Crystal structure of the Aequorea victoria green fluorescent protein.

TLDR
The green fluorescent protein (GFP) from the Pacific Northwest jellyfish Aequorea victoria has generated intense interest as a marker for gene expression and localization of gene products.
Abstract
The green fluorescent protein (GFP) from the Pacific Northwest jellyfish Aequorea victoria has generated intense interest as a marker for gene expression and localization of gene products. The chromophore, resulting from the spontaneous cyclization and oxidation of the sequence -Ser65 (or Thr65)-Tyr66-Gly67-, requires the native protein fold for both formation and fluorescence emission. The structure of Thr65 GFP has been determined at 1.9 angstrom resolution. The protein fold consists of an 11-stranded beta barrel with a coaxial helix, with the chromophore forming from the central helix. Directed mutagenesis of one residue adjacent to the chromophore, Thr203, to Tyr or His results in significantly red-shifted excitation and emission maxima.

Fluorescent indicators for Ca2+based on green fluorescent proteins and calmodulin

TL;DR: New fluorescent indicators for Ca2+ that are genetically encoded without cofactors and are targetable to specific intracellular locations are constructed and dubbed ‘cameleons’.

Cre reporter strains produced by targeted insertion of EYFP and ECFP into the ROSA26 locus

TL;DR: In contrast to existing lacZ reporter lines, where lacZ expression cannot easily be detected in living tissue, the EYFP and ECFP reporter strains are useful for monitoring the expression of Cre and tracing the lineage of these cells and their descendants in cultured embryos or organs.

Imaging neuronal subsets in transgenic mice expressing multiple spectral variants of GFP.

TL;DR: Each of 25 independently generated transgenic lines expressed XFP in a unique pattern, even though all incorporated identical regulatory elements (from the thyl gene), for example, all retinal ganglion cells or many cortical neurons were XFP positive in some lines, whereas only a few ganglions or only layer 5 cortical pyramids were labeled in others.

Improved methods for building protein models in electron density maps and the location of errors in these models.

TL;DR: In this paper, the authors describe strategies and tools that help to alleviate this problem and simplify the model-building process, quantify the goodness of fit of the model on a per-residue basis and locate possible errors in peptide and side-chain conformations.

Green fluorescent protein as a marker for gene expression

TL;DR: A complementary DNA for the Aequorea victoria green fluorescent protein produces a fluorescent product when expressed in prokaryotic or eukaryotic cells, which can be used to monitor gene expression and protein localization in living organisms.

The interpretation of protein structures: estimation of static accessibility.

TL;DR: The accessibility of atoms in the twenty common amino acids in model tripeptides of the type Ala-X-Ala are given for defined conformation and the larger non-polar amino acids tend to be more “buried” in the native form of all three proteins.
