Import and simulate the model from pantherdb and understand the functions of genes based on their evolutionary relationships using pantherdb in CellDesigner





Protein Analysis through Evolutionary Relationships (PANTHER) is a comprehensive system for understanding the functions of genes from the ancestor to the modern genes based on their evolutionary relationships. Pantherdb gives information about Gene of interest. It searches for protein families, molecular functions, biological process and pathways. It generates the information about the genes that belong to a given protein family or sub family and analyze the lists of genes and proteins based on family, molecular function, biological process, cellular component or pathways. The main function of PANTHER is the accurate prediction of the functions of uncharacterized genes, based on their evolutionary relationships between genes. It also includes tools for analyzing genomic data which is relative to known and inferred gene functions. One can easily download the pathways from PANTHER in System Biology Markup Language (SBML) format, so it is easy to view the model using CellDesigner.


Important features of Pantherdb:


  • Whole genome sequence coverage from 48 genomes (upto 87% of genes).


  • New tree building algorithm (GIGA) for improved phylogenetic relationships of genes and families.


  • Improved Ortholog identification.


  • Improved Hidden Markov Models.


  • Expanded sets of genomes and sequence identifier for PANTHER tools.


  • PANTHER Pathway diagram represents in SBGN.

Systems biology deals with mainly modeling of biological systems at system level. The main purpose of CellDesigner is to draw biological networks using the symbolic notation, this system is proposed by Kitano. It is easy to retrieve the model from the databases.


Features of cell designer :


  •  User can draw reaction easily

It is easy to make a model or to build a network based on mathematical equations.


  • The user can open a model from a pre-existing repository

Repository (database) allows one to store, search, and retrieve the mathematical models. These models are curated with the external resources like publications, ontologies, databases of compounds and pathways. 


  • Data can be read and written in SBML format

Different format is needed for computing a model to the point where it can be simulated and analyzed. Systems Biology Markup Language (SBML) is used for analyzes.


  • Simulate the reactions by changing the conditions and can view results graphically.

Select a particular model and run the simulation by changing the parameters. The results can be viewed graphically with the time on the X-axis and species (or substances) on the Y-axis. It implies that, what will be expression of particular substance at a particular time, based on an equation.
