Rbp1, as a RNA binding protein, was first identified as a negative growth regulator in Saccharomyces cerevisiae. Rbp1 contains three RNA recognition motif (RRM), two glutamine-rich regions, and asparagine-methionine-proline-rich (NMP) region in the C terminus. Our previous studies have shown that deletion of RBP1 resulting in a hyper ager-invasive growth in
