What Charts Can Present Potentially Interacting Proteins Identified by Mass Spectrometry in a Paper
Potentially interacting proteins identified by mass spectrometry can be visualized using various graphical methods. Below are several commonly used approaches:
1. Protein Interaction Networks
This is one of the most intuitive methods for displaying protein interactions. Each node represents a protein, while edges between nodes indicate potential interactions. Edge thickness and color can be adjusted based on the strength or significance of the interactions.
2. Heatmaps
Heatmaps effectively visualize the strength of protein interactions, where each row and column represent a specific protein, and color intensity reflects interaction strength or frequency. This method is particularly suitable for large-scale protein interaction datasets.
3. Bar Charts or Dot Plots
When comparing interaction strengths between specific protein pairs or assessing differences under various experimental conditions, bar charts or dot plots provide a clear and concise visualization of changes in protein interaction strength.
4. Circos Plots
Circos plots offer a sophisticated yet visually compelling way to represent complex relationships in large-scale datasets, such as multi-protein interactions. In this format, proteins are arranged along the circumference of a circular layout, with interaction relationships depicted through connecting arcs.
5. Bubble Plots
Bubble plots are useful for visualizing multivariate data, such as protein interaction strength, interaction frequency, and an additional parameter related to interactions. The size and color of each bubble can represent different aspects of the dataset.
