An analysis of proteomics and its applications

Abstract

Proteomics is the study of the identification and measurement of total protein content in a cell, tissue, or organism using various methods. It works in tandem with other “omics” technologies like genomics and transcriptomics to determine the identification of an organism's proteins and to understand their structure and activities. Proteomics-based technologies are used in a variety of research settings, including the detection of various diagnostic markers, vaccine candidates, pathogenicity mechanisms, the alteration of expression patterns in response to various signals, and the interpretation of functional protein pathways in various diseases. Proteomics is very complicated since it entails analyzing and categorizing a genome's total protein signatures. Mass spectrometry, with LC–MS–MS and MALDI-TOF/TOF as common equipment, is at the heart of today's proteomics. However, the expenses of using proteomics facilities, such as software for equipment, databases, and the need for trained people, significantly rise, limiting their usage, particularly in poor countries. Furthermore, because of intricate regulatory mechanisms that regulate protein expression levels, the proteome is extremely dynamic. This study aims to explain the different proteomics methods, as well as their current advancements and applications in research and analysis.
