Summary
We present an improved Rankprop algorithm for protein homology ranking, now accessible via a web server. This enhanced tool analyzes a larger protein network, offering more accurate and interpretable results for researchers.
Area of Science:
- Bioinformatics
- Computational Biology
- Genomics
Background:
- The Rankprop algorithm is a tool for ranking protein homology.
- Previous implementations were limited to smaller protein databases.
Purpose of the Study:
- To present a large-scale implementation of the Rankprop protein homology ranking algorithm.
- To introduce algorithmic improvements for enhanced accuracy and probabilistic score interpretation.
Main Methods:
- Implementation of the Rankprop algorithm as an openly accessible web server.
- Construction of a protein similarity network using NRDB40 PSI-BLAST all-versus-all comparison for 1.1 million proteins.
- Incorporation of algorithmic improvements: propagation from multiple homologs and improved normalization of ranking scores.
Main Results:
- A large-scale implementation of Rankprop is now available as a web server.
- The analysis was scaled to a network of 1.1 million proteins, significantly larger than previous studies.
- Algorithmic improvements resulted in higher accuracy and probabilistic interpretation of homology ranking scores.
Conclusions:
- The enhanced Rankprop web server provides a powerful and accessible tool for large-scale protein homology ranking.
- The algorithmic improvements enhance the reliability and interpretability of homology predictions.
- This resource facilitates advancements in comparative genomics and protein function prediction.

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...

02:47Protein Families
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism. Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members. If these new proteins contain similar amino acids in key locations, protein...

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.

01:29Protein Folding Quality Check in the RER
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...
