Trypanosoma cruzi: identification of DNA targets of the nuclear periphery coiled-coil protein TcNUP-1.

The nuclear lamina is a structure that lines the inner nuclear membrane. In metazoans, lamins are the primary structural components of the nuclear lamina and are involved in several processes. Eukaryotes that lack lamins have distinct proteins with homologous functions.

Knockout of the gene encoding the kinetoplast-associated protein 3 (KAP3) in Trypanosoma cruzi: effect on kinetoplast organization, cell proliferation and differentiation.

Kinetoplast DNA (kDNA) of trypanosomatid protozoa consists of an unusual arrangement of two types of circular molecules catenated into a single network: (1) a few maxicircles that encode various mitochondrial enzyme subunits and rRNA in a cryptic pattern and (2) thousands of minicircles that encode guide RNAs (gRNAs). kDNA is associated with proteins, known as kinetoplast-associated proteins (KAPs), which condense the kDNA network. However, little is known about the KAPs of Trypanosoma cruzi, a parasite that displays different kDNA condensation patterns during its complex morphogenetic development.

Characterization of a novel Obg-like ATPase in the protozoan Trypanosoma cruzi.

We characterized a gene encoding an YchF-related protein, TcYchF, potentially associated with the protein translation machinery of Trypanosoma cruzi. YchF belongs to the translation factor-related (TRAFAC) class of P-loop NTPases. The coding region of the gene is 1185bp long and encodes a 44.
