Rho GTPases play a key role in the regulation of multiple essential cellular processes, including actin dynamics, gene… Expand Mature tRNA 3' ends in the yeast Saccharomyces cerevisiae are generated by two pathways: endonucleolytic and exonucleolytic… Expand The family Anostomidae is an interesting model for studies of repetitive elements, mainly because of the presence of high numbers… Expand Rex1/Zfp42 is a Yy1-related zinc-finger protein whose expression is frequently used to identify pluripotent stem cells. We show… Expand BackgroundTransposable elements (TEs) have the potential to produce broad changes in the genomes of their hosts, acting as a type… Expand Zfp42/Rex1 (reduced expression gene 1) is a well-known stem-cell marker that has been duplicated from YY1 in the eutherian… Expand Transposons and retrotransposons represent a great portion of the eukaryotic genome. These repeated elements can be defined as… Expand Rex1 (zfp42) is a zinc finger protein expressed primarily in undifferentiated stem cells, both in the embryo and the adult. Upon… Expand BackgroundRex1/Zfp42 has been extensively used as a marker for the undifferentiated state of pluripotent stem cells. However, its… Expand Rex1, together with the related BABAR: elements, represents a new family of non-long-terminal-repeat (non-LTR) retrotransposons… Expand
