RNA-binding protein that binds specific mRNAs including the ASH1 mRNA, coding for a repressor of the HO endonuclease. Part of the mRNA localization machinery that restricts accumulation of certain proteins to the bud and in the daughter cell (By similarity). Homodimer and homotetramer. Shuttles between the nucleus and cytoplasm and is exported in an mRNA-dependent manner. The presence in the nucleus is essential for PUF6 and LOC1 to bind the ASH1 mRNA. Belongs to the SHE2 family.
