Summary
The PONGO web server integrates four state-of-the-art topology predictors for analyzing membrane proteins. This tool provides simultaneous, comparative analysis of protein topology predictions, enhancing bioinformatics research.
Area of Science:
- Bioinformatics
- Computational Biology
- Genomics
Background:
- The BIOSAPIENS European Network of Excellence developed distributed annotation systems (DAS) to integrate bioinformatics resources and annotate metazoan genomes.
- The PONGO DAS server initially provided predictive annotations for all-alpha membrane proteins in the human genome.
Purpose of the Study:
- To present a new web server that consolidates multiple state-of-the-art topology predictors for membrane proteins.
- To enable interactive comparison and evaluation of four different topology predictions simultaneously for any given protein sequence.
Main Methods:
- Integration of four high-scoring topology predictors: TMHMM2.0, MEMSAT, PRODIV, and ENSEMBLE1.0.
- Inclusion of signal peptide prediction using SPEP.
- Development of a user-friendly web interface for direct querying and graphical display of results.
Main Results:
- The PONGO web server offers a unified framework for predicting and comparing membrane protein topology.
- It allows analysis of putative membrane proteins from any organism, providing consistent sequence profiles.
- Pre-computed predictions for human proteins are searchable and displayed graphically.
Conclusions:
- The PONGO web server facilitates comprehensive and comparative analysis of membrane protein topology.
- It serves as a valuable tool for researchers in bioinformatics and computational biology.
- The integrated approach enhances the accuracy and utility of protein topology predictions.

01:09Multi-pass Transmembrane Proteins and β-barrels
In multi-pass transmembrane proteins, the polypeptide chain crosses the membrane more than once. The transmembrane polypeptide chain either forms an α-helix or β-strand structure. α-Helix containing multi-pass transmembrane proteins are ubiquitous, whereas β-strand containing ones are mainly found in gram-negative bacteria, mitochondria, and chloroplasts.

01:25Single-pass Transmembrane Proteins
Integral membrane proteins are tightly associated with the cell membrane and play a crucial role in cell communication, signaling, adhesion, and transport of the molecules. Some integral membrane proteins are present only in the membrane monolayer. For example, the enzyme fatty acid amide hydrolase is present in the cytoplasmic side of the membrane monolayer. In contrast, another type of integral membrane protein, also known as a transmembrane protein, spans across the membrane. Transmembrane...
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...

01:29Insertion of Multi-pass Transmembrane Proteins in the RER
The rough ER membrane synthesizes, assembles, and embeds transmembrane proteins in diverse topologies. These proteins function as transporters or channels and can remain in the ER membrane or are sent to the Golgi complex, lysosome, and cell membrane.
The multipass transmembrane proteins are the type IV integral membrane proteins with multiple topogenic sequences determining their spatial arrangement in the ER membrane. Nearly all multipass proteins lack a cleavable signal sequence and use...

01:24Protein Diffusion in the Membrane
Proteins show rotational as well as lateral diffusion across the membrane. The lateral diffusion of proteins was confirmed through the cell fusion experiment where mouse and human cells were fused, resulting in hybrid cells. When the human and mouse cells fused, the specific membrane proteins on human and mouse cells were marked with the red and green-fluorescent markers, respectively. Initially, the red and green fluorescence was located on the respective hemisphere of the cell. As time...
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...
