The PDB is a comprehensive resource for protein structure data, offering a wealth of information on protein sequences and structures. It’s an essential tool for studying protein function and interactions.

PyMOL

PyMOL is a user-friendly molecular visualization system, allowing researchers to create high-quality images and animations of molecular structures. It’s particularly useful for visualizing protein structures and their interactions.

SWISS-MODEL

SWISS-MODEL is a fully automated protein structure homology-modeling server. It generates accurate 3D models of proteins based on their amino acid sequences, aiding in the study of protein structure and function.

Gene Expression Analysis Tools

GEO (Gene Expression Omnibus)

GEO is a comprehensive public database of gene expression data, including microarray, RNA-Seq, and other high-throughput functional genomics data. It’s a valuable resource for gene expression analysis and comparative studies.

KEGG (Kyoto Encyclopedia of Genes and Genomes)

KEGG is a collection of databases dealing with genomes, biological pathways, diseases, and drugs. It provides a wealth of information for pathway analysis and gene function studies.

DAVID (Database for Annotation, Visualization, and Integrated Discovery)

DAVID is a web-based tool that provides a comprehensive set of functional annotation tools for understanding biological meaning behind large lists of genes. It’s particularly useful for gene ontology (GO) and pathway analysis.

Epigenetics and Chromatin Analysis Tools

ENCODE (Encyclopedia of DNA Elements)

ENCODE is a comprehensive encyclopedia of functional elements in the human genome, including regulatory elements and protein binding sites. It’s an invaluable resource for epigenetics and chromatin studies.

ChIP-Seq Analysis Tools

ChIP-Seq analysis tools, such as MACS and SISSRs, are specifically designed for analyzing ChIP-Seq data. They help identify transcription factor binding sites and histone modification patterns, providing insights into gene regulation.
