Summary
ProFAT is a new web tool that helps scientists annotate protein functions. It uses sequence similarity and text mining to find biologically relevant protein relationships, improving functional prediction.
Area of Science:
- Bioinformatics
- Computational Biology
- Proteomics
Background:
- Protein functional annotation heavily relies on identifying homologous sequences in databases.
- Existing tools often lack the ability to integrate functional information into sequence similarity searches.
- Discovering remote homologues is crucial for comprehensive protein function prediction.
Purpose of the Study:
- To introduce ProFAT, a novel web-based tool for protein sequence functional annotation.
- To enable the identification of weak but biologically relevant protein homologues.
- To enhance protein function prediction by leveraging remote sequence similarity and functional context.
Main Methods:
- ProFAT integrates sensitive sequence database search methods and fold recognition algorithms.
- It employs a text-mining approach to extract biological background information from annotations and literature.
- Users can provide custom keyword lists to refine searches for specific homologues.
Main Results:
- ProFAT correctly identified 90-100% of domain family members in evaluated datasets.
- The tool successfully identified weak relatives within protein domain families.
- ProFAT demonstrated utility in predicting functions of proteins across diverse cellular contexts.
Conclusions:
- ProFAT effectively detects remote yet biologically relevant protein relationships.
- The tool enhances protein function prediction by combining sensitive search algorithms with functional data.
- ProFAT assists researchers in understanding protein function based on remote homologies.

03:36Genome Annotation and Assembly
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
02:26Protein Networks
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

02:26Conservation of Protein Domains Over Different Proteins
Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to form...

02:04Protein-protein Interfaces
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...
01:24Tagging and Fusion Proteins
Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from the other proteins in the cell. This is achieved by overexpressing the specific gene in a suitable host to produce large quantities of the target protein. A tag or label is recombined with the gene to produce a fusion protein containing the target protein and the tag. The tags on these fusion proteins can then be used for easy detection and...
