| description | Phosphorylation dynamically regulates the function of proteins by maintaining a balance between protein kinase and phosphatase activity. A comprehensive understanding of the role phosphatases in cellular signaling is lacking in case of protozoans of medical and veterinary importance worldwide. The drugs used to treat protozoal diseases have many undesired effects and the development of resistance, highlights the need for new effective and safer antiprotozoal agents. In the present study we have analyzed phosphatomes of 15 protozoans of medical significance. We identified ~2000 phosphatases, out of which 21% are uncharacterized proteins. A significant positive correlation between phosphatome and proteome size was observed except for E. histolytica, having highest density of phosphatases irrespective of its proteome size. A difference in the number of phosphatases among different genera shows the variation in the signaling pathways they are involved in. The phosphatome of parasites is dominated by ser/thr phosphatases contrary to the vertebrate host dominated by tyrosine phosphatases. Phosphatases were widely distributed throughout the cell suggesting physiological adaptation of the parasite to regulate its host. 20% to 45% phosphatome of different protozoa consists of ectophosphatases, i.e. crucial for the survival of parasites. A database and a webserver "ProtozPhosDB" can be used to explore the phosphatomes of protozoans of medical significance. |
