LmxMPK4, a mitogen-activated protein (MAP) kinase homologue essential for promastigotes and amastigotes of <Emphasis Type="Italic">Leishmania mexicana</Emphasis>

Background  

Leishmania parasites undergo profound morphological and biochemical changes while passing through their life cycle. Protein kinases have been shown to be involved in the differentiation from the extracellular flagellated promastigotes to the intracellular "non-flagellated" amastigotes and vice versa. Moreover, these enzymes are likely involved in the regulation of the proliferation of the different life stages.
