Indian proteomics efforts and human proteome project.

Area of Science:

• Proteomics
• Human Proteome Project
• Genomics

Background:

• The human proteome, comprising all proteins encoded by the human genome, is crucial for understanding biological functions and diseases.
• Previous efforts have generated draft maps and tissue-specific expression data of the human proteome.
• The Human Proteome Organization initiated the Chromosome-centric and Biology/Disease-centric Human Proteome Projects (C-HPP and B/D-HPP) for in-depth protein analysis.

Purpose of the Study:

• To highlight the complexity and challenges in deciphering the human proteome.
• To showcase the significant contributions of Indian researchers to international human proteome initiatives.
• To provide an overview of the ongoing C-HPP and its objectives.

Main Methods:

• Large-scale mass spectrometric analysis for protein identification.
• Antibody-based studies for protein expression and distribution across tissues and cells.
• Collaborative research within international consortia, including Asian teams focusing on specific chromosomes like Chromosome 12.

Main Results:

• Publication of draft maps of the human proteome, including identification of missing proteins.
• Establishment of a Tissue-based Human Proteome Map detailing protein expression patterns.
• Initial publications from an Asian consortium focusing on Chromosome 12, with substantial Indian involvement.
• Significant Indian contributions to both draft proteome maps and ongoing C-HPP initiatives.

Conclusions:

• Deciphering the human proteome is a complex and challenging endeavor requiring global collaboration.
• Indian researchers play a vital role in advancing human proteome research, particularly within the C-HPP framework.
• Continued participation and expansion of research efforts are essential for a comprehensive understanding of the human proteome in health and disease.
