advances in understanding the biology of lncRNAs and propose avenues of investigation that may lead to fundamental new insights into their functions and mechanisms of action. Finally, as numerous lncRNAs are dysregulated in human diseases and disorders, we also discuss potential roles for these molecules in human health.

Scalable Fabrication of Nanoporous Carbon Fiber Films as Bifunctional Catalytic Electrodes for Flexible Zn-Air Batteries.

Abstract: A flexible nanoporous carbon-fiber film for wearable electronics is prepared by a facile and scalable method through pyrolysis of electrospun polyimide. It exhibits excellent bifunctional electrocatalytic activities for oxygen reduction and oxygen evolution. Flexible rechargeable zinc-air batteries based on the carbon-fiber film show high round-trip efficiency and mechanical stability.
