{Reference Type}: Journal Article {Title}: Protein Engineering for Improved Health: Technological Perspectives. {Author}: Mandeep ;Sinha R;Shukla P; {Journal}: Curr Protein Pept Sci {Volume}: 20 {Issue}: 9 {Year}: 2019 {Factor}: 3.118 {DOI}: 10.2174/138920372009190917095307 {Abstract}: Protein engineering has enabled development of novel proteins aimed at disease diagnosis, alleviation and improved health attributes. The present article provides an overview of recent approaches and techniques used to modify proteins at diverse levels, which find therapeutically relevant applications. There is immense interest among researchers to discover new and increasingly valuable solutions for various health related issues and protein engineering could be a possible venue to sort out such problems. In this mini review we have tried to decipher some of the novel aspects of protein engineering in terms of protein-based therapeutics and diagnostics, in-silico tools and related approaches. A special emphasis has been given for some innovative aspects of protein-nanoparticle conjugates; use of artificial intelligence (AI)- based tools and post-translational modifications. Utilization of such approaches in protein engineering might be ground breaking in future research endeavor of researchers across the world.
