Metaproteomics Initiative Reviews Five Years of Community-Driven Standardization and Benchmarking (microbiomejournal.biomedcentral.com)

• Global community-led metaproteomics network established in 2021; now has elected board, open membership, and 24 co-authors from multiple institutions.
• CAMPI benchmarking series includes three completed studies (CAMPI-1, -2, -3) and three more in preparation (quantification, unknown proteins, multi-omics).
• Future Grand Metaproteome Challenges aim to coordinate large-scale functional microbiome research across health, agriculture, and environment.

"The Metaproteomics Initiative, launched in 2021, has grown into a structured global network advancing metaproteomics through three pillars: communication/collaboration, education/outreach, and standardization. It has organized International Metaproteomics Symposia (IMS), conducted CAMPI benchmarking studies (CAMPI-1, CAMPI-2, with more planned), published educational resources, and developed metadata standards like SDRF-Proteomics templates. The Initiative now proposes 'Grand Metaproteome Challenges' for large-scale coordinated research across clinical, industrial, and environmental domains. Governance is by an elected Executive Board, with open membership and working groups."
