Adenosine 5’-triphosphate (ATP) là hợp chất cao năng quan trọng nhất, giữ vai trò cung cấp năng lƣợng trong mọi tế bào sống. Bởi vì trong phân tử ATP có hai liên kết phosphate cao năng, năng lƣợng tự do sẽ đƣợc giải phóng khi ATP bị thủy phân thành Adenosine 5’-diphosphate (ADP) và một phosphate vô cơ (Pi), hoặc Adenosine monophosphate (AMP) và pyrophosphate (PPi). Do đó, phần lớn các hoạt động sống nhƣ vận chuyển, hấp thu dinh dƣỡng, sinh tổng hợp các chất, phân chia tế bào … đều sử dụng ATP nhƣ nguồn năng lƣợng trực...

Wehave identifiedanovelmammaliangene, termednicolin1 gene (NICN1), that is present in human, dog and mouse, whereas it is absent from the available genome sequences of nonmammalian organisms. TheNICN1gene consists of six exons and spans about 6 kb of genomic DNA. It encodes a 213 amino acid protein that does not belong to any known protein family. Experiments using green fluorescent protein (GFP)-taggednicolin1 fusionproteins indicate that nicolin1 is a nuclear protein.

The ultimate step in Alzheimer’s disease Abgeneration involves c-secretase, which releases Abfrom its membrane-bound precursor. Asimilar presenilin-dependent proteolytic activity is implicated in the release of theNotch intracellular domain. We have developed a novel assay forc-secretase activity based on green fluorescent protein detection. This involves cotransfection of a substrate-activator based on the amyloid precursor protein or the Notch sequence and a fluorescent reporter gene.

Oxysterol binding protein (OSBP) and its homologs have been shown to regulate lipid metabolism and vesicular transport. However, the exact molecular function of individual OSBP homologs remains uncharacterized. Here we demonstrate that the yeast OSBP homolog, Osh6p, bound phos-phatidic acid and phosphoinositides via its N-terminal half containing the conserved OSBP-related domain (ORD). Using a green fluorescent protein fusion chimera, Osh6p was found to localize to the cytosol and patch-like or punctate structures in the vicinity of the plasma membrane....

Salt-inducible kinase-1 (SIK1) is phosphorylated at Ser577 by protein kinase A in adrenocorticotropic hormone-sti-mulated Y1 cells, and the phospho-SIK1 translocates from the nucleus to the cytoplasm. The phospho-SIK1 is dephosphorylated in the cytoplasmand re-enters thenucleus several hours later. By using green-fluorescent protein-tag-ged SIK1 fragments, we found that a peptide region (586– 612) was responsible for the nuclear localization of SIK1. Theregionwas namedthe
RK-rich region because of its Arg- and Lys-rich nature. ...

Phosphorylationof the transit peptideof several chloroplast-targeted proteins enables the binding of 14-3-3 proteins. The complex that forms, together with Hsp70, has been demonstrated to be an intermediate in the chloroplast pro-tein import pathwayin vitro[May, T. &Soll, J. (2000)Plant Cell12, 53–63]. In this paper we report that mutagenesis (in order to remove the phosphorylation site) of the transit peptide of the small subunit of ribulose bisphosphate carb-oxylase/oxygenase did not affect its ability to target green fluorescent protein to chloroplastsin vivo....

Pigments homologous to the green fluorescent protein (GFP) contribute up to 14% of the soluble protein content of many anthozoans. Maintenance of such high tissue levels poses a severe energetic penalty to the animals if protein turnover is fast. To address this as yet unexplored issue, we estab-lished that the irreversible green-to-red conversion of the GFP-like pig-

For a variety of coral species, we have studied the molecular origin of their coloration to assess the contributions of host and symbiont pigments. For the corals Catalaphyllia jardineiand an orange-emitting color morph of Lobophyllia hemprichii, the pigments belong to a particular class of green fluorescent protein-like proteins that change their color from green to red upon irradiation with400 nm light.

Fluorescence recovery after photobleaching (FRAP) and related techniques using green fluorescent protein (GFP)-tagged proteins are widely used to study the subcellular trafficking of proteins. It was concluded from these experiments that the cytokine-induced nuclear import of tyrosine-phos-phorylated (activated) signal transducer and activator of transcription 1 (STAT1) was rapid, while the constitutive shuttling of unphosphorylated STAT1 was determined to be inefficient.

TRPM4b is a Ca 2+ -activated, voltage-dependent monovalent cation chan-nel that has been shown to act as a negative regulator of Ca 2+ entry and to be involved in the generation of oscillations of Ca 2+ influx in Jurkat T-lymphocytes. Transient overexpression of TRPM4b as an enhanced green fluorescence fusion protein in human embryonic kidney (HEK) cells resulted in its localization in the plasma membrane, as demonstrated by confocal fluorescence microscopy.

Plastid envelope DNA-binding protein (PEND) is a DNA-binding protein with a chloroplast basic region-zipper domain at its N-terminus and a transmembrane domain at its C-terminus. The localization of PEND to the inner envelope membrane was demonstrated in a targeting experiment using isolated membranes and green fluorescent protein-tagged fusion pro-teins.

Minor structural proteins of mouse polyomavirus (MPyV) are essential for virus infection. To study their properties and possible contributions to cell death induction, fusion variants of these proteins, created by linking enhanced green fluorescent protein (EGFP) to their C- or N-termini, were prepared and tested in the absence of other MPyV gene products, namely the tumor antigens and the major capsid protein, VP1.

TheOryza sativalectin, abbreviated Orysata, is a mannose-specific, jacalin-related lectin expressed in rice plants after exposure to certain stress condi-tions. Expression of a fusion construct containing the rice lectin sequence linked to enhanced green fluorescent protein in Bright Yellow 2 tobacco cells revealed that Orysata is located in the nucleus and the cytoplasm of the plant cell, indicating that it belongs to the class of nucleocytoplasmic jacalin-related lectins.
