PABPs are high-affinity poly(A)-binding proteins that are implicated in the regulation of translation initiation, RNA stability and other important biological processes. We describe a PABP from Leishmania infantum (LiPABP) that shows a very high homology with PABPs from other eukaryotic organisms, including mammals and other parasites. LiPABP conserves the main domains present in other PABPs, maintains poly(A)-binding properties and is phosphorylated by p38 mitogen-activated protein kinase. Using the sera from dogs infected with L. infantum, we demonstrate that LiPABP is expressed in L. infantum promastigotes. %~
