Proteogenomic approaches for snake venom protein-based drug development: current trends and challenges.

Snake venom proteins have long been recognized for their therapeutic potential. Proteogenomic strategies, integrating transcriptomics and proteomics, have emerged as powerful tools for identifying and characterizing venom proteins for the development of novel therapeutic agents. Analytical techniques like mass spectrometry and next-generation sequencing enable comprehensive analysis, identifying key venom components and their variants. Recent studies unveil the diversity and complexity of snake venom, highlighting species-specific variations in toxin composition. Structural biology techniques, including x-ray crystallography and cryo-electron microscopy, provide insights into venom enzyme structures and mechanisms of action, facilitating drug design. Bioinformatics tools aid in data analysis and prediction of venom protein functions, enhancing drug discovery efforts. Despite advancements, challenges persist, including toxicity, formulation stability and clinical validation. This review describes the current as well as future options for research and development and emphasizes the critical role of proteogenomic techniques in developing snake venom protein-based drugs.
