  GFP BUNNY
Alba is a participant in the "GFP Bunny" transgenic artwork; so is anyone who comes in contact with her, and anyone who gives any consideration to the project.
"GFP Bunny" highlights the fact that transgenic animals are regular creatures that are as much part of social life as any other life form, and thus are deserving of as much love and care as any other animal [16].
"GFP Bunny" does not propose any new form of genetic experimentation, which is the same as saying: the technologies of microinjection and green fluorescent protein are established well-known tools in the field of molecular biology.

 GFP Symposium backround information
GFP applications abound in such areas as cell and developmental biology, neurobiology, and cytology where the time and location of specific gene activation can be determined by fluorescence microscopy, confocal microscopy, and image intensification.
GFP is also being developed for use in high throughput cell-based diagnostic tests for drugs, food additives, herbicides, pesticides, carcinogens, mutagens, teratogens, and other potentially hazardous chemicals.
The brilliant fluorescence of GFP and the ability to manipulate and express the GFP gene in foreign cells and organisms make this protein an ideal tool for laboratory instruction in biotechnology at all educational levels from grade school through postgraduate.

 Green Fluorescent Protein - GFP
Now GFP is found in laboratories all over the world where it is used in every conceivable plant and animal.
This is done by joining the GFP gene to the gene of the protein of interest so that when the protein is made it will have GFP hanging off it (see Figure below).
Since GFP fluoresces one can shine light at the cell and wait for the distinctive green fluorescence associated with GFP to appear.

 GFP tags for the Synapse
GFP is a very stable molecule and the chromophore is well protected and in a very insulated local environment in the middle of the cylinder.
Nevertheless, both N- and C- terminal fusions are fluorescent consistent with the N- and C-terminus of GFP being flexible enough not to disrupt the general structure of the molecule.
In this case, GFP is added the N- instead of C-terminus because RAB-3 is post-translationally modified with the addition of a geranylgeranyl hydrophobic moiety to C-terminal cysteines which act as its anchor to the synaptic vesicle membrane.

GFP is a 27 kDa protein from the pacific jellyfish Aequorea victoria.
GFP is normally in a complex with aequorin, a protein that emits blue light when it binds to calcium.

 GFP Structure   (Site not responding. Last check: 2007-10-26)
GFP is very resistant to denaturation, requiring treatment with 6 M guanidinium hydrochloride at 90° centigrade or a pH smaller than four or greater than twelve [6].
This is due to the fact that both termini of GFP appear rather flexible on the surface of the beta-can, so that GFP's structure is not significantly distorted or destroyed by the fused protein.
GFP has a single tryptophan, Trp 57 (blue), which is located 13 to 15 Å away from the chromophore (red) [7].

 TechOnline | Transparent Generic Framing Procedure (GFP)
GFP standardization began in the ANSI-accredited T1X1 subcommittee, which chose to work with the ITU-T for the final version of the standard that has been published by the ITU-T. The transparent version of GFP has been optimized for transparently carrying block-coded client signals with a minimum of latency.
The payload area of the GFP frame is scrambled with a self-synchronous scrambler to address both the physical properties of the transport medium and the desire for robustness in public networks.
Far-end client-specific performance reporting allows both ends of the GFP link to see the status of both directions of the GFP link, which is valuable when one of the ends is in an unmanned office or when the link crosses carrier domains.

 GFP Chromophore   (Site not responding. Last check: 2007-10-26)
GFP is unique among fluorescent proteins in that its fluorophore is not a seperately synthesized prostethic group but composed of modified amino acid residues within the polypeptide chain.
Denatured GFP is not fluorescent and its absorbtion spectrum is significantly different from native GFP [1], which implies that noncovalent interactions of the chromophore with its local environment have a great influence on the spectral characteristics and that fluorescence is mediated by amino acids close to the chromophore in the tertiary structure of GFP.
GFP is the first known example of a Förster cycle within the core of a protein [5,6,7]:

 CommsDesign - Handling GFP Implementation Tradeoffs in Metro Designs
Multiple GFP engine architectures are possible: the GFP protocol may be contained wholly in a framer device, it may be contained wholly in the link-layer device, it may be completely integrated into a monolithic device, or it may be distributed between a link-layer device and a framer device.
This mapping process forms a transparent L2 connection since the client data stream recreated at the egress side by the egress GFP engine is equivalent to the data stream presented to the ingress GFP engine with the exception of client protocol idle characters created or deleted for rate adaptation.
The lowest-level GFP functions such as idle insertion and removal, receive synchronization and delineation, payload scrambling, and GFP frame FCS insertion/checking are present in the framer device.

 Circular permutant gfp insertion folding reporters patent invention
[0006] In contrast to earlier described GFP folding reporter systems, in which a test protein is expressed as a C-terminal fusion with GFP in its native topology, the invention provides for test protein insertion within a circularly permuted fluorescent protein structure, specifically, between the native N- and C-termini of the fluorescent protein structure.
C-terminal GFP folding reporters are unable to discriminate between artifact (i.e., a truncated protein) and a full length protein.
For example, GFPcp9/8_FR/SF means that the GFP fragment in front of the guest insert protein is derived from folding reporter GFP, and the designation SF means the fragment of GFP after the guest insert protein is derived from superfolder GFP.

 Generic Frame Protocol
The Generic Frame Protocol (GFP), jointly developed at SRI International and Stanford University, provides a set of functions that support a generic interface to underlying frame representation systems (FRSs).
GFP is based upon a generic model of frame representation systems (with frames, classes, slots, etc.) and consists of a set of access functions (e.g., get a frame by its name, change a slot's value in a frame).
While GFP necessarily imposes some common requirements on the organization of knowledge (e.g., frames, slots, and values) and semantics of some assertions (e.g., instances and subclass relationship, and inherited slot values, slot constraints), it allows for some variety in the behavior of underlying FRSs.

 BioMed Central | Full text | Imaging plant cell death: GFP-Nit1 aggregation marks an early step of wound and herbicide ...
In the course of a screen for useful GFP fusion proteins [24], we observed that a GFP-Nitrilase 1 fusion protein exhibited a change of aggregation state in response to wounding.
The N6 marker possesses a low background level of cytoplasmic GFP localization that might mask the release of nuclear contents and also may be partially immobilized from the bulk nucleoplasm by an association with DNA (this marker illuminates chromosomes during mitosis, [26]).
Exclusion of cytosolic GFP from the interior of the lobes might be expected if this were true, since the space between the inner and outer nuclear envelopes, the peri-nuclear space, is contiguous with the lumen of the ER and thus isolated from the cytoplasm.

The advent of green fluorescent protein (GFP) as a means to tag and visualize proteins of interest in living cells has begun a revolution in cell and developmental biology.
One of the most important aspects of the Wee-P GFP fusion proteins is that the expression is controlled by native regulatory sequences so the GFP-fusions can be expressed in the correct spatial and temporal patterns, as well as at the correct levels.
Of the fusion proteins with essential genes that we have isolated to date, the vast majority are homozygous viable P-element insertions indicating that normal gene function is retained.
