Figure 4: Gene Ontology distributions for subcellular location function and biological process of identified MPs according to UniProt database. a- Subcellular location of MPs. 53.4% of MPs belongs to cell membrane, while 22.5% of MPs are related to intracellular and 24.1% are with other unspecified membrane. b- Function of MPs. The GO distribution function showed several special groups: (i) enzymes that make up the highest rate with 24.8% (361 proteins); (ii) the binding MPs; (iii) MPs with specific functions (receptor, structure, transporter immune response, transcription, enzyme activator, and enzyme inhibitor); (iv) group of MPs with unknown function (13.3%, 194 proteins). c- Biological process. There were 17 subgroups classified based on GO annotation.
