RNA-binding protein that recognizes the sequence AUACCC via its tandem KH domains 3 and 4, probably in order to promote mRNA instability (PubMed:19854870). Plays an essential role in filamentous growth and virulence (PubMed:15643068). The tandem KH domains 3 and 4 are essential for AUACCC binding. Affects cell growth, pheromone response, filamentation, cell morphology, as well as pathogenicity (PubMed:15643068). Leads to increased levels of mRNAs containing the AUACCC sequence (PubMed:19854870).
