Protein interactions within the TcZFP zinc finger family members of Trypanosoma cruzi: Implications for their functions
The small zinc finger proteins tbZFP1 and tbZFP2 have been implicated in the control of Trypanosoma brucei differentiation to the procyclic form. Here, we report that the complete ZFP family in Trypanosoma cruzi is composed by four members, ZFP1A and B, and ZFP2A and B. ZFP1B is a paralog specific g...

ZFP1B is a paralog specific gene restricted to T. cruzi, while the ZFP2A and B paralogs diverged prior to the trypanosomatid lineage separation.

Also, TcZFP2B strongly homodimerizes by a glycine rich region absent in TcZFP2A. We propose a model to discuss the relevance of these protein-protein interactions in terms of the functions of these proteins. © 2005 Elsevier Inc.
