Transport and binding of molecules to specific sites are necessary for the assembly and function of ordered supramolecular structures in cells. For analyzing these processes in vivo, we have developed a confocal fluorescence fluctuation microscope that allows both imaging of the spatial distribution of fluorescent molecules with confocal laser scanning microscopy and probing their mobility at s...
Green fluorescent protein (GFP) is used extensively as a reporter protein to monitor cellular processes, including intracellular protein trafficking and secretion. In general, this approach depends on GFP acting as a passive reporter protein. However, it was recently noted that GFP oligomerizes in the secretory pathway of endocrine cells. To characterize this oligomerization and its potential r...
We used a 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP)-enhanced green fluorescent protein (EGFP) transgenic mouse to study postnatal subventricular zone (SVZ) progenitor fate, with a focus on the olfactory bulb (OB). The postnatal OB of the CNP-EGFP mouse contained EGFP+ interneurons and oligodendrocytes. In the anterior SVZ, the majority of EGFP+ progenitors were NG2+. These NG2+/EGFP+ p...
Arg96 is a highly conservative residue known to catalyze spontaneous green fluorescent protein (GFP) chromophore biosynthesis. To understand a role of Arg96 in conformational stability and structural behavior of EGFP, the properties of a series of the EGFP mutants bearing substitutions at this position were studied using circular dichroism, steady state fluorescence spectroscopy, fluorescence l...
A Na(+)/H(+) antiporter gene (CvNHA1) was cloned from the salt-tolerant yeast Candida versatilis. CvNHA1 encodes an antiporter with a typical yeast plasma membrane Na(+)/H(+) antiporter structure. Transcription of CvNHA1 in C. versatilis cells was dependent on the salinity of the culture. When CvNHA1 was expressed in salt-sensitive Saccharomyces cerevisiae cells, increased salt-tolerance was ob...
The Drosophila gene cacophony (cac) encodes the 1 subunit of a presynaptic voltage-gated calcium channel. This gene locus was first identified, and named, because of a role in the male courtship song. These channels, activated during an action potential, trigger neurotransmitter release at the fly neuromuscular junction. To visualize their location in live animals, Kawasaki et al. created a tra...
The motor neuron-like cell line NSC-34 has become a widely used in vitro model for motor neuron biology and pathology. We established a tetracycline-regulated gene expression system in this cell line by stably transfecting pTet-Off, which codifies for the tetracycline transactivator, the regulatory protein tTA. The monoclonal cell lines (NSC-34-tTA) were evaluated for the presence of functional...
PURPOSE To create the Tg(ccnb1:EGFP)(nt18) zebrafish line that spatially and temporally labels retinal progenitor cells with enhanced green fluorescent protein (EGFP) during zebrafish retinal development and regeneration. METHODS We cloned the 1.5 kb promoter region of the zebrafish cyclin B1 (ccnb1) gene upstream of the EGFP gene in the Tol2 vector, which was used to generate the stable Tg(c...
Reporter mouse strains are important tools for monitoring Cre recombinase-mediated excision in vivo. In practice, excision may be incomplete in a given population due to threshold level or variegated expression of Cre. Hence, it is desirable in many experimental contexts to isolate cells that have undergone excision to assess the consequences of gene ablation. To generate alternative reporter m...
The compartments of eukaryotic cells maintain a distinct protein composition to perform a variety of specialized functions. We developed a new method for identifying the proteins that are transported to the endoplasmic reticulum (ER) in living mammalian cells. The principle is based on the reconstitution of two split fragments of enhanced green fluorescent protein (EGFP) by protein splicing wit...
