Summary
Inferring protein function is possible using the "guilt by association" method. This approach analyzes gene fusion events across genomes to predict functional links between proteins, aiding in new gene characterization.
Area of Science:
- Genomics
- Proteomics
- Bioinformatics
Background:
- Proteins with unknown functions pose a challenge in biological research.
- Understanding protein function is crucial for elucidating metabolic pathways and cellular processes.
Purpose of the Study:
- To present a method for inferring functional links between proteins using gene fusion events.
- To leverage the
- guilt by association
- principle for hypothesis generation in protein function studies.
- To guide experimental characterization of proteins with limited homology.
Main Methods:
- Analyzing gene fusion events where two genes are transcribed as a single transcript.
- Utilizing the FusionDB database for characterized gene fusion events, including multiple sequence alignments and orthologous gene information.
- Employing phylogenetic tree reconstruction and 3D protein structure analysis to understand fusion event history and nature.
- Providing guidance on using public web tools for analyzing genes not present in FusionDB.
Main Results:
- Gene fusion events suggest functional linkage between proteins, potentially involved in the same pathway or complex.
- The method is particularly useful for novel proteins lacking homology to known ones.
- FusionDB offers a comprehensive resource for studying gene fusion events.
Conclusions:
- The gene fusion analysis method provides valuable insights for predicting protein function.
- This approach aids in building hypotheses and directing experimental research for uncharacterized proteins.
- Integration with other non-homology methods enhances the utility of gene fusion analysis.

02:07FISH - Fluorescent In-situ Hybridization
Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...
02:32Exon Recombination
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.

02:11Reporter Genes
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

02:24Ribosome Profiling
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

01:16In-vitro Mutagenesis
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
02:08Gene Conversion
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...
