Purity > 90% as determined by SDS-PAGE. MW: 33kDa. Full Length of Mature Protein: 2-157aa. N-terminal 6xHis-SUMO-tagged. Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast). mRNA-binding protein involved in translation elongation. Has an important function at the level of mRNA turnover, probably acting downstream of decapping. Involved in actin dynamics and cell cycle progression, mRNA decay and probably in a pathway involved in stress response and maintenance of cell wall integrity. Essential for polarized growth, a process necessary for G1/S transition. May mediate large range of effects of the polyamine spermidine in the cell.
