Abstract
CPSF6 is a component of the CFIm complex, involved in mRNA 3'end processing. Despite increasing interest on this protein as a consequence of proposed roles in cancer and HIV infection, several aspects of CPSF6 biological function are poorly understood. In this work we studied the expression of the zebrafish ortholog cpsf6 in early stages of embryo development. Quantitative RT-PCR studies showed that zebrafish cpsf6 mRNA is maternally inherited and that its concentration markedly decreases during early development. We found a generalized distribution of cpsf6 mRNA in early stages through whole mount hybridization experiments. By performing Western blot, we also found a decrease in zebrafish Cpsf6 levels during development. Our analysis of the subcellular localization of this protein using a heterologous system showed a distinct pattern characterized by the presence of nuclear foci. We also studied the relevance of different protein domains on subcellular localization, showing that the C-terminal domain is critical for nuclear localization. Collectively, our results showed that cpsf6 expression changes during early development and that the subcellular localization of the protein is similar to that of the human ortholog.
