Lipid rafts are membrane microdomains rich in cholesterol, glycosphingolipids, and certain proteins that are highly organised. They play a role in biological activities in a variety of cell types, including mast cells (MCs). The protein composition of the MC lipid raft was determined utilising qualitative mass spectrometric analysis of the proteome extracted from detergent-resistant membrane fractions from RBL-2H3 MCs. A total of 949 lipid raft related proteins were discovered using two separate post-isolation treatment approaches. The bulk of these MC lipid raft proteins have already been documented in the RaftProtV2 database and are among the most frequently cited and experimentally validated lipid raft proteins. proteins. Furthermore, almost half of the proteins discovered showed lipid modifications and/or transmembrane domains. The proteins were shown to be connected with cellular membrane compartments and biological and molecular functions such as regulation, localisation, binding, catalytic activity, and stimulus response after they were classified into functional categories. Furthermore, functional enrichment analysis revealed that identified proteins are intimately involved in numerous areas of MC biological activities, particularly those related to controlled secretion, macromolecule complex organization/stabilization, and so on.
