Protein Lounge is a San Diego-based provider of biological databases, research tools, and creative services for the life-sciences community. Its online platform brings together illustrated signaling and metabolic pathways, linked with protein information and gene and protein analysis resources. The database collection covers proteins, kinase-phosphatase relationships, transcription factors, peptide antigens, siRNA, GPCRs, and biochemical compounds.

Researchers can use web-based tools to build pathways and biological graphics, assess protein hydrophilicity or hydrophobicity, and find or generate peptide and siRNA resources. The site also offers tutorials and biological visualizations to support scientific communication and research workflows.

For pharmaceutical and biotechnology companies, Protein Lounge provides custom scientific animations, biological posters, pathways, graphics, and video content, along with scientific content writing. These materials are developed in collaboration with clients for their intended audiences and communication needs. The company also offers subscription access to its databases and tools for individual users and institutions, with institutional licensing available for broader access.
